Randy Dunlap f6c5c1f96d platform/x86: fix surface3_button build errors
Fix build errors when I2C=m and SURFACE_3_BUTTON=y.
The driver uses i2c interfaces so it should depend on I2C.

drivers/built-in.o: In function `surface3_driver_init':
surface3_button.c:(.init.text+0x75cb0): undefined reference to `i2c_register_driver'
drivers/built-in.o: In function `surface3_driver_exit':
surface3_button.c:(.exit.text+0x31a8): undefined reference to `i2c_del_driver'

Fixes: 1a64b719d3 (platform/x86: Introduce button support for the Surface 3)

Thomas Gleixner 8b0e195314 ktime: Cleanup ktime_set() usage
ktime_set(S,N) was required for the timespec storage type and is still
useful for situations where a Seconds and Nanoseconds part of a time value
needs to be converted. For anything where the Seconds argument is 0, this
is pointless and can be replaced with a simple assignment.

Benjamin Tissoires 1a64b719d3 platform/x86: Introduce button support for the Surface 3
The Surface 3 is not following the ACPI spec for PNP0C40, but nearly.
The device is connected to a I2C device that might have some magic
but we don't know about.
Just create the device after the enumeration and use the declared GPIOs
to provide button support.

This driver is just an adaptation of drivers/input/misc/soc_button_array.c

The Surface Pro 3 is using an ACPI driver and matches against the bid
of the device ("VGBI"). To prevent this incompatible driver to be used
on the Surface Pro, we add a match on the Surface 3 bid "TEV2".

Benjamin Tissoires 3dda3b3798 platform/x86: Add custom surface3 platform device for controlling LID
The LID state provided by ACPI on the Surface 3 is not accurate.
The ACPI node doesn't get notified on LID open, which means the
LID input switch stays close most of the time.

Fortunatelly, there is a WMI method which directly queries the
GPIO underneath the LID state, so it's far more reliable than ACPI.
To get the notifications that the LID was opened/closed, we can
rely on the ACPI notification of the touchscreen: the DSDT shows
that the touchscreen will get notified on close/open as it also
controls its _STA method.

Note that we need to set the tag "power-switch" to the LID
input node through a udev rule for logind to accept it:

SUBSYSTEM=="input", KERNEL=="event*", KERNELS=="surface3-wmi", \
	TAG+="power-switch"

Lyude b318002838 platform/x86: thinkpad_acpi: Move tablet detection into separate function
The hotkey events and ACPI handles used for detecting tablet mode on a
few of the newer thinkpad models (Yoga X1 and the Yoga 260 specifically)
have been changed around, so unfortunately this means we're definitely
going to need to probe for multiple types of tablet mode support. Since
the hotkey_init() is already a lot larger than it should be, let's split
up this detection into its own function to make things a little easier
to read.

As well, since we're going to have multiple types of tablet modes, make
hotkey_tablet into an enum so we can also use it to indicate the type of
tablet mode reporting the machine supports.

By referencing Intel Platform Controller Hub(PCH) datasheet,
the xHC USB 2.0 Port Routing(XUSB2PR) at offset 0xD0-0xD3h
decides the setting of mapping the port to EHCI controller or
xHC controller. And the port mapped to xHC will enable xHCI
during bus resume.

The setting of disabling bluetooth adapter's connected port is
0x000001D9. The value can be obtained by few times 1 bit flip
operation. The suited configuration should have the 'lsusb -t'
result with bluetooth using ehci:

Rajneesh Bhardwaj 173943b3da platform/x86: intel_pmc_core: ModPhy core lanes pg status
The PCH implements a number of High Speed I/O (HSIO) lanes that are split
between PCIe*, USB 3.0, SATA, GbE, USB OTG and SSIC. This patch shows the
current power gating status of the available ModPhy Core lanes. This is
done by sending a message to the PMC (MTPMC) that contains the XRAM
register offset for the MPHY_CORE_STS_0 and MPHY_CORE_STS_1 and then by
reading the response sent by the PMC (MFPMC).

While enabling low power modes we often encounter situations when the
ModPhy lanes are not power gated and it becomes hard to debug which lane is
active and which is not in the absence of an external hardware debugger
(JTAG/ITP). This patch eliminates the dependency on an external hardware
debugger for reading the ModPhy Lanes power gating status.

This patch requires PMC_READ_DISABLE setting to be disabled in the platform
bios.

Rajneesh Bhardwaj 0bdfaf429d platform/x86: intel_pmc_core: Add PCH IP Power Gating Status
This patch adds the support for reading the power gating status of various
devices present on Sunrise Point PCH. This is intended to be used for
debugging purpose while tuning the platform for power optimizations and
also to understand which devices (on PCH) are blocking the system to enter
a low power state.

Power Management Controller on Sunrise Point PCH provides access to "PGD
PFET Enable Ack Status Registers (ppfear)". This patch reads and decodes
this register and dumps the output in formatted manner showing various
devices present on the PCH and their "Power Gating" status.

Further documentation can be found in Intel 7th Gen Core family mobile u/y
processor io datasheet volume 2.

The AMW0_GUID1 wmi is not only found on Acer family but also other
machines like Lenovo, Fujitsu and Medion. In the past, acer-wmi handled
those non-Acer machines by quirks list.

But actually acer-wmi driver was loaded on any machine that had
AMW0_GUID1. This behavior is strange because those machines should be
supported by appropriate wmi drivers. e.g. fujitsu-laptop,
ideapad-laptop.

This patch adds the logic to check the machine that has AMW0_GUID1
should be in Acer/Packard Bell/Gateway white list. But, it still keeps
the quirk list of those supported non-acer machines for backward
compatibility.

We have a couple of drivers, acpi_apd.c and acpi_lpss.c,
that need to pass extra build-in properties to the devices
they create. Previously the drivers added those properties
to the struct device which is member of the struct
acpi_device, but that does not work. Those properties need
to be assigned to the struct device of the platform device
instead in order for them to become available to the
drivers.

To fix this, this patch changes acpi_create_platform_device
function to take struct property_entry pointer as parameter.

Azael Avalos 1c80e9603f toshiba-wmi: Fix loading the driver on non Toshiba laptops
Bug 150611 uncovered that the WMI ID used by the toshiba-wmi driver
is not Toshiba specific, and as such, the driver was being loaded
on non Toshiba laptops too.

This patch adds a DMI matching list checking for TOSHIBA as the
vendor, refusing to load if it is not.

Also the WMI GUID was renamed, dropping the TOSHIBA_ prefix, to
better reflect that such GUID is not a Toshiba specific one.

Linus Torvalds 63ae602cea Merge branch 'gup_flag-cleanups'
Merge the gup_flags cleanups from Lorenzo Stoakes:
 "This patch series adjusts functions in the get_user_pages* family such
  that desired FOLL_* flags are passed as an argument rather than
  implied by flags.

  The purpose of this change is to make the use of FOLL_FORCE explicit
  so it is easier to grep for and clearer to callers that this flag is
  being used.  The use of FOLL_FORCE is an issue as it overrides missing
  VM_READ/VM_WRITE flags for the VMA whose pages we are reading
  from/writing to, which can result in surprising behaviour.

  The patch series came out of the discussion around commit 38e0885465
  ("mm: check VMA flags to avoid invalid PROT_NONE NUMA balancing"),
  which addressed a BUG_ON() being triggered when a page was faulted in
  with PROT_NONE set but having been overridden by FOLL_FORCE.
  do_numa_page() was run on the assumption the page _must_ be one marked
  for NUMA node migration as an actual PROT_NONE page would have been
  dealt with prior to this code path, however FOLL_FORCE introduced a
  situation where this assumption did not hold.

  See

      https://marc.info/?l=linux-mm&m=147585445805166

  for the patch proposal"

Additionally, there's a fix for an ancient bug related to FOLL_FORCE and
FOLL_WRITE by me.

[ This branch was rebased recently to add a few more acked-by's and
  reviewed-by's ]

  mm: replace access_process_vm() write parameter with gup_flags

Lorenzo Stoakes 768ae309a9 mm: replace get_user_pages() write/force parameters with gup_flags
This removes the 'write' and 'force' from get_user_pages() and replaces
them with 'gup_flags' to make the use of FOLL_FORCE explicit in callers
as use of this flag can result in surprising behaviour (and hence bugs)
within the mm subsystem.

A recent bugfix added a call to i8042_install_filter but did
not add the dependency, leading to possible link errors:

drivers/platform/built-in.o: In function `asus_nb_wmi_quirks':
asus-nb-wmi.c:(.text+0x23af): undefined reference to `i8042_install_filter'

This adds a dependency on SERIO_I8042||SERIO_I8042=n to indicate
that we can build the driver when the i8042 driver is disabled,
but it cannot be built-in when that is a loadable module.

Arnd Bergmann 127595ed21 platform/x86: intel_pmc_core: avoid boot time warning for !CONFIG_DEBUGFS_FS
While looking at a patch that introduced a compile-time warning
"‘pmc_core_dev_state_get’ defined but not used" (I sent a patch
for debugfs to fix it), I noticed that the same patch caused
it in intel_pmc_core also introduced a bogus run-time warning:
"PMC Core: debugfs register failed".

The problem is the IS_ERR_OR_NULL() check that as usual gets
things wrong: when CONFIG_DEBUGFS_FS is disabled,
debugfs_create_dir() fails with an error code, and we don't
need to warn about it, unlike the case in which it returns
NULL.

This reverts the driver to the previous state of not warning
about CONFIG_DEBUGFS_FS being disabled. I chose not to
restore the driver to making a runtime error in debugfs
fatal in pmc_core_probe().

Mika Westerberg bba6529ea0 platform/x86: intel_pmc_ipc: Do not create iTCO watchdog when WDAT table exists
ACPI WDAT table is the preferred way to use hardware watchdog over the
native iTCO_wdt. Windows only uses this table for its hardware watchdog
implementation so we should be relatively safe to trust it has been
validated by OEMs.

Prevent iTCO watchdog creation if we detect that there is an ACPI WDAT
table.

Deepa Dinamani c2050a454c fs: Replace current_fs_time() with current_time()
current_fs_time() uses struct super_block* as an argument.
As per Linus's suggestion, this is changed to take struct
inode* as a parameter instead. This is because the function
is primarily meant for vfs inode timestamps.
Also the function was renamed as per Arnd's suggestion.

Change all calls to current_fs_time() to use the new
current_time() function instead. current_fs_time() will be
deleted.

Added one additional parameter to thermal_zone_device_update() to provide
caller with an optional capability to specify reason.
Currently this event is used by user space governor to trigger different
processing based on event code. Also it saves an additional call to read
temperature when the event is received.
The following events are cuurently defined:
- Unspecified event
- New temperature sample
- Trip point violated

Oleksij Rempel b5643539b8 platform/x86: asus-wmi: Filter buggy scan codes on ASUS Q500A
Some revisions of the ASUS Q500A series have a keyboard related
issue which is reproducible only after Windows with installed ASUS
tools is started.

In this case the Linux side will have a blocked keyboard or
report incorrect or incomplete hotkey events.

To make Linux work properly again, a complete power down
(unplug power supply and remove battery) is needed.

Linux/atkbd after a clean start will get the following code on VOLUME_UP
key: {0xe0, 0x30, 0xe0, 0xb0}. After Windows, the same key will generate
this codes: {0xe1, 0x23, 0xe0, 0x30, 0xe0, 0xb0}. As result atkdb will
be confused by buggy codes.

This patch is filtering this buggy code out.

Giedrius Statkevičius 6f7e357bf1 platform/x86: asus-laptop: get rid of parse_arg()
parse_arg() duplicates the funcionality of kstrtoint() so use the latter
function instead. There is no funcionality change except that in the
case of input being too big -ERANGE will be returned instead of -EINVAL
which is not bad because -ERANGE makes more sense here. The check for
!count is already done by the sysfs core so no need to duplicate it
again. Also, add some minor corrections to error handling to accommodate
the change in return values (parse_arg returned count if everything
succeeded whereas kstrtoint returns 0 in the same situation)

Newer revisions of the ChromeOS EC add more events besides the keyboard

To keep backward compatibility, if the EC doesn't support MKBP event, we
fall back to the old MKBP key matrix host command.

Linus Torvalds 7e4dc77b28 Merge branch 'perf-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull perf updates from Ingo Molnar:
 "With over 300 commits it's been a busy cycle - with most of the work
  concentrated on the tooling side (as it should).

  The main kernel side enhancements were:

   - Add per event callchain limit: Recently we introduced a sysctl to
     tune the max-stack for all events for which callchains were
     requested:

       $ sysctl kernel.perf_event_max_stack
       kernel.perf_event_max_stack = 127

     Now this patch introduces a way to configure this per event, i.e.
     this becomes possible:

       $ perf record -e sched:*/max-stack=2/ -e block:*/max-stack=10/ -a

     allowing finer tuning of how much buffer space callchains use.

     This uses an u16 from the reserved space at the end, leaving
     another u16 for future use.

     There has been interest in even finer tuning, namely to control the
     max stack for kernel and userspace callchains separately.  Further
     discussion is needed, we may for instance use the remaining u16 for
     that and when it is present, assume that the sample_max_stack
     introduced in this patch applies for the kernel, and the u16 left
     is used for limiting the userspace callchain (Arnaldo Carvalho de
     Melo)

   - Optimize AUX event (hardware assisted side-band event) delivery
     (Kan Liang)

   - Rework Intel family name macro usage (this is partially x86 arch
     work) (Dave Hansen)

   - Refine and fix Intel LBR support (David Carrillo-Cisneros)

   - Add support for Intel 'TopDown' events (Andi Kleen)

   - Intel uncore PMU driver fixes and enhancements (Kan Liang)

   - ... other misc changes.

  Here's an incomplete list of the tooling enhancements (but there's
  much more, see the shortlog and the git log for details):

   - Support cross unwinding, i.e.  collecting '--call-graph dwarf'
     perf.data files in one machine and then doing analysis in another
     machine of a different hardware architecture.  This enables, for
     instance, to do:

       $ perf record -a --call-graph dwarf

     on a x86-32 or aarch64 system and then do 'perf report' on it on a
     x86_64 workstation (He Kuang)

   - Allow reading from a backward ring buffer (one setup via
     sys_perf_event_open() with perf_event_attr.write_backward = 1)
     (Wang Nan)

   - Finish merging initial SDT (Statically Defined Traces) support, see
     cset comments for details about how it all works (Masami Hiramatsu)

   - Support attaching eBPF programs to tracepoints (Wang Nan)

   - Add demangling of symbols in programs written in the Rust language
     (David Tolnay)

   - Add support for tracepoints in the python binding, including an
     example, that sets up and parses sched:sched_switch events,
     tools/perf/python/tracepoint.py (Jiri Olsa)

   - Introduce --stdio-color to set up the color output mode selection
     in 'annotate' and 'report', allowing emit color escape sequences
     when redirecting the output of these tools (Arnaldo Carvalho de
     Melo)

   - Add 'callindent' option to 'perf script -F', to indent the Intel PT
     call stack, making this output more ftrace-like (Adrian Hunter,
     Andi Kleen)

   - Allow dumping the object files generated by llvm when processing
     eBPF scriptlet events (Wang Nan)

   - Add stackcollapse.py script to help generating flame graphs (Paolo
     Bonzini)

   - Add --ldlat option to 'perf mem' to specify load latency for loads
     event (e.g. cpu/mem-loads/ ) (Jiri Olsa)

   - Tooling support for Intel TopDown counters, recently added to the
     kernel (Andi Kleen)"

We verify "u_cmd.outsize" and "u_cmd.insize" but we need to make sure
that those values have not changed between the two copy_from_user()
calls.  Otherwise it could lead to a buffer overflow.

Additionally, cros_ec_cmd_xfer() can set s_cmd->insize to a lower value.
We should use the new smaller value so we don't copy too much data to

João Paulo Rechi Vita 56a37a7200 asus-wmi: Add quirk_no_rfkill_wapf4 for the Asus X456UA
The Asus X456UA has an airplane-mode indicator LED and the WMI WLAN user
bit set, so asus-wmi uses ASUS_WMI_DEVID_WLAN_LED (0x00010002) to store
the wlan state, which has a side-effect of driving the airplane mode
indicator LED in an inverted fashion.

quirk_no_rfkill prevents asus-wmi from registering RFKill switches at
all for this laptop and allows asus-wireless to drive the LED through
the ASHS ACPI device.  This laptop already has a quirk for setting
WAPF=4, so use quirk_no_rfkill_wapf4, which both disables rfkill and
sets WAPF=4.

João Paulo Rechi Vita 6b7ff2af52 asus-wmi: Add quirk_no_rfkill for the Asus Z550MA
The Asus Z550MA has an airplane-mode indicator LED and the WMI WLAN user
bit set, so asus-wmi uses ASUS_WMI_DEVID_WLAN_LED (0x00010002) to store
the wlan state, which has a side-effect of driving the airplane mode
indicator LED in an inverted fashion. quirk_no_rfkill prevents asus-wmi
from registering RFKill switches at all for this laptop and allows
asus-wireless to drive the LED through the ASHS ACPI device.

João Paulo Rechi Vita a977e59c0c asus-wmi: Create quirk for airplane_mode LED
Some Asus laptops that have an airplane-mode indicator LED, also have
the WMI WLAN user bit set, and the following bits in their DSDT:

Scope (_SB)
{
  (...)
  Device (ATKD)
  {
    (...)
    Method (WMNB, 3, Serialized)
    {
      (...)
      If (LEqual (IIA0, 0x00010002))
      {
        OWGD (IIA1)
        Return (One)
      }
    }
  }
}

So when asus-wmi uses ASUS_WMI_DEVID_WLAN_LED (0x00010002) to store the
wlan state, it drives the airplane-mode indicator LED (through the call
to OWGD) in an inverted fashion: the LED is ON when airplane mode is OFF
(since wlan is ON), and vice-versa.

This commit creates a quirk to not register a RFKill switch at all for
these laptops, to allow the asus-wireless driver to drive the airplane
mode LED correctly through the ASHS ACPI device. It also adds a match to
that quirk for the Asus X555UB, which is affected by this problem.

João Paulo Rechi Vita 2c1a49c961 asus-wireless: Toggle airplane mode LED
In the ASHS device we have the HSWC method, which calls either OWGD or
OWGS, depending on its parameter:

	Device (ASHS)
	{
		Name (_HID, "ATK4002")  // _HID: Hardware ID
		Method (HSWC, 1, Serialized)
		{
			If ((Arg0 < 0x02))
			{
				OWGD (Arg0)
				Return (One)
			}
			If ((Arg0 == 0x02))
			{
				Local0 = OWGS ()
				If (Local0)
				{
					Return (0x05)
				}
				Else
				{
					Return (0x04)
				}
			}
			If ((Arg0 == 0x03))
			{
				Return (0xFF)
			}
			If ((Arg0 == 0x04))
			{
				OWGD (Zero)
				Return (One)
			}
			If ((Arg0 == 0x05))
			{
				OWGD (One)
				Return (One)
			}
			If ((Arg0 == 0x80))
			{
				Return (One)
			}
		}
		Method (_STA, 0, NotSerialized)  // _STA: Status
		{
			If ((MSOS () >= OSW8))
			{
				Return (0x0F)
			}
			Else
			{
				Return (Zero)
			}
		}
	}

On the Asus laptops that do not have an airplane mode LED, OWGD has an
empty implementation and OWGS simply returns 0. On the ones that have an
airplane mode LED these methods have the following implementation:

	Method (OWGD, 1, Serialized)
	{
		SGPL (0x0203000F, Arg0)
		SGPL (0x0203000F, Arg0)
	}

	Method (OWGS, 0, Serialized)
	{
		Store (RGPL (0x0203000F), Local0)
		Return (Local0)
	}

Where OWGD(1) sets the airplane mode LED ON, OWGD(0) set it off, and
OWGS() returns its state.

This commit exposes the airplane mode indicator LED to userspace under
the name asus-wireless::airplane, so it can be driven according to
userspace's policy.

Michał Kępień 1879e69f4c fujitsu-laptop: Support touchpad toggle hotkey on Skylake-based models
Haswell-based Fujitsu laptops (Lifebook E734/E744/E754) have a touchpad
toggle hotkey (Fn+F4) which is handled transparently to the operating
system: while an ACPI notification is sent to FUJ02B1 when Fn+F4 is
pressed, touchpad state is properly toggled without any explicit support
for this operation in fujitsu-laptop.

Skylake-based models (Lifebook E736/E746/E756) also have that hotkey,
but the touchpad is not toggled transparently to the operating system.
When Fn+F4 is pressed, an ACPI notification is sent to FUJ02E3.  A
subsequent call to S000 (FUNC_RFKILL) can be used to determine whether
the touchpad toggle hotkey was pressed so that an input event can be
sent to userspace.

Relevant ACPI code:

    Method (_L21, 0, NotSerialized)
    {
        ...
        If (AHKF)
        {
            Notify (\_SB.FEXT, 0x80)
        }
        ...
    }

    Method (S000, 3, Serialized)
    {
        Name (_T_0, Zero)
        Local0 = Zero
        While (One)
        {
            _T_0 = Arg0
            If (_T_0 == Zero)
            {
                Local0 |= 0x04000000
                Local0 |= 0x02000000
                Local0 |= 0x00020000
                Local0 |= 0x0200
                Local0 |= 0x0100
                Local0 |= 0x20
            }
            ElseIf (_T_0 == One)
            {
                ...
                If (AHKF & 0x08)
                {
                Local0 |= 0x04000000
                AHKF ^= 0x08
                }
                ...
            } ...
            Break
        }
        Return (Local0)
    }

Pressing Fn+F4 raises GPE 0x21 and sets bit 3 in AHKF.  This in turn
results in bit 26 being set in the value returned by FUNC_RFKILL called
with 1 as its first argument.  On Skylake-based models, bit 26 is also
set in the value returned by FUNC_RFKILL called with 0 as its first
argument (this value is saved in fujitsu_hotkey->rfkill_supported upon
module initialization), which suggests that this bit is set on models
which do not handle touchpad toggling transparently to the operating
system.

Note that bit 3 is cleared in AHKF once FUNC_RFKILL is called with 1 as
its first argument, which requires fujitsu-laptop to handle this hotkey
in a different manner than the other, GIRB-based hotkeys: two input
events (press and release) are immediately sent once Fn+F4 is pressed.

Pali Rohár e075b3c898 dell-wmi: Generate one sparse keymap for all machines
This patch reworks code for generating sparse keymap and processing WMI
events. It unifies procedure for generating sparse keymap and also unifies
big switch code for processing WMI events of different types. After this
patch dell-wmi driver does not differ between "old" and "new" hotkey type.

It constructs sparse keymap table with all WMI codes. It is because on some
laptops (e.g. Dell Latitude E6440) ACPI/firmware send both event types (old
and new).

Each WMI code in sparse keymap table is prefixed by 16bit event type, so it
does not change functionality on laptops with "old" hotkey support (those
without scancodes in DMI).

This allow us to distinguish between same WMI codes with different types in
sparse keymap. Thanks to this WMI events of type 0x0011 were moved from big
switch into sparse keymap table too.

This patch also fixes possible bug in parsing WMI event buffer introduced
in commit 5ea2559726 ("dell-wmi: Add support for new Dell systems"). That
commit changed buffer type from int* to u16* without fixing code. More at:

Rajneesh Bhardwaj b740d2e923 platform/x86: Add PMC Driver for Intel Core SoC
This patch adds the Power Management Controller driver as a PCI driver
for Intel Core SoC architecture.

This driver can utilize debugging capabilities and supported features
as exposed by the Power Management Controller.

Please refer to the below specification for more details on PMC features.
http://www.intel.in/content/www/in/en/chipsets/100-series-chipset-datasheet-vol-2.html

The current version of this driver exposes SLP_S0_RESIDENCY counter.
This counter can be used for detecting fragile SLP_S0 signal related
failures and take corrective actions when PCH SLP_S0 signal is not
asserted after kernel freeze as part of suspend to idle flow
(echo freeze > /sys/power/state).

Intel Platform Controller Hub (PCH) asserts SLP_S0 signal when it
detects favorable conditions to enter its low power mode. As a
pre-requisite the SoC should be in deepest possible Package C-State
and devices should be in low power mode. For example, on Skylake SoC
the deepest Package C-State is Package C10 or PC10. Suspend to idle
flow generally leads to PC10 state but PC10 state may not be sufficient
for realizing the platform wide power potential which SLP_S0 signal
assertion can provide.

SLP_S0 signal is often connected to the Embedded Controller (EC) and the
Power Management IC (PMIC) for other platform power management related
optimizations.

In general, SLP_S0 assertion == PC10 + PCH low power mode + ModPhy Lanes
power gated + PLL Idle.

As part of this driver, a mechanism to read the SLP_S0_RESIDENCY is exposed
as an API and also debugfs features are added to indicate SLP_S0 signal
assertion residency in microseconds.

echo freeze > /sys/power/state
wake the system

Gabriele Mazzotta ff8651237f dell-rbtn: Ignore ACPI notifications if device is suspended
Some BIOSes unconditionally send an ACPI notification to RBTN when the
system is resuming from suspend. This makes dell-rbtn send an input
event to userspace as if a function key was pressed. Prevent this by
ignoring all the notifications received while the device is suspended.

Linus Torvalds 1eccc6e152 This is the bulk of GPIO changes for kernel cycle v4.7:
Core infrastructural changes:
 
 - Support for natively single-ended GPIO driver stages. This
   means that if the hardware has registers to configure open
   drain or open source configuration, we use that rather than
   (as we did before) try to emulate it by switching the line
   to an input to get high impedance. This is also documented
   throughly in Documentation/gpio/driver.txt for those of you
   who did not understand one word of what I just wrote.
 
 - Start to do away with the unnecessarily complex and
   unitelligible ARCH_REQUIRE_GPIOLIB and
   ARCH_WANT_OPTIONAL_GPIOLIB, another evolutional artifact from
   the time when the GPIO subsystem was unmaintained. Archs can
   now just select GPIOLIB and be done with it, cleanups to
   arches will trickle in for the next kernel. Some minor archs
   ACKed the changes immediately so these are included in this
   pull request.
 
 - Advancing the use of the data pointer inside the GPIO device
   for storing driver data by switching the PowerPC, Super-H
   Unicore and a few other subarches or subsystem drivers in
   ALSA SoC, Input, serial, SSB, staging etc to use it.
 
 - The initialization now reads the input/output state of the
   GPIO lines, so that each GPIO descriptor knows - if this
   callback is implemented - whether the line is input or
   output. This also reflects nicely in userspace "lsgpio".
 
 - It is now possible to name GPIO producer names, line names,
   from the device tree. (Platform data has been supported for
   a while.) I bet we will get a similar mechanism for ACPI
   one of those days. This makes is possible to get sensible
   producer names for e.g. GPIO rails in "lsgpio" in userspace.
 
 New drivers:
 
 - New driver for the Loongson1.
 
 - The XLP driver now supports Broadcom Vulcan ARM64.
 
 - The IT87 driver now supports IT8620 and IT8628.
 
 - The PCA953X driver now supports Galileo Gen2.
 
 Driver improvements:
 
 - MCP23S08 was switched to use the gpiolib irqchip helpers and
   now also suppors level-triggered interrupts.
 
 - 74x164 and RCAR now supports the .set_multiple() callback
 
 - AMDPT was converted to use generic GPIO.
 
 - TC3589x, TPS65218, SX150X, F7188X, MENZ127, VX855, WM831X, WM8994
   support the new single ended callback for open drain
   and in some cases open source.
 
 - Implement the .get_direction() callback for a few more drivers
   like PL061, Xgene.
 
 Cleanups:
 
 - Paul Gortmaker combed through the drivers and de-modularized
   those who are not really modules.
 
 - Move the GPIO poweroff DT bindings to the power subdir where
   they belong.
 
 - Rename gpio-generic.c to gpio-mmio.c, which is much more to the
   point. That's what it is handling, nothing more, nothing less.

Merge tag 'gpio-v4.7-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio

Pull GPIO updates from Linus Walleij:
 "This is the bulk of GPIO changes for kernel cycle v4.7:

  Core infrastructural changes:

   - Support for natively single-ended GPIO driver stages.

     This means that if the hardware has registers to configure open
     drain or open source configuration, we use that rather than (as we
     did before) try to emulate it by switching the line to an input to
     get high impedance.

     This is also documented throughly in Documentation/gpio/driver.txt
     for those of you who did not understand one word of what I just
     wrote.

   - Start to do away with the unnecessarily complex and unitelligible
     ARCH_REQUIRE_GPIOLIB and ARCH_WANT_OPTIONAL_GPIOLIB, another
     evolutional artifact from the time when the GPIO subsystem was
     unmaintained.

     Archs can now just select GPIOLIB and be done with it, cleanups to
     arches will trickle in for the next kernel.  Some minor archs ACKed
     the changes immediately so these are included in this pull request.

   - Advancing the use of the data pointer inside the GPIO device for
     storing driver data by switching the PowerPC, Super-H Unicore and
     a few other subarches or subsystem drivers in ALSA SoC, Input,
     serial, SSB, staging etc to use it.

   - The initialization now reads the input/output state of the GPIO
     lines, so that each GPIO descriptor knows - if this callback is
     implemented - whether the line is input or output.  This also
     reflects nicely in userspace "lsgpio".

   - It is now possible to name GPIO producer names, line names, from
     the device tree.  (Platform data has been supported for a while).
     I bet we will get a similar mechanism for ACPI one of those days.
     This makes is possible to get sensible producer names for e.g.
     GPIO rails in "lsgpio" in userspace.

  New drivers:

   - New driver for the Loongson1.

   - The XLP driver now supports Broadcom Vulcan ARM64.

   - The IT87 driver now supports IT8620 and IT8628.

   - The PCA953X driver now supports Galileo Gen2.

  Driver improvements:

   - MCP23S08 was switched to use the gpiolib irqchip helpers and now
     also suppors level-triggered interrupts.

   - 74x164 and RCAR now supports the .set_multiple() callback

   - AMDPT was converted to use generic GPIO.

   - TC3589x, TPS65218, SX150X, F7188X, MENZ127, VX855, WM831X, WM8994
     support the new single ended callback for open drain and in some
     cases open source.

   - Implement the .get_direction() callback for a few more drivers like
     PL061, Xgene.

  Cleanups:

   - Paul Gortmaker combed through the drivers and de-modularized those
     who are not really modules.

   - Move the GPIO poweroff DT bindings to the power subdir where they
     belong.

   - Rename gpio-generic.c to gpio-mmio.c, which is much more to the
     point.  That's what it is handling, nothing more, nothing less"

Clinton Sprain d940f3065c platform/chrome: cros_ec_lightbar - use name instead of ID to hide lightbar attributes
Lightbar attributes are hidden if the ID of the device is not 0 (the
assumption being that 0 = cros_ec = might have a lightbar, 1 = cros_pd =
hide); however, sometimes these devices get IDs 1 and 2 (or something
else) instead of IDs 0 and 1. This prevents the lightbar attributes from
appearing when they should.

Proposed change is to instead check whether the name assigned to the
device is CROS_EC_DEV_NAME (true for cros_ec, false for cros_pd).

Gwendal Grignou 5d749d0bbe platform/chrome: cros_ec_dev - Fix security issue
Prevent memory scribble by checking that ioctl buffer size parameters
are sane.
Without this check, on 32 bits system, if .insize = 0xffffffff - 20 and
.outsize the amount to scribble, we would overflow, allocate a small
amounts and be able to write outside of the malloc'ed area.
Adding a hard limit allows argument checking of the ioctl. With the
current EC, it is expected .insize and .outsize to be at around 512 bytes
or less.

Commit 52cbae0127 ("toshiba_acpi: Change default Hotkey enabling value")
changed the hotkeys enabling value, as it was the same value Windows uses,
however, it turns out that the value tells the EC that the driver will now
take care of the hardware events like the physical RFKill switch or the
pointing device toggle button.

This patch reverts such commit by changing the default hotkey enabling
value to 0x09, which enables hotkey events only, making the hardware
buttons working again.

Michał Kępień 4f62568c1f fujitsu-laptop: Support radio LED
Lifebook E734/E744/E754 has a LED which the manual calls "radio
components indicator".  It should be lit when any radio transmitter is
enabled.  Its state can be read and set using ACPI (FUNC interface,
RFKILL method).

Since the Lifebook E734/E744/E754 only has a button (as compared to a
slider) for enabling/disabling radio transmitters, I believe the LED in
question is meant to indicate whether all radio transmitters are
currently on or off.  However, pressing the radio toggle button does not
automatically change the hardware state of the transmitters: it looks
like this machine relies on soft rfkill.

As for detecting whether the LED is present on a given machine, I had to
resort to educated guesswork.  I assumed this LED is present on all
devices which have a radio toggle button instead of a slider.  My
Lifebook E744 holds 0x01010001 in BTNI.  By comparing the bits and
buttons with those of a Lifebook E8420 (BTNI=0x000F0101, has a slider),
I put my money on bit 24 as the indicator of the radio toggle button
being present.  Furthermore, bit 24 is also clear on the S7020 which
does not have the toggle button or an RF LED.

Figuring out how the LED is controlled was more deterministic as all it
took was decompiling the DSDT and taking a look at method S000 (the
RFKILL method of the FUNC interface).

The LED control method implemented here is unsuitable for use with
"heavy" LED triggers, like phy0rx.  Once blinking frequency achieves a
certain level, the system hangs.

Linus Torvalds cb107161df Convert straggling drivers to new six-argument get_user_pages()
Commit d4edcf0d56 ("mm/gup: Switch all callers of get_user_pages() to
not pass tsk/mm") switched get_user_pages() callers to the simpler model
where they no longer pass in the thread and mm pointer.  But since then
we've merged changes to a few drivers that re-introduce use of the old
interface.  Let's fix them up.

They continued to work fine (thanks to the truly disgusting macros

Maciej S. Szmigiero fffcad87d4 hp-wmi: Remove GPS rfkill support via pre-2009 interface
GPS rfkill support via pre-2009 WMI interface uses hp_wmi_get_sw_state()
and hp_wmi_get_hw_state() to query its current hard and soft block state,
respectively.

In hp_wmi_get_sw_state() a mask is calculated which bit should be checked
in an int value returned by firmware to get current block state: 0x200 <<
(r * 8) which with r being 3 for GPS results in overflow and mask of zero.
The same goes for hp_wmi_get_hw_state().

This effectively means that GPS rfkill on this WMI interface is considered
always both hard and soft blocked.

Unfortunately, later when rfkill subsystem calls hp_wmi_set_block() to sync
this block to hardware firmware at least on my old nc6400 gets confused and
sets both hard and soft blocks on WiFi and BT.

This happens for example on hp-wmi module load.

Since due to overflow described above it is dubious that this ever worked
correctly and HP laptops with modems having GPS support seem to all have
been released well past year 2009 let's just remove GPS rfkill support via
pre-2009 WMI interface.

Maciej S. Szmigiero c7805e5459 hp-wmi: fix unregister order in hp_wmi_rfkill_setup() once again
rfkill registration order in hp_wmi_rfkill_setup() is:
1) WiFi,
2) BT,
3) WWAN,
5) GPS.

Unregistration when cleaning up on error return should happen in reverse
order.

This means that: If BT rfkill fails to be allocated we possibly need to
first unregister WiFi rfkill before destroying it.

The same goes with (WWAN, BT) and (GPS, WWAN) pairs.

Also, if WWAN rfkill fails to register we need to (possibly) unregister BT
not the GPS one.  And if GPS rfkill fails to register we need to unregister
WWAN not the BT one.

We never need to unregister GPS rfkill here since if GPS rfkill
registration succeeds this function returns without error so no cleanup is
necessary.

Similarly to Dell Vostro V131, Dell Inspiron M5110 also requires an
SMBIOS request to be issued in order for WMI events to be generated and
does not raise an i8042 interrupt when the Dell Instant Launch hotkey is

On models on which an SMBIOS request needs to be issued in order for WMI
events to be generated, pressing the Dell Instant Launch hotkey does not
raise an i8042 interrupt - only a WMI event is generated (0xe025 on Dell
Vostro V131).  As that WMI event is the only way the kernel will be
notified about pressing the Dell Instant Launch hotkey on such machines,
the relevant keymap entry has to be changed to a KE_KEY one.  However,
the same WMI event should still be ignored on machines which do not
require an SMBIOS request for enabling WMI, so filter it conditionally
in dell_wmi_process_key().

On some laptop models (e.g. Dell Vostro V131), WMI events are not
generated until a specific SMBIOS request is issued to register an event
listener [1].  As there seems to be no ACPI method or SMBIOS request to
determine without possible side effects whether a given machine needs to
issue this SMBIOS request in order to receive WMI events, DMI matching
is used to whitelist the models which need it.

Paul Gortmaker f52ab44fb7 platform/x86: Make intel_scu_ipc explicitly non-modular
The Kconfig currently controlling compilation of this code is:

drivers/platform/x86/Kconfig:config INTEL_SCU_IPC
drivers/platform/x86/Kconfig:   bool "Intel SCU IPC Support"

...meaning that it currently is not being built as a module by anyone.

Lets remove the modular code that is essentially orphaned, so that
when reading the driver there is no doubt it is builtin-only.

We explicitly disallow a driver unbind, since that doesn't have a
sensible use case anyway, and it allows us to drop the ".remove"
code for non-modular drivers.

Since module_pci_driver() uses the same init level priority as
builtin_pci_driver() the init ordering remains unchanged with
this commit.

Also note that MODULE_DEVICE_TABLE is a no-op for non-modular code.

We don't replace module.h with init.h since the file already has that.

We also delete the MODULE_LICENSE tag etc. since all that information
is already contained at the top of the file in the comments.

[  284.446467] pmc-ipc-plat INT34D2:00: IPC timed out, TS=0x4, CMD=0x200ff

This is because before the opregion driver could send IPC1 commands,
the PMC_IPC irq is already suspended. Which makes the IPC command to
timeout.

Solution: register pmc_ipc irq as IRQF_NO_SUSPEND

Andy Lutomirski a464afb958 dell-wmi: Support new hotkeys on the XPS 13 9350 (Skylake)
The XPS 13 9350 sends WMI keypress events that aren't enumerated in
the DMI table.  Add a table listing them.  To avoid breaking things
that worked before, these un-enumerated hotkeys won't be used if the
DMI table maps them to something else.

FWIW, it appears that the DMI table may be a legacy thing and we
might want to rethink how we handle events in general.  As an
example, a whole lot of things map to KEY_PROG3 via the DMI table.

This doesn't send keypress events for any of the new events.  They
appear to all be handled by other means (keyboard illumination is
handled automatically and rfkill is handled by intel-hid).

Andy Lutomirski b13de7019c dell-wmi: Clean up hotkey table size check
Checking the table for a minimum size of 7 bytes makes no sense: any valid
hotkey table has a size that's a multiple of 4.

Clean this up: replace the hardcoded header length with a sizeof and
change the check to ignore an empty hotkey table.  The only behavior
change is that a 7-byte table (which is nonsensical) will now be
treated as absent instead of as valid but empty.

Andy Lutomirski 18b6f80f50 dell-wmi: Stop storing pointers to DMI tables
The dmi_walk function maps the DMI table, walks it, and unmaps it.
This means that the dell_bios_hotkey_table that find_hk_type stores
points to unmapped memory by the time it gets read.

I've been able to trigger crashes caused by the stale pointer a
couple of times, but never on a stock kernel.

Fix it by generating the keymap in the dmi_walk callback instead of
storing a pointer.

Lukas Wunner f798d96528 apple-gmux: Add switch_ddc support
Originally by Seth Forshee <seth.forshee@canonical.com>, 2012-10-04:
    The gmux allows muxing the DDC independently from the display, so
    support this functionality. This will allow reading the EDID for the
    inactive GPU, fixing issues with machines that either don't have a
    VBT or have invalid mode data in the VBT.

Modified by Lukas Wunner <lukas@wunner.de>, 2015-04 - 2015-12:
    Change semantics of ->switch_ddc handler callback to return previous
    DDC owner. Original version tried to determine previous DDC owner
    with find_active_client() in vga_switcheroo but this fails if the
    inactive client registers before the active client.

    v2.4: Retain semantics of ->switchto handler callback to switch all
          pins, including DDC (Daniel Vetter)

    v4:   Advertise ->switch_ddc handler callback only on the pre-retina
          Macbook Pro. The retina uses eDP instead of LVDS and gmux no
          longer does the muxing itself but merely controls an external
          mux. That mux is incapable of switching the AUX channel

Lukas Wunner 3e46304e74 apple-gmux: Track switch state
gmux has 3 switch registers:

* GMUX_PORT_SWITCH_DISPLAY switches the panel
* GMUX_PORT_SWITCH_DDC switches the panel's DDC lines
  (only on pre-retinas; on retinas this is a no-op)
* GMUX_PORT_SWITCH_EXTERNAL switches the external DP port(s)
  (only on models without Thunderbolt, i.e. introduced before 2011;
  those with Thunderbolt switch only HPD/AUX, not the main link)

Currently we switch all 3 registers in unison.

gmux does not preserve the switch state during suspend, so we currently
read GMUX_PORT_SWITCH_DISPLAY before suspend and restore all 3 registers
to this value on resume.

With the upcoming ->switch_ddc callback, GMUX_PORT_SWITCH_DDC may
temporarily contain a different value than the other 2 registers.
If we happen to suspend at this moment, we'll write an incorrect
value to GMUX_PORT_SWITCH_DDC on resume.

Also, on models with Thunderbolt the integrated GPU is unable to drive
the external DP port(s), so we want to keep GMUX_PORT_SWITCH_EXTERNAL
permanently switched to the discrete GPU on those machines.

Consequently we can no longer assume that GMUX_PORT_SWITCH_DISPLAY
represents the correct value for all 3 registers on suspend.

Track the state of all 3 registers: Add gmux_read_switch_state() and
gmux_write_switch_state(). Instead of reading the switch state on
every suspend, read it once on driver initialization so that we know
the current switch state all the time. (This allows us to use some
optimizations and shortcuts, e.g. we can skip switching DDC if we
know that it's already switched to the requested GPU.) Change the
->switchto callback to use gmux_write_switch_state().

Lukas Wunner 156d7d4120 vga_switcheroo: Add handler flags infrastructure
Allow handlers to declare their capabilities and allow clients to
obtain that information. So far we have these use cases:

* If the handler is able to switch DDC separately, clients need to
  probe EDID with drm_get_edid_switcheroo(). We should allow them
  to detect a capable handler to ensure this function only gets
  called when needed.

* Likewise if the handler is unable to switch AUX separately, the active
  client needs to communicate link training parameters to the inactive
  client, which may then skip the AUX handshake and set up its output
  with these pre-calibrated values (DisplayPort specification v1.1a,
  section 2.5.3.3). Clients need a way to recognize such a situation.

The flags for the radeon_atpx_handler and amdgpu_atpx_handler are
initially set to 0, this can later on be amended with
  handler_flags |= VGA_SWITCHEROO_CAN_SWITCH_DDC;
when a ->switch_ddc callback is added.

Yu Ning 4f42071c94 goldfish_pipe: Pass physical addresses to the device if supported
For reading and writing guest user space buffers, currently the kernel
sends the guest virtual address of the buffer to the pipe device. This
virtual address has to be first converted to a guest physical address.
Doing this translation on the QEMU side is inefficient and requires
additional handling when KVM is enabled, whose implementation would
either incur intrusive changes to QEMU's KVM support code or suffer
from poor performance, see commit 08c7228c50f8 ("x86-kvm: only sync
SREGS when doing address translation") of $AOSP/external/qemu for
details, and thus should be avoided if possible.

There is a TODO comment in hw/misc/android_pipe.c in the new Android
emulator source tree ($AOSP/external/qemu-android) which requests that
the translation be done on the kernel side and that physical addresses
be passed to the device instead of virtual ones. Once the QEMU-side
implementation is done, the kernel will need to support both the new
paddr-based pipe device and the old vaddr-based one (which will
continue to be used by the classic emulator). This patch achieves that
by leveraging the device version register available in the new device.

See https://android-review.googlesource.com/128280 for the QEMU-side
patch.

In addition, use the mmap semaphore (in read mode) to safeguard the
call to get_user_pages().

Christoffer Dall 2f3be88237 goldfish_pipe: Pin pages to memory while copying and other cleanups
The existing code had a troubling TODO statement concerning the fact
that it just did a check if the page that the QEMU backend was going to
read from / write to was there before the call to the QEMU backend and
then relying on the fact that the page stayed around, even in a
preemptible SMP kernel.  Obviously the page could go away or be
reassigned, and strange things may happen.

Further, writes were not tracked, so any use of COW or KSM-like
features would break completely.  Probably that was never used by adbd
(the only current active user of the pipe), but could prove much more
dangerous for the GPU passthrough mechanism.

Instead, use get_user_pages() as the comment suggested and cleanup the
error path and add the set_page_dirt() call on a successful read
operation.

Also clarify the count used to return from successful read/write calls
and use Linux style commentary in various places of the file.

Note: The "just ignore error and return whatever we read so far" error
handling is really quite horrific.  I cannot change it without a more
careful study of all user space ABIs reliance on this 'feature'.

 "This includes fixes on top of the previous batch of PM+ACPI updates
  and some new material as well.

  From the new material perspective the most significant are the driver
  core changes that should allow USB devices to stay suspended over

  already beforehand.  Apart from that, ACPICA is updated to upstream
  revision 20160108 (cosmetic mostly, but including one fixup on top of
  the previous ACPICA update) and there are some devfreq updates the
  didn't make it before (due to timing).

  A few recent regressions are fixed, most importantly in the cpuidle
  menu governor and in the ACPI backlight driver and some x86 platform
  drivers depending on it.

  Some more bugs are fixed and cleanups are made on top of that.

Souvik Kumar Chakravarty 9d16b482b0 platform:x86: Add Intel telemetry platform driver
Telemetry platform driver implements the telemetry interfaces.
Currently it supports ApolloLake. It uses the PUNIT and PMC IPC
interfaces to configure the telemetry samples to read.
The samples are read from a Secure SRAM region.

Souvik Kumar Chakravarty 378f956e3f platform/x86: Add Intel Telemetry Core Driver
Intel PM Telemetry is a software mechanism via which various SoC
PM and performance related parameters like PM counters, firmware
trace verbosity, the status of different devices inside the SoC, etc.
can be monitored and analyzed. The different samples that may be
monitored can be configured at runtime via exported APIs.

This patch adds the telemetry core driver that implements basic
exported APIs.

Pali Rohár 481fe5be82 dell-wmi: Process only one event on devices with interface version 0
BIOS/ACPI on devices with WMI interface version 0 does not clear buffer
before filling it. So next time when BIOS/ACPI send WMI event which is
smaller as previous then it contains garbage in buffer from previous event.

BIOS/ACPI on devices with WMI interface version 1 clears buffer and
sometimes send more events in buffer at one call.

Since commit 83fc44c32a ("dell-wmi: Update code for processing WMI
events") dell-wmi process all events in buffer (and not just first).

To prevent reading garbage from the buffer we process only the first
event on devices with WMI interface version 0.

Pali Rohár 595773a493 dell-wmi: Check if Dell WMI descriptor structure is valid
After examining existing DSDT ACPI tables of more laptops and looking
into Dell WMI document mentioned in ML dicussion archived at
http://www.spinics.net/lists/platform-driver-x86/msg07220.html we will
parse and check WMI descriptor if contains expected data. It is because
WMI descriptor contains interface version number and it is needed to
know in next commit.
