Pull thermal managament updates from Zhang Rui:
- Enhance thermal "userspace" governor to export the reason when a
thermal event is triggered and delivered to user space. From Srinivas
Pandruvada
- Introduce a single TSENS thermal driver for the different versions of
the TSENS IP that exist, on different qcom msm/apq SoCs'. Support for
msm8916, msm8960, msm8974 and msm8996 families is also added. From
Rajendra Nayak
- Introduce hardware-tracked trip points support to the device tree
thermal sensor framework. The framework supports an arbitrary number
of trip points. Whenever the current temperature is changed, the trip
points immediately below and above the current temperature are found,
driver callback is invoked to program the hardware to get notified
when either of the two trip points are triggered. Hardware-tracked
trip points support for rockchip thermal driver is also added at the
same time. From Sascha Hauer, Caesar Wang
- Introduce a new thermal driver, which enables TMU (Thermal Monitor
Unit) on QorIQ platform. From Jia Hongtao
- Introduce a new thermal driver for Maxim MAX77620. From Laxman

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().

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.

current_time() function instead. current_fs_time() will be

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.

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)

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
the 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.

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.

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.

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.
