Arnd Bergmann 7f95de5e4a Reset controller changes for v4.17, part 2
This tag contains reset lookup support, similar to pwm lookups, for legacy
 non-DT platforms, a few new reset controls and a Kconfig fix for uniphier
 SoCs, as well as a new driver for the STM32MP1 peripheral reset controller.
 
 The reset lookups are merged from a separate, immutable branch, that may
 also be merged into the davinci tree.

01d675f159 ARM: shmobile: rcar-gen2: Add watchdog support
 58adf1ba0d ARM: shmobile: Add watchdog support
 
 * SoC
   - Identify R-Car V3H (r8a77980) and M3N (r8a77965)
 
   - Enable R-Car Gen2 regulator quirk for Stout board with H3 (r8a7790) SoC
 
     Marek Vaust says "Regulator setup is suboptimal on H2 Stout too. The
     Stout newly has two DA9210 regulators, so the quirk is extended to
     handle another DA9210 at i2c address 0x70."
 
   - Add watchdog support
 
     This is the SoC portion of the following solution. It is not yet
     enabled in DT as it is not functional without clock dependencies
     in place.
 
     Fabrizio Castro says "this series has been around for some time as RFC,
     and it has collected useful comments from the community along the way.
     The solution proposed by this patch set works for most R-Car Gen2 and
     RZ/G1 devices, but not all of them. We now know that for some R-Car
     Gen2 early revisions there is no proper software fix. Anyway, no
     product has been built around early revisions, but development boards
     mounting early revisions (basically prototypes) are still out there.
     As a result, this series isn't enabling the internal watchdog on R-Car
     Gen2 boards, developers may enable it in board specific device trees if
     needed.  This series has been tested by me on the iwg20d, iwg22d,
     Lager, Alt, and Koelsch boards.
 
    The problem
    ===========
    To deal with SMP on R-Car Gen2 and RZ/G1, we install a reset vector to
    ICRAM1 and we program the [S]BAR registers so that when we turn ON the
    non-boot CPUs they are redirected to the reset vector installed by Linux
    in ICRAM1, and eventually they continue the execution to RAM, where the
    SMP bring-up code will take care of the rest.  The content of the [S]BAR
    registers survives a watchdog triggered reset, and as such after the
    watchdog fires the boot core will try and execute the SMP bring-up code
    instead of jumping to the bootrom code.
 
    The fix
    =======
    The main strategy for the solution is to let the reset vector decide if
    it needs to jump to shmobile_boot_fn or to the bootrom code.  In a
    watchdog triggered reset scenario, since the [S]BAR registers keep their
    values, the boot CPU will jump into the newly designed reset vector, the
    assembly routine will eventually test WOVF (a bit in register RWTCSRA
    that indicates if the watchdog counter has overflown, the value of this
    bit gets retained in this scenario), and jump to the bootrom code which
    will in turn load up the bootloader, etc.  When bringing up SMP or using
    CPU hotplug, the reset vector will jump to shmobile_boot_fn instead."

    memory after kernel init."

Stephen Boyd b9c725ed73 dt-bindings: gpio: Add a gpio-reserved-ranges property
Some qcom platforms make some GPIOs or pins unavailable for use
by non-secure operating systems, and thus reading or writing the
registers for those pins will cause access control issues.
Introduce a DT property to describe the set of GPIOs that are
available for use so that higher level OSes are able to know what
pins to avoid reading/writing.

Icenowy Zheng c8a8309049 pinctrl: sunxi: add support for the Allwinner H6 main pin controller
The Allwinner H6 SoC has two pin controllers, one main controller
(called CPUX-PORT in user manual) and one controller in CPUs power
domain (called CPUS-PORT in user manual).

This commit introduces support for the main pin controller on H6.

The pin bank A and B are not wired out and hidden from the SoC's
documents, however it's shown that the "ATE" (an AC200 chip
co-packaged with the H6 die) is connected to the main SoC die via these
pin banks. The information about these banks is just copied from the BSP
pinctrl driver, but re-formatted to fit the mainline pinctrl driver
format. The GPIO functions are dropped, as they're impossible to use --
except a GPIO&IRQ only pin (PB20) which might be the IRQ of ATE.

====================
100GbE Intel Wired LAN Driver Updates 2018-03-26

This patch series adds the ice driver, which will support the Intel(R)
E800 Series of network devices.

This is the first phase in the release of this driver where we implement
basic transmit and receive. The idea behind the multi-phase release is to
aid in code review as well as testing. Subsequent phases will implement
advanced features (like SR-IOV, tunnelling, flow director, QoS, etc.) that
build upon the previous phase(s). Each phase will be submitted as a patch
series.

Suzuki K Poulose ece1397cbc arm64: Add work around for Arm Cortex-A55 Erratum 1024718
Some variants of the Arm Cortex-55 cores (r0p0, r0p1, r1p0) suffer
from an erratum 1024718, which causes incorrect updates when DBM/AP
bits in a page table entry is modified without a break-before-make

on the affected cores. The hardware Access Flag management features
is not affected. There are some other cores suffering from this
errata, which could be added to the midr_list to trigger the work
around.

Ever since commit 3a06c7ac24 ("posix-clocks: Remove interval timer

posix timers has been removed.  In addition it will probably never

Use the "reg" property to specify the processor's local APIC ID instead of
setting it to the CPU node index in Device Tree.

Local APIC ID is assigned by hardware and visible in the APIC ID register.
Some processor models allow APIC ID to be changed by software, but CPUID
instruction executed with %eax = 0x0b always returns the initial ID in %edx.

Local APIC ID does not match the node index in many systems.

Masahiro Yamada 911a91c39c kconfig: rename silentoldconfig to syncconfig
As commit cedd55d49d ("kconfig: Remove silentoldconfig from help
and docs; fix kconfig/conf's help") mentioned, 'silentoldconfig' is a
historical misnomer.  That commit removed it from help and docs since
it is an internal interface.  If so, it should be allowed to rename
it to something more intuitive.  'syncconfig' is the one I came up
with because it updates the .config if necessary, then synchronize
include/generated/autoconf.h and include/config/* with it.

You should not manually invoke 'silentoldcofig'.  Display warning if
used in case existing scripts are doing wrong.

Masahiro Yamada bd0f98eba6 kbuild: remove internally used LDFLAGS_vmlinux from kbuild.txt
Documentation/kbuild/makefiles.txt lists variables used in Makefile
whereas Documentation/kbuild/kbuild.txt describes user assignable
parameters given via environments or the command line.

The top Makefile and arch/*/Makefile accumulate proper linker flags to
LDFLAGS_vmlinux.  So, users can not override it from the command line.
Generally, per-file options are not supposed to be user-assignable.
Remove the misleading entry from kbuild.txt.

If we need a way to append user-specific flags for linking the kernel,
LDFLAGS_KERNEL would be a consistent choice because we already expose
LDFLAGS_MODULE counter-part to users.

Documentation/kbuild/makefiles.txt lists variables used in Makefile
whereas Documentation/kbuild/kbuild.txt describes user assignable
parameters given via environments or the command line.

LDFLAGS_MODULE is a command line interface, so it should be dropped
from makefiles.txt.

Some lines below in this file, it is clearly explained that
KBUILD_LDFLAGS_MODULE is the right one for the internal use:

    KBUILD_LDFLAGS_MODULE   Options for $(LD) when linking modules

        $(KBUILD_LDFLAGS_MODULE) is used to add arch-specific options
        used when linking modules. This is often a linker script.
        From commandline LDFLAGS_MODULE shall be used (see kbuild.txt).

Then, kbuild.txt explains LDFLAGS_MODULE, like follows:

    LDFLAGS_MODULE
    --------------------------------------------------
    Additional options used for $(LD) when linking modules.

Incremental linking is gone, so rename built-in.o to built-in.a, which
is the usual extension for archive files.

This patch does two things, first is a simple search/replace:

git grep -l 'built-in\.o' | xargs sed -i 's/built-in\.o/built-in\.a/g'

The second is to invert nesting of nested text manipulations to avoid
filtering built-in.a out from libs-y2:

-libs-y2 := $(filter-out %.a, $(patsubst %/, %/built-in.a, $(libs-y)))
+libs-y2 := $(patsubst %/, %/built-in.a, $(filter-out %.a, $(libs-y)))

adds.  Trivially resolved.

In drivers/net/phy/phy.c we had a bug fix in 'net' that moved the
function phy_disable_interrupts() earlier in the file, whilst in
'net-next' the phy_error() call from this function was removed.

In net/ipv4/xfrm4_policy.c, David Ahern's changes to remove the
'rt_table_id' member of rtable collided with a bug fix in 'net' that
added a new struct member "rt_mtu_locked" which needs to be copied
over here.

The mlxsw driver conflict consisted of net-next separating
the span code and definitions into separate files, whilst
a 'net' bug fix made some changes to that moved code.

The mlx5 infiniband conflict resolution was quite non-trivial,
the RDMA tree's merge commit was used as a guide here, and
here are their notes:

====================

    Due to bug fixes found by the syzkaller bot and taken into the for-rc
    branch after development for the 4.17 merge window had already started
    being taken into the for-next branch, there were fairly non-trivial
    merge issues that would need to be resolved between the for-rc branch
    and the for-next branch.  This merge resolves those conflicts and
    provides a unified base upon which ongoing development for 4.17 can
    be based.

    Conflicts:
            drivers/infiniband/hw/mlx5/main.c - Commit 42cea83f95
            (IB/mlx5: Fix cleanup order on unload) added to for-rc and
            commit b5ca15ad7e (IB/mlx5: Add proper representors support)
            add as part of the devel cycle both needed to modify the
            init/de-init functions used by mlx5.  To support the new
            representors, the new functions added by the cleanup patch
            needed to be made non-static, and the init/de-init list
            added by the representors patch needed to be modified to
            match the init/de-init list changes made by the cleanup
            patch.
    Updates:
            drivers/infiniband/hw/mlx5/mlx5_ib.h - Update function
            prototypes added by representors patch to reflect new function
            names as changed by cleanup patch
            drivers/infiniband/hw/mlx5/ib_rep.c - Update init/de-init
            stage list to match new order from cleanup patch

Filip Alac 2ddc8e2d2b HID: usbhid: extend the polling interval configuration to keyboards
For mouse and joystick devices user can change the polling interval
via usbhid.mousepoll and usbhid.jspoll.
Implement the same thing for keyboards, so user can
reduce(or increase) input latency this way.

This has been tested with a Cooler Master Devastator with
kbpoll=32, resulting in delay between events of 32 ms(values were taken
from evtest).

Greg Kroah-Hartman 6d23ee9caa usb: changes for v4.17 merge window
Quite a lot happened in this cycle, with a total of 95 non-merge
 commits. The most interesting parts are listed below:
 
 Synopsys has been adding better support for USB 3.1 to dwc3. The same
 series also sets g_mass_storage's max speed to SSP.
 
 Roger Quadros (TI) added support for dual-role using the OTG block
 available in some dwc3 implementations, this makes sure that AM437x
 can swap roles in runtime.
 
 We have a new SoC supported in dwc3 now - Amlogic Meson GX - thanks to
 the work of Martin Blumenstingl.
 
 We also have a ton of changes in dwc2 (51% of all changes, in
 fact). The most interesting part there is the support for
 Hibernation (a Synopsys PM feature).
 
 Apart from these, we have our regular set of non-critical fixes all
 over the place.

Mimi Zohar 9e67028e76 ima: fail signature verification based on policy
This patch addresses the fuse privileged mounted filesystems in
environments which are unwilling to accept the risk of trusting the
signature verification and want to always fail safe, but are for example
using a pre-built kernel.

This patch defines a new builtin policy named "fail_securely", which can
be specified on the boot command line as an argument to "ima_policy=".

Matthew Garrett d906c10d8a IMA: Support using new creds in appraisal policy
The existing BPRM_CHECK functionality in IMA validates against the
credentials of the existing process, not any new credentials that the
child process may transition to. Add an additional CREDS_CHECK target
and refactor IMA to pass the appropriate creds structure. In
ima_bprm_check(), check with both the existing process credentials and
the credentials that will be committed when the new process is started.
This will not change behaviour unless the system policy is extended to
include CREDS_CHECK targets - BPRM_CHECK will continue to check the same
credentials that it did previously.

After this patch, an IMA policy rule along the lines of:

measure func=CREDS_CHECK subj_type=unconfined_t

will trigger if a process is executed and runs as unconfined_t, ignoring
the context of the parent process. This is in contrast to:

measure func=BPRM_CHECK subj_type=unconfined_t

which will trigger if the process that calls exec() is already executing
in unconfined_t, ignoring the context that the child process executes
into.

Luis R. Rodriguez 5d42c96e1c firmware: add firmware_request_cache() to help with cache on reboot
Some devices have an optimization in place to enable the firmware to
be retaineed during a system reboot, so after reboot the device can skip
requesting and loading the firmware. This can save up to 1s in load
time. The mt7601u 802.11 device happens to be such a device.

When these devices retain the firmware on a reboot and then suspend
they can miss looking for the firmware on resume. To help with this we
need a way to cache the firmware when such an optimization has taken
place.

Maxim MAX663x family are mostly compatible with LM92, but they lack any

to false positives, and current one doesn't detect all chips.  Therefore,
the detect function for max6635 devices is removed in favor of explicit
device instatiation.

Heikki Krogerus fde0aa6c17 usb: common: Small class for USB role switches
USB role switch is a device that can be used to choose the
data role for USB connector. With dual-role capable USB
controllers, the controller itself will be the switch, but
on some platforms the USB host and device controllers are
separate IPs and there is a mux between them and the
connector. On those platforms the mux driver will need to
register the switch.

With USB Type-C connectors, the host-to-device relationship
is negotiated over the Configuration Channel (CC). That
means the USB Type-C drivers need to be in control of the
role switch. The class provides a simple API for the USB
Type-C drivers for the control.

For other types of USB connectors (mainly microAB) the class
provides user space control via sysfs attribute file that
can be used to request role swapping from the switch.

Heikki Krogerus bdecb33af3 usb: typec: API for controlling USB Type-C Multiplexers
USB Type-C connectors consist of various muxes and switches
that route the pins on the connector to the right locations.
The USB Type-C drivers need to be able to control the muxes,
as they are the ones that know things like the cable plug
orientation, and the current mode that was negotiated with
the partner.

This introduces a small API for registering and controlling
cable plug orientation switches, and separate small API for
registering and controlling pin multiplexer/demultiplexer
switches that are needed with Accessory/Alternate Modes.

The motivation for this commit is centralizing the

Richard Leitner 1cbd53c8cd usb: core: introduce per-port over-current counters
For some userspace applications information on the number of
over-current conditions at specific USB hub ports is relevant.

In our case we have a series of USB hardware (using the cp210x driver)
which communicates using a proprietary protocol. These devices sometimes
trigger an over-current situation on some hubs. In case of such an
over-current situation the USB devices offer an interface for reducing
the max used power. As these conditions are quite rare and imply
performance reductions of the device we don't want to reduce the max
power always.

Therefore give user-space applications the possibility to react
adequately by introducing an over_current_counter in the usb port struct
which is exported via sysfs.

Adrian Hunter ad44837882 scsi: ufs: Add support for Auto-Hibernate Idle Timer
UFS host controllers may support an autonomous power management feature
called the Auto-Hibernate Idle Timer. The timer is set to the number of
microseconds of idle time before the UFS host controller will autonomously
put the link into Hibernate state. That will save power at the expense of
increased latency. Any access to the host controller interface registers
will automatically put the link out of Hibernate state. So once configured,
the feature is transparent to the driver.

Expose the Auto-Hibernate Idle Timer value via SysFS to allow users to
choose between power efficiency or lower latency. Set a default value of
150 ms.

Daniel Borkmann says:

====================
pull-request: bpf-next 2018-03-21

The following pull-request contains BPF updates for your *net-next* tree.

The main changes are:

1) Add a BPF hook for sendmsg and sendfile by reusing the ULP infrastructure
   and sockmap. Three helpers are added along with this, bpf_msg_apply_bytes(),
   bpf_msg_cork_bytes(), and bpf_msg_pull_data(). The first is used to tell
   for how many bytes the verdict should be applied to, the second to tell
   that x bytes need to be queued first to retrigger the BPF program for a
   verdict, and the third helper is mainly for the sendfile case to pull in
   data for making it private for reading and/or writing, from John.

2) Improve address to symbol resolution of user stack traces in BPF stackmap.
   Currently, the latter stores the address for each entry in the call trace,
   however to map these addresses to user space files, it is necessary to
   maintain the mapping from these virtual addresses to symbols in the binary
   which is not practical for system-wide profiling. Instead, this option for
   the stackmap rather stores the ELF build id and offset for the call trace
   entries, from Song.

3) Add support that allows BPF programs attached to perf events to read the
   address values recorded with the perf events. They are requested through
   PERF_SAMPLE_ADDR via perf_event_open(). Main motivation behind it is to
   support building memory or lock access profiling and tracing tools with
   the help of BPF, from Teng.

4) Several improvements to the tools/bpf/ Makefiles. The 'make bpf' in the
   tools directory does not provide the standard quiet output except for
   bpftool and it also does not respect specifying a build output directory.
   'make bpf_install' command neither respects specified destination nor
   prefix, all from Jiri. In addition, Jakub fixes several other minor issues
   in the Makefiles on top of that, e.g. fixing dependency paths, phony
   targets and more.

5) Various doc updates e.g. add a comment for BPF fs about reserved names
   to make the dentry lookup from there a bit more obvious, and a comment
   to the bpf_devel_QA file in order to explain the diff between native
   and bpf target clang usage with regards to pointer size, from Quentin
   and Daniel.

Greg Kroah-Hartman c50099f856 Update extcon for 4.17
Detailed description for this pull request:
 1. Add exported extcon function in order to support OF graph binding
 - The extcon consumer driver used the "extcon = <&extcon's phandle"
   property in device-tree in order to bind between extcon provider
   and consumer driver. But, OF graph method is better than 'extcon' property.
   So, extcon subsystem adds the following function to support OF graph binding.
   : extcon_find_edev_by_node(struct device_node *node)
 
 - Create the immutable branch ("ib-extcon-drm-dt-v4.17") for both drm-misc
   and device-tree subsystem. This immutable branch contains the use-case of
   OF graph binding for EXTCON_HDMI connector between MHL device driver
   and extcon provider driver.
 
 2. Fix minor issues of extcon device drivers
 - Remove platform_data and covert to fully use GPIO descriptor for extcon-gpio.c
 - Remove workaround code for id pin direction from extcon-inte-int3496.c
   because GPIO ACPI library does support it with generic way.
 - Set direction and drv flags for V5 boost GPIO because of fixing
   the firmware bug.

Merge tag 'extcon-next-for-4.17' of git://git.kernel.org/pub/scm/linux/kernel/git/chanwoo/extcon into char-misc-next

Chanwoo writes:

Update extcon for 4.17

Detailed description for this pull request:
1. Add exported extcon function in order to support OF graph binding
- The extcon consumer driver used the "extcon = <&extcon's phandle"
  property in device-tree in order to bind between extcon provider
  and consumer driver. But, OF graph method is better than 'extcon' property.
  So, extcon subsystem adds the following function to support OF graph binding.
  : extcon_find_edev_by_node(struct device_node *node)

- Create the immutable branch ("ib-extcon-drm-dt-v4.17") for both drm-misc
  and device-tree subsystem. This immutable branch contains the use-case of
  OF graph binding for EXTCON_HDMI connector between MHL device driver
  and extcon provider driver.

2. Fix minor issues of extcon device drivers
- Remove platform_data and covert to fully use GPIO descriptor for extcon-gpio.c
- Remove workaround code for id pin direction from extcon-inte-int3496.c
  because GPIO ACPI library does support it with generic way.
- Set direction and drv flags for V5 boost GPIO because of fixing
  the firmware bug.

David Lechner 21cdf7269f dt-bindings: clock: New bindings for TI Davinci PSC
This adds a new binding for the Power Sleep Controller (PSC) for the
mach-davinci family of processors.

Note: Although TI Keystone has a very similar PSC, we are not using the
existing bindings. Keystone is using a legacy one-node-per-clock binding
(actually two nodes if you count the separate reset binding for the same
IP block). Also, some davinci LPSCs have quirks that aren't handled by
the keystone bindings, so we would be adding one compatible string per
clock with quirks instead of just a new compatible string for each
controller.

This adds a new binding for the PLL IP blocks in the mach-davinci
family of processors. Currently, only da850 has device tree support
but these bindings can also work for other SoCs in this family just
by adding new compatible strings.

Note: Although these PLL controllers are very similar to the TI Keystone
SoCs, we are not re-using those bindings. The Keystone bindings use a
legacy one-node-per-clock binding. Furthermore, the mach-davinici SoCs
have a slightly different PLL register layout and a number of quirks
that can't be handled by the existing bindings, so the keystone bindings
could not be used as-is anyway.

Rafael J. Wysocki 95c513ec84 ACPI: Add Time and Alarm Device (TAD) driver
Introduce a driver for the ACPI Time and Alarm Device (TAD) based on
Section 9.18 of ACPI 6.2.

This driver only supports the system wakeup capabilities of the TAD
which are mandatory.  Support for the RTC capabilities of the TAD
will be added to it in the future.

This driver is entirely sysfs-based.  It provides attributes (under
the TAD platform device) to allow user space to manage the AC and DC
wakeup timers of the TAD: set and read their values, set and check
their expire timer wake policies, check and clear their status and
check the capabilities of the TAD reported by AML.  The DC timer
attributes are only present if the TAD supports a separate DC alarm
timer.

The wakeup events handling and power management of the TAD is
expected to be taken care of by the ACPI PM domain attached to its
platform device.

Kai-Heng Feng 027bd6cafd usb: core: Add "quirks" parameter for usbcore
Trying quirks in usbcore needs to rebuild the driver or the entire
kernel if it's builtin. It can save a lot of time if usbcore has similar
ability like "usbhid.quirks=" and "usb-storage.quirks=".

Rename the original quirk detection function to "static" as we introduce
this new "dynamic" function.

Now users can use "usbcore.quirks=" as short term workaround before the
next kernel release. Also, the quirk parameter can XOR the builtin
quirks for debugging purpose.

This is inspired by usbhid and usb-storage.

thunderbolt: Changes for v4.17 merge window

New features:

  - Intel Titan Ridge Thunderbolt 3 controller support
  - Preboot ACL supported, allowing more secure way to boot from
    Thunderbolt devices
  - New "USB only" security level

In addition there are a couple of fixes for increasing timeout when
authenticating the ICM firmware and reading root switch config space.
Preventing a crash on certain Lenovo systems where ICM firmware for some
reason is not always properly starting up.

drm/sun4i: Add compatible strings for A80 TCONs
The A80 has 2 or 3 TCONs. The documentation and vendor kernel are very
vague about the third TCON, to the point that it might not exist.

In the documentation, the first TCON is missing channel 1, and the
second is missing channel 0. However the vendor kernel seems to be
able to use them regardless. Here we model them like the old TCONs.

An oddity is that TCON0 requires the reset control for the eDP block
to be deasserted, for any register access to stick.

This patch adds compatible strings for TCON0 and TCON1, with TCON0
requiring an extra "edp" reset control.

We're now ready to map our vectors in weird and wonderful locations.
On enabling ARM64_HARDEN_EL2_VECTORS, a vector slot gets allocated
if this hasn't been already done via ARM64_HARDEN_BRANCH_PREDICTOR
and gets mapped outside of the normal RAM region, next to the
idmap.

That way, being able to obtain VBAR_EL2 doesn't reveal the mapping

access the data pages. Upper bits of the address contain the version
tag. On M7 processors, upper four bits (bits 63-60) contain the version
tag. If a rogue app attempts to access ADI enabled data pages, its
access is blocked and processor generates an exception. Please see
Documentation/sparc/adi.txt for further details.

This patch extends mprotect to enable ADI (TSTATE.mcde), enable/disable
MCD (Memory Corruption Detection) on selected memory ranges, enable
TTE.mcd in PTEs, return ADI parameters to userspace and save/restore ADI
version tags on page swap out/in or migration. ADI is not enabled by
default for any task. A task must explicitly enable ADI on a memory
range and set version tag for ADI to be effective for the task.

Junling Zheng 93cf93f17c f2fs: introduce mount option for fsync mode
Commit "0a007b97aad6"(f2fs: recover directory operations by fsync)
fixed xfstest generic/342 case, but it also increased the written
data and caused the performance degradation. In most cases, there's
no need to do so heavy fsync actually.

So we introduce new mount option "fsync_mode={posix,strict}" to
control the policy of fsync. "fsync_mode=posix" is set by default,
and means that f2fs uses a light fsync, which follows POSIX semantics.
And "fsync_mode=strict" means that it's a heavy fsync, which behaves
in line with xfs, ext4 and btrfs, where generic/342 will pass, but
the performance will regress.

Tony Lindgren 5d1ebbda03 phy: mapphone-mdm6600: Add USB PHY driver for MDM6600 on Droid 4
Let's add support for the GPIO controlled USB PHY on the MDM6600 modem.
It is used on some Motorola Mapphone series of phones and tablets such
as Droid 4.

The MDM6600 is hardwired to the first OHCI port in the Droid 4 case, and
is controlled by several GPIOs. The USB PHY is integrated into the MDM6600
device it seems. We know this as we get L3 errors from omap-usb-host if
trying to use the PHY before MDM6600 is configured.

The GPIOs controlling MDM6600 are used to power device on and off, to
configure the USB start-up mode (normal mode versus USB flashing), and
they also tell the state of the MDM6600 device.

The two start-up mode GPIOs are dual-purposed and used for out of band
(OOB) wake-up for USB and TS 27.010 serial mux. But we need to configure
the USB start-up mode first to get MDM6600 booted in the right mode to
be usable in the first place.

Note that the Motorola Mapphone Linux kernel tree has a "radio-ctrl"
driver for modems. But it really does not control the radio at all, it
just controls the modem power and start-up mode for USB. So I came to
the conclusion that we're better off having this done in the USB PHY
driver. For adding support for USB flashing mode, we can later on add
a kernel module option for flash_mode=1 or something similar.

Also note that currently there is no PM runtime support for the OHCI
on omap variant SoCs. So for low(er) power idle states, currenty both
ohci-platform and phy-mapphone-mdm6600 must be unloaded or unbound.

For reference here is what I measured for total power consumption on
an idle Droid 4 with and without USB related MDM6600 modules:

idle lcd off	phy-mapphone-mdm6600	ohci-platform
153mW		284mW			344mW

So it seems that MDM6600 is currently not yet idling even with it's
radio turned off, but that's something that is beyond the control of
this USB PHY driver. This patch does get us to the point where modem
data and GPS are usable with libqmi and ModemManager for example.
Voice calls need more audio driver work.

Arnd Bergmann bb9d812643 arch: remove tile port
The Tile architecture port was added by Chris Metcalf in 2010, and
maintained until early 2018 when he orphaned it due to his departure
from Mellanox, and nobody else stepped up to maintain it. The product
line is still around in the form of the BlueField SoC, but no longer
uses the Tile architecture.

There are also still products for sale with Tile-GX SoCs, notably the
Mikrotik CCR router family. The products all use old (linux-3.3) kernels
with lots of patches and won't be upgraded by their manufacturers. There
have been efforts to port both OpenWRT and Debian to these, but both
projects have stalled and are very unlikely to be continued in the future.

Given that we are reasonably sure that nobody is still using the port
with an upstream kernel any more, it seems better to remove it now while
the port is in a good shape than to let it bitrot for a few years first.

of some of its oddities like a non-working SMP port, and the amount of
duplication between the chip variants, which cause extra work when

commit 35b3fde620 ("KVM: s390: wire up bpb feature") has no
documentation for KVM_CAP_S390_BPB. While adding this let's also add
other missing capabilities like KVM_CAP_S390_PSW, KVM_CAP_S390_GMAP and
KVM_CAP_S390_COW.

Alexander Usyskin af336cabe0 mei: limit the number of queued writes
Limit the number of queued writes per client.
Writes above this threshold are blocked till place
in the transmit queue is available.
The limit is configurable via sysfs and defaults to 50.
The implementation should provide blocking I/O behavior.
Prior to this change one would end up in the hands of OOM.
