97a32539b9 proc: convert everything to "struct proc_ops"
The most notable change is DEFINE_SHOW_ATTRIBUTE macro split in
seq_file.h.

Conversion rule is:

	llseek		=> proc_lseek
	unlocked_ioctl	=> proc_ioctl

	xxx		=> proc_xxx

	delete ".owner = THIS_MODULE" line

034dbec179 platform/chrome: cros_ec: Match implementation with headers
The 'cros_ec' core driver is the common interface for the cros_ec
transport drivers to do the shared operations to register, unregister,
suspend, resume and handle_event. The interface is provided by including
the header 'include/linux/platform_data/cros_ec_proto.h', however, instead
of have the implementation of these functions in cros_ec_proto.c, it is in
'cros_ec.c', which is a different kernel module. Apart from being a bad
practice, this can induce confusions allowing the users of the cros_ec
protocol to call these functions.

The register, unregister, suspend, resume and handle_event functions
*should* only be called by the different transport drivers (i2c, spi, lpc,
etc.), so make this a bit less confusing by moving these functions from
the public in-kernel space to a private include in platform/chrome, and
then, the interface for cros_ec module and for the cros_ec_proto module is
clean.

dccad6f78c platform/x86: intel_menlow: switch to use <linux/units.h> helpers
This switches the intel_menlow driver to use deci_kelvin_to_celsius()
and celsius_to_deci_kelvin() in <linux/units.h> instead of helpers in
<linux/thermal.h>.

This is preparation for centralizing the kelvin to/from Celsius
conversion helpers in <linux/units.h>.

This also removes a trailing space, while we're at it.

f07b9fdf00 platform/x86: asus-wmi: switch to use <linux/units.h> helpers
The asus-wmi driver doesn't implement the thermal device functionality
directly, so including <linux/thermal.h> just for
DECI_KELVIN_TO_CELSIUS() is a bit odd.

This switches the asus-wmi driver to use deci_kelvin_to_millicelsius()
in <linux/units.h>.

The format string is changed from %d to %ld due to function returned
type.

f1f6a7dd9b mm, tree-wide: rename put_user_page*() to unpin_user_page*()
In order to provide a clearer, more symmetric API for pinning and
unpinning DMA pages.  This way, pin_user_pages*() calls match up with
unpin_user_pages*() calls, and the API is a lot closer to being
self-explanatory.

57459435cf goldish_pipe: convert to pin_user_pages() and put_user_page()
1. Call the new global pin_user_pages_fast(), from
   pin_goldfish_pages().

2. As required by pin_user_pages(), release these pages via
   put_user_page().  In this case, do so via put_user_pages_dirty_lock().

That has the side effect of calling set_page_dirty_lock(), instead of
set_page_dirty().  This is probably more accurate.

As Christoph Hellwig put it, "set_page_dirty() is only safe if we are
dealing with a file backed page where we have reference on the inode it
hangs off." [1]

Another side effect is that the release code is simplified because the
page[] loop is now in gup.c instead of here, so just delete the local
release_user_pages() entirely, and call put_user_pages_dirty_lock()
directly, instead.

There is no reason why the driver would need to block other threads from

with a bit more relaxed polling loop.

Also add constant for the timeout and use the same value for both

1b5937cb63 platform/x86: mlx-platform: Add more definitions for system attributes
Add new attributes for "next-generation" type systems:
- Reset cause indication, when system reset has been caused by the
  platform reset request through CPLD, by AC power failure,
  by software power off request through CPLD. by signal asserted by SOC
  through ACPI register. It introduces more reset causes, which can
  be monitored after the reboots.
- Setting and removing system VPD (EEPROM) hardware write protection.
  It allows to access VPD during production cycle and prevents VPD
  corruption on system in field.
- Voltage regulator devices configuration update status and version. It
  allows to monitor configuration update status and current active
  version for such sort of devices.
- PCIe ASIC reset disable - when set ASIC will go down upon PCIe
  root complex reset, otherwise ASIC will stay up during PCIe root
  complex reset.
- System configuration Ids to provide system static topology
  identification, like system's static I2C topology, number and type of
  FPGA devices within the system and so on.

Add the existing attribute for "iio" bank selection for system type
"msn21xx".

All the above attributes are exposed through "sysfs" by "mlxreg-io"
driver.

49a474c7ba platform/x86: Add support for Uncore frequency control
Some server users set limits on the uncore frequency using MSR 620H, while
running latency sensitive workloads. Here uncore frequency controls
RING/LLC(last-level cache) clocks.

But MSR control is not always possible from the user space, so this driver
provides a sysfs interface to set max and min frequency limits. This MSR
620H is a die scoped in multi-die system or package scoped in non multi-die
systems.

When this driver is loaded, a new directory is created under
 /sys/devices/system/cpu.

For example on a two package Skylake server:
$cd /sys/devices/system/cpu/intel_uncore_frequency

$ls
package_00_die_00 package_01_die_00

$ls package_00_die_00
max_freq_khz  min_freq_khz  initial_max_freq_khz
initial_min_freq_khz

$grep . *
    max_freq_khz:2400000
    min_freq_khz:1200000
    initial_max_freq_khz:2400000
    initial_min_freq_khz:1200000

Here, initial_max_freq_khz and initial_min_freq_khz are read only
attributes to show power up or initial values of max and min frequencies
respectively. Other attributes are read-write, so that users can modify.

6ae01050e4 platform/x86: GPD pocket fan: Use default values when wrong modparams are given
Use our default values when wrong module-parameters are given, instead of
refusing to load. Refusing to load leaves the fan at the BIOS default
setting, which is "Off". The CPU's thermal throttling should protect the
system from damage, but not-loading is really not the best fallback in this
case.

This commit fixes this by re-setting module-parameter values to their
defaults if they are out of range, instead of failing the probe with
-EINVAL.

638bc4ca3d platform/mellanox: fix potential deadlock in the tmfifo driver
This commit fixes the potential deadlock caused by the console Rx
and Tx processing at the same time. Rx and Tx both take the console
and tmfifo spinlock but in different order which causes potential
deadlock. The fix is to use different tmfifo spinlock for Rx and
Tx since they protect different resources and it's safe to split
the lock.

Below is the reported call trace when copying/pasting large string
in the console.

Rx:
    _raw_spin_lock_irqsave (hvc lock)
    __hvc_poll
    hvc_poll
    in_intr
    vring_interrupt
    mlxbf_tmfifo_rxtx_one_desc (tmfifo lock)

11f1eabee0 cros_ec: treewide: Remove 'include/linux/mfd/cros_ec.h'
This header file now only includes the cros_ec_dev struct, however, is the
'include/linux/platform_data/cros_ec_proto.h' who contains the definition of
all the Chrome OS EC related structs. There is no reason to have a
separate include for this struct so move to the place where other
structs are defined. That way, we can remove the include itself, but also
simplify the common pattern

    #include <linux/mfd/cros_ec.h>
    #include <linux/platform_data/cros_ec_proto.h>

for a single include

    #include <linux/platform_data/cros_ec_proto.h>

The changes to remove the cros_ec.h include were generated with the
following shell script:

    git grep -l "<linux/mfd/cros_ec.h>" | xargs sed -i '/<linux\/mfd\/cros_ec.h>/d'

- Fill the struct cacheinfo shared_cpu_map field with sensible values,
   notably avoiding issues with perf which was unhappy in the absence of
   these values.
 
 - A boot fix for Loongson 2E & 2F machines which was fallout from some
   refactoring performed this cycle.
 
 - A Kconfig dependency fix for the Loongson CPU HWMon driver.
 
 - A couple of VDSO fixes, ensuring gettimeofday() behaves appropriately
   for kernel configurations that don't include support for a clocksource
   the VDSO can use & fixing the calling convention for the n32 & n64
   VDSOs which would previously clobber the $gp/$28 register.
 
 - A build fix for vmlinuz compressed images which were inappropriately
   building with -fsanitize-coverage despite not being part of the kernel
   proper, then failing to link due to the missing
   __sanitizer_cov_trace_pc() function.
 
 - A couple of eBPF JIT fixes, including disabling it for MIPS32 due to a
   large number of issues with the code generated there & reflecting ISA
   dependencies in Kconfig to enforce that systems which don't support
   the JIT must include the interpreter.

e398547818 platform/x86: intel_pmc_core: Create platform dependent bitmap structs
The current implementation of intel_pmc_core driver allows to reuse, but does
not reflect the exact number and names of IPs for a newer platform which
does not necessarily support all the IPs in the entries. The names and
number of these IPs might differ from its previous platforms. The number
of PCH IPs per platform is calculated based on PPFEAR_NUM_ENTRIES
defined, where each entry represents a bucket (8 bits). The platform can
support 'n' entries, but not necessarily all 'n * 8' IPs.

Create platform dependent bitmap structures to specify the exact number,
names of IPs while reusing the existing IPs.

The changes in this patch are preparatory to accommodate future SoCs
that might reuse the CNL/ICL PCH IPs, and to reflect the exact number of
IPs with its names.

b1cb33dae4 platform/x86: intel_pmc_core: Clean up: Remove comma after the termination line
It is common practice to place a comma after the last entry in an
initialized array to avoid the need to add one in future patches that
extend the array. But when the last element is a termination marker, the
comma could be harmful. Any new entries must be added before the
terminator (and the comma would prevent the compiler from issuing a
warning about an entry after the terminator).

- Various kerneldoc script enhancements.
 
  - More RST conversions; those are slowing down as we run out of things to
    convert, but we're a ways from done still.
 
  - Dan's "maintainer profile entry" work landed at last.  Now we just need
    to get maintainers to fill in the profiles...
 
  - A reworking of the parallel build setup to work better with a variety of
    systems (and to not take over huge systems entirely in particular).
 
  - The MAINTAINERS file is now converted to RST during the build.
    Hopefully nobody ever tries to print this thing, or they will need to
    load a lot of paper.
 
  - A script and documentation making it easy for maintainers to add Link:
    tags at commit time.
 
 Also included is the removal of a bunch of spurious CR characters.

Merge tag 'docs-5.5a' of git://git.lwn.net/linux

Pull Documentation updates from Jonathan Corbet:
 "Here are the main documentation changes for 5.5:

   - Various kerneldoc script enhancements.

   - More RST conversions; those are slowing down as we run out of
     things to convert, but we're a ways from done still.

   - Dan's "maintainer profile entry" work landed at last. Now we just
     need to get maintainers to fill in the profiles...

   - A reworking of the parallel build setup to work better with a
     variety of systems (and to not take over huge systems entirely in
     particular).

   - The MAINTAINERS file is now converted to RST during the build.
     Hopefully nobody ever tries to print this thing, or they will need
     to load a lot of paper.

   - A script and documentation making it easy for maintainers to add
     Link: tags at commit time.

  Also included is the removal of a bunch of spurious CR characters"

0da522107e compat_ioctl: remove most of fs/compat_ioctl.c
As part of the cleanup of some remaining y2038 issues, I came to
 fs/compat_ioctl.c, which still has a couple of commands that need support
 for time64_t.
 
 In completely unrelated work, I spent time on cleaning up parts of this
 file in the past, moving things out into drivers instead.
 
 After Al Viro reviewed an earlier version of this series and did a lot
 more of that cleanup, I decided to try to completely eliminate the rest
 of it and move it all into drivers.
 
 This series incorporates some of Al's work and many patches of my own,
 but in the end stops short of actually removing the last part, which is
 the scsi ioctl handlers. I have patches for those as well, but they need
 more testing or possibly a rewrite.

3f1b210a7f sound updates for 5.5-rc1
There have been some significant changes in the core side, both for
 ALSA and ASoC, while lots of development have been seen in SOF, as
 well as many small fixes/improvements for ASoC codecs and platforms.
 Below is a highlight in this cycle:
 
 Core:
 - The unification of PCM vmalloc buffer allocation helpers into the
   standard API
 - Clean up of the default PCM mmap handling for vmalloc & SG-buffer
 - Fix potential races at ALSA timer open
 - A few new PCM API extensions; just preliminary core changes, the
   actual changes in drivers will be merged in 5.6
 - Continued ASoC componentization works; now almost everything is a
   common ASoC component object.  A lot of refactoring and
   simplification have been done along with it.
 
 ASoC:
 - Many fixes to the Sound Open Firmware (SOF) code
 - Wake on voice support for Chromebooks
 - SPI support and trigger word detection for RT5677
 - New drivers for Analog Devices ADAU7118, Intel Cannonlake systems
   with RT1011 and RT5682, Texas Instruments TAS2562 and TAS2770
 
 HD-audio:
 - Improved Intel DSP configuration / probe code for SOF
 - Plumbing the legacy HD-audio driver with Intel SOF HDMI
 - DP-MST support for Nvidia HDMI codecs
 - Realtek quirks cleanups and new additions as usual
 
 Others:
 - Lots of refactoring and cleanups for FireWire; period-size sharing,
   h/w IRQ interval configuration, clock recovery improvements, etc
 - USB-audio: Scarlett mixer quirks
 - Cleanups of PCM calls in various drivers (including media and USB)
   to adapt the core API changes

f3e4f3fc8e platform/x86: hp-wmi: Fix ACPI errors caused by passing 0 as input size
The AML code implementing the WMI methods creates a variable length
field to hold the input data we pass like this:

        CreateDWordField (Arg1, 0x0C, DSZI)
        Local5 = DSZI /* \HWMC.DSZI */
        CreateField (Arg1, 0x80, (Local5 * 0x08), DAIN)

If we pass 0 as bios_args.datasize argument then (Local5 * 0x08)
is 0 which results in these errors:

[   71.973305] ACPI BIOS Error (bug): Attempt to CreateField of length zero (20190816/dsopcode-133)
[   71.973332] ACPI Error: Aborting method \HWMC due to previous error (AE_AML_OPERAND_VALUE) (20190816/psparse-529)
[   71.973413] ACPI Error: Aborting method \_SB.WMID.WMAA due to previous error (AE_AML_OPERAND_VALUE) (20190816/psparse-529)

And in our HPWMI_WIRELESS2_QUERY calls always failing. for read commands
like HPWMI_WIRELESS2_QUERY the DSZI value is not used / checked, except for
read commands where extra input is needed to specify exactly what to read.

So for HPWMI_WIRELESS2_QUERY we can safely pass the size of the expected
output as insize to hp_wmi_perform_query(), as we are already doing for all
other HPWMI_READ commands we send. Doing so fixes these errors.

16245db148 platform/x86: hp-wmi: Fix ACPI errors caused by too small buffer
The HP WMI calls may take up to 128 bytes of data as input, and
the AML methods implementing the WMI calls, declare a couple of fields for
accessing input in different sizes, specifycally the HWMC method contains:

        CreateField (Arg1, 0x80, 0x0400, D128)

Even though we do not use any of the WMI command-types which need a buffer
of this size, the APCI interpreter still tries to create it as it is
declared in generoc code at the top of the HWMC method which runs before
the code looks at which command-type is requested.

This results in many of these errors on many different HP laptop models:

[   14.459261] ACPI Error: Field [D128] at 1152 exceeds Buffer [NULL] size 160 (bits) (20170303/dsopcode-236)
[   14.459268] ACPI Error: Method parse/execution failed [\HWMC] (Node ffff8edcc61507f8), AE_AML_BUFFER_LIMIT (20170303/psparse-543)
[   14.459279] ACPI Error: Method parse/execution failed [\_SB.WMID.WMAA] (Node ffff8edcc61523c0), AE_AML_BUFFER_LIMIT (20170303/psparse-543)

This commit increases the size of the data element of the bios_args struct
to 128 bytes fixing these errors.

3300fdd630 platform/chrome: cros_ec: handle MKBP more events flag
The ChromeOS EC has support for signaling to the host that a single IRQ
can serve multiple MKBP (Matrix KeyBoard Protocol) events.

Doing this serves an optimization purpose, as it minimizes the number of
round-trips into the interrupt handling machinery, and it proves
beneficial to sensor timestamping as it keeps the desired synchronization
of event times between the two processors.

This patch adds kernel support for this EC feature, allowing the ec_irq
to loop until all events have been served.

4a8d82cdec platform/x86: intel_int0002_vgpio: Pass irqchip when adding gpiochip
We need to convert all old gpio irqchips to pass the irqchip
setup along when adding the gpio_chip. For more info see
drivers/gpio/TODO.

For chained irqchips this is a pretty straight-forward
conversion. This driver requests the IRQ directly in the driver
so it needs to pass a NULL parent handler. We may revisit this
code later and pull reqular shared IRQ handler into
gpiolib, so leave a FIXME.

1832f2d8ff compat_ioctl: move more drivers to compat_ptr_ioctl
The .ioctl and .compat_ioctl file operations have the same prototype so
they can both point to the same function, which works great almost all
the time when all the commands are compatible.

One exception is the s390 architecture, where a compat pointer is only
31 bit wide, and converting it into a 64-bit pointer requires calling
compat_ptr(). Most drivers here will never run in s390, but since we now
have a generic helper for it, it's easy enough to use it consistently.

I double-checked all these drivers to ensure that all ioctl arguments
are used as pointers or are ignored, but are not interpreted as integer
values.
