cc69c88fbe platform/x86: dell-smbios: Resolve dependency error on DCDBAS
When the DELL_SMBIOS_SMM backend is enabled, the DELL_SMBIOS symbol
depends on DELL_DCDBAS, and we must avoid the situation where
DELL_SMBIOS=y and DCDBAS=m.

Adding the conditional dependency to DELL_SMBIOS such as:

depends !DELL_SMBIOS_SMM || (DCDBAS || DCDBAS=n)

results in the Kconfig tooling complaining about a circular dependency,
although it appears to work in practice.

Avoid the errors by simplifying the dependency and forcing DELL_SMBIOS
to be <= DCDBAS if DCDBAS is enabled (thanks to Greg KH for the
suggestion).

This reverts commit a376cd9160 because
chromeos_laptop instances should not be marked as "const" (at this

"tries") when we instantiate devices.

c715e43455 platform/x86: Allow for SMBIOS backend defaults
Avoid accidental configurations by setting default y for DELL_SMBIOS
backends. Avoid this impacting the default build size, by making them
dependent on DELL_SMBIOS, so they only appear when DELL_SMBIOS is
manually selected, or by DELL_LAPTOP or DELL_WMI.

While DELL_SMBIOS does have a prompt, it does not have any dependencies.
Keeping DELL_SMBIOS visible, despite being "select"ed by DELL_LAPTOP and
DELL_WMI, is a deliberate choice to provide context for the WMI and SMM
backends, which would otherwise appear to float without context within
the menu.

41e36f2f85 platform/x86: dell-smbios: Link all dell-smbios-* modules together
Some race conditions were raised due to dell-smbios and its backends
not being ready by the time that a consumer would call one of the
exported methods.

To avoid this problem, guarantee that all initialization has been
done by linking them all together and running init for them all.

As part of this change the Kconfig needs to be adjusted so that
CONFIG_DELL_SMBIOS_SMM and CONFIG_DELL_SMBIOS_WMI are boolean
rather than modules.

CONFIG_DELL_SMBIOS is a visually selectable option again and both
CONFIG_DELL_SMBIOS_WMI and CONFIG_DELL_SMBIOS_SMM are optional.

7f83d41044 platform/x86: fujitsu-laptop: Simplify error paths
Replace the last few lines of acpi_fujitsu_bl_add() with a simple return
in order to improve code readability without changing the logic.

As acpi_fujitsu_laptop_add() uses a managed memory allocation for
device-specific data, it is fine to just return immediately upon kfifo
allocation failure.  Do that instead of jumping to the end of the
function to improve code readability.  Running out of memory while
allocating the kfifo does not seem probable enough to warrant logging an
error message, so do not do it.

bf8f65da31 platform/x86: topstar-laptop: add Topstar U931/RVP7 WLAN LED workaround
Topstar U931 laptops provide a LED synced with the WLAN adapter
hard-blocking state. Unfortunately, some models seem to be defective,
making impossible to hard-block the adapter with the WLAN switch and
thus the LED is useless.

An ACPI method is available to programmatically control this switch and
it indirectly allows to control the LED.

This commit registers the LED within the corresponding subsystem, making
possible for instance to use an rfkill-based trigger to synchronize the
LED with the device state.

This workaround is enabled automatically for Topstar U931/RVP7 laptops
based on a DMI check.

TURBO 3.0 didn't use this method to show core priority. So users are not
able to utilize this feature in HWP mode.

So remove the loading restriction of this driver for HWP enabled systems.
Even if there are some systems, which are providing the core priority via
ACPI CPPC, this shouldn't cause any conflict as the source of priority
definition is same.

a9a08845e9 vfs: do bulk POLL* -> EPOLL* replacement
This is the mindless scripted replacement of kernel use of POLL*
variables as described by Al, done by this script:

    for V in IN OUT PRI ERR RDNORM RDBAND WRNORM WRBAND HUP RDHUP NVAL MSG; do
        L=`git grep -l -w POLL$V | grep -v '^t' | grep -v /um/ | grep -v '^sa' | grep -v '/poll.h$'|grep -v '^D'`
        for f in $L; do sed -i "-es/^\([^\"]*\)\(\<POLL$V\>\)/\\1E\\2/" $f; done
    done

with de-mangling cleanups yet to come.

NOTE! On almost all architectures, the EPOLL* constants have the same
values as the POLL* constants do.  But they keyword here is "almost".
For various bad reasons they aren't the same, and epoll() doesn't
actually work quite correctly in some cases due to this on Sparc et al.

The next patch from Al will sort out the final differences, and we
should be all done.

Indeed, if mlxreg_core_item.count is zero, ret is used uninitialized.

While this is unlikely to happen (it is set to ARRAY_SIZE(...) in x86

preinitializing ret to zero.

Add definitions for hotplug device masks and events offsets, in order to
specify explicitly all hardware registers allowed for IO operations for
all the drivers sharing register map with mlx-platform.

Extend register map configuration with the sets of writable, readable and

unexpected access to hardware registers by the drivers, sharing register
map with mlx-platform.

Extend register map configuration with cache type field in order to have
ability to cache hardware register value, where possible. Use simple flat
array type for register lookups, which is most suitable in case when the
number of the registers is not too large.

Add at the end of probing routine calls to regcache_mark_dirty and
regcache_sync in order to sync register cache with hardware values. The
first routine indicate that hardware registers value required sync, the
second performs sync.

d6fa7588fd Revert "apple-gmux: lock iGP IO to protect from vgaarb changes"
Commit 4eebd5a4e7 ("apple-gmux: lock iGP IO to protect from vgaarb
changes") amended this driver's ->probe hook to lock decoding of normal
(non-legacy) I/O space accesses to the integrated GPU on dual-GPU
MacBook Pros.  The lock stays in place until the driver is unbound.

The change was made to work around an issue with the out-of-tree nvidia
graphics driver (available at http://www.nvidia.com/object/unix.html).
It contains the following sequence in nvidia/nv.c:

	#if defined(CONFIG_VGA_ARB) && !defined(NVCPU_PPC64LE)
	#if defined(VGA_DEFAULT_DEVICE)
	    vga_tryget(VGA_DEFAULT_DEVICE, VGA_RSRC_LEGACY_MASK);
	#endif
	    vga_set_legacy_decoding(dev, VGA_RSRC_NONE);
	#endif

This code was reported to cause deadlocks with VFIO already in 2013:
https://devtalk.nvidia.com/default/topic/545560

I've reported the issue to Nvidia developers once more in 2017:
https://www.spinics.net/lists/dri-devel/msg138754.html

On the MacBookPro10,1, this code apparently breaks backlight control
(which is handled by apple-gmux via an I/O region starting at 0x700),
as reported by Petri Hodju:
https://bugzilla.kernel.org/show_bug.cgi?id=86121

I tried to replicate Petri's observations on my MacBook9,1, which uses
the same Intel Ivy Bridge + Nvidia GeForce GT 650M architecture, to no
avail.  On my machine apple-gmux' I/O region remains accessible even
with the nvidia driver loaded and commit 4eebd5a4e7 reverted.
Petri reported that apple-gmux becomes accessible again after a
suspend/resume cycle because the BIOS changed the VGA routing on the
root port to the Nvidia GPU.  Perhaps this is a BIOS issue after all
that can be fixed with an update?

In any case, the change made by commit 4eebd5a4e7 has turned out to
cause two new issues:

* Wilfried Klaebe reports a deadlock when launching Xorg because it
  opens /dev/vga_arbiter and calls vga_get(), but apple-gmux is holding
  a lock on I/O space indefinitely.  It looks like apple-gmux' current
  behavior is an abuse of the vgaarb API as locks are not meant to be
  held for longer periods:
  https://bugzilla.kernel.org/show_bug.cgi?id=88861#c11
  https://bugzilla.kernel.org/attachment.cgi?id=217541

* On dual GPU MacBook Pros introduced since 2013, the integrated GPU is
  powergated on boot und thus becomes invisible to Linux unless a custom
  EFI protocol is used to leave it powered on.  (A patch exists but is
  not in mainline yet due to several negative side effects.)  On these
  machines, locking I/O to the integrated GPU (as done by 4eebd5a4e7)
  fails and backlight control is therefore broken:
  https://bugzilla.kernel.org/show_bug.cgi?id=105051

So let's revert commit 4eebd5a4e7 please.  Users experiencing the
issue with the proprietary nvidia driver can comment out the above-
quoted problematic code as a workaround (or try updating the BIOS).

168fe32a07 Merge branch 'misc.poll' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs
Pull poll annotations from Al Viro:
 "This introduces a __bitwise type for POLL### bitmap, and propagates
  the annotations through the tree. Most of that stuff is as simple as
  'make ->poll() instances return __poll_t and do the same to local
  variables used to hold the future return value'.

  Some of the obvious brainos found in process are fixed (e.g. POLLIN
  misspelled as POLL_IN). At that point the amount of sparse warnings is
  low and most of them are for genuine bugs - e.g. ->poll() instance
  deciding to return -EINVAL instead of a bitmap. I hadn't touched those
  in this series - it's large enough as it is.

  Another problem it has caught was eventpoll() ABI mess; select.c and
  eventpoll.c assumed that corresponding POLL### and EPOLL### were
  equal. That's true for some, but not all of them - EPOLL### are
  arch-independent, but POLL### are not.

  The last commit in this series separates userland POLL### values from
  the (now arch-independent) kernel-side ones, converting between them
  in the few places where they are copied to/from userland. AFAICS, this
  is the least disruptive fix preserving poll(2) ABI and making epoll()
  work on all architectures.

  As it is, it's simply broken on sparc - try to give it EPOLLWRNORM and
  it will trigger only on what would've triggered EPOLLWRBAND on other
  architectures. EPOLLWRBAND and EPOLLRDHUP, OTOH, are never triggered
  at all on sparc. With this patch they should work consistently on all
  architectures"

21ae435709 platform/x86: intel_pmc_core: Substitute PCI with CPUID enumeration
The Only use of PCI device enumeration here is to get the PMC base address
which is a fixed value i.e. 0xFE000000. On some platforms this can be read
through a non standard PCI BAR. But after Kabylake, PMC is not exposed as a
PCI device anymore. There are other non standard methods like ACPI LPIT
which can also be used for obtaining this value.

For simplicity, this value can be hardcoded as it won't change.

Since we don't have a PMC PCI device on any platform after Kabylake, this
creates a foundation for future SoC support.

587d8628fb platform/x86: thinkpad_acpi: suppress warning about palm detection
This patch prevents the thinkpad_acpi driver from warning about 2 event
codes returned for keyboard palm-detection. No behavioral changes,
other than suppressing the warning in the kernel log. The events are
still forwarded via acpi-netlink channels.

We could, optionally, decide to forward the event through a
input-switch on the tpacpi input device. However, so far no suitable
input-code exists, and no similar drivers report such events. Hence,
leave it an acpi event for now.

Note that the event-codes are named based on empirical studies. On the
ThinkPad X1 5th Gen the sensor can be found underneath the arrow key.

4d6bde512a platform/x86: dell-laptop: Filter out spurious keyboard backlight change events
On some Dell XPS models WMI events of type 0x0000 reporting a keycode of
0xe00c get reported when the brightness of the LCD panel changes.

This leads to us reporting false-positive kbd_led change events to
userspace which in turn leads to the kbd backlight OSD showing when it
should not.

We already read the current keyboard backlight brightness value when
reporting events because the led_classdev_notify_brightness_hw_changed
API requires this. Compare this value to the last known value and filter
out duplicate events, fixing this.

Note the fixed issue is esp. a problem on XPS models with an ambient light
sensor and automatic brightness adjustments turned on, this causes the kbd
backlight OSD to show all the time there.

Drivers should not 'select' a subsystem. Instead they should depend
on it. If the subsystem is disabled, the user probably did that for
a purpose and one driver shouldn't be changing that.

This also makes all platform/x86/ drivers consistent w.r.t depending on
INPUT instead of selecting it.

98b8e4e5c1 platform/x86: wmi: Call acpi_wmi_init() later
Calling acpi_wmi_init() at the subsys_initcall() level causes ordering
issues to appear on some systems and they are difficult to reproduce,
because there is no guaranteed ordering between subsys_initcall()
calls, so they may occur in different orders on different systems.

In particular, commit 86d9f48534 (mm/slab: fix kmemcg cache
creation delayed issue) exposed one of these issues where genl_init()
and acpi_wmi_init() are both called at the same initcall level, but
the former must run before the latter so as to avoid a NULL pointer
dereference.

For this reason, move the acpi_wmi_init() invocation to the
initcall_sync level which should still be early enough for things
to work correctly in the WMI land.

drivers/platform/chrome/cros_ec_sysfs.c: In function 'show_ec_version':
drivers/platform/chrome/cros_ec_sysfs.c:190:12: error: array subscript 4294967295 is above array bounds of 'uint8_t[]' [-Werror=array-bounds]

This changes the code back to what it did before changing to a
zero-length array structure.

5e0115581b cros_ec: Move cros_ec_dev module to drivers/mfd
The cros_ec_dev module is responsible for registering the MFD devices
attached to the ChromeOS EC. This patch moves this module to drivers/mfd
so calls to mfd_add_devices() are not done from outside the MFD subtree
anymore.

ea01a31b90 cros_ec: Split cros_ec_devs module
This patch splits the cros_ec_devs module in two parts with a
cros_ec_dev module responsible for handling MFD devices registration and
a cros_ec_ctl module responsible for handling the various user-space
interfaces.

For consistency purpose, the driver name for the cros_ec_dev module is
now cros-ec-dev instead of cros-ec-ctl.

In the next commit, the new cros_ec_dev module will be moved to the MFD
subtree so mfd_add_devices() calls are not done from outside MFD.

1c3fdf125e platform/x86: intel-vbtn: Simplify autorelease logic
The new notify_handler logic determining if autorelease should be used or
not is a bit awkward, and can result in more than one call to
sparse_keymap_report_event for the same event (scancode). The nesting
and long lines also made it difficult to read.

Simplify the logic by eliminating a level of nesting with a goto and
always calculate autorelease and val so we can make a single call to
sparse_keymap_report_event.

Suspend with shallow wakes is not a useful parameter since the phenomena
does not exist on deployed devices and is only a parameter of use during
device power-on phase. The field always reads zero. Additionally there
are other easier methods to detect it, e.g., if the S0ix counter
increments by more than one during suspend. Hence the field is superfluous
and can be removed.

This patch also slightly renames the S0ix total field for better
viewability.

Suspend stats are not reported consistently due to a limitation in the PMC
firmware. This limitation causes a delay in updating the s0ix counters and
residencies in the telemetry log upon s0ix exit. As a consequence, reading
these counters from the suspend-exit notifier may result in zero read.

This patch fixes this issue by cross-verifying the s0ix residencies from
the GCR TELEM registers in case the counters are not incremented in the
telemetry log after suspend.
