Use devm_input_allocate_device to simplify the error handling code.
This conversion also makes input_register_device() to be called after
acpi_remove_notify_handler. This avoid a small window that it's possible
to call notify_handler after unregister input device.

SPT LTR_IGN register provides a means to make the PMC ignore the LTR values
reported by the individual PCH devices.
echo <IP Offset> > /sys/kernel/debug/pmc_core/ltr_ignore.
When a particular IP Offset bit is set the PMC will ignore the LTR value
reported by the corresponding IP when the PMC performs the latency
coalescing.

ModPhy Common lanes can provide the clock gating status for the important
system PLLs such as Gen2 USB3PCIE2 PLL, DMIPCIE3 PLL, SATA PLL and MIPI
PLL.
On SPT, in addition to the crystal oscillator clock, the 100Mhz Gen2
USB3PCI2 PLL clock is used as the PLL reference clock and Gen2 PLL idling
is a necessary condition for the platform to go into low power states like
PC10 and S0ix.

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.

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.
Sample output (stripped and not in order):
cat /sys/kernel/debug/pmc_core/pch_ip_power_gating_status

On Sunrise Point PCH, the Power Management Controller provides 4K bytes of
memory space for various power management and debug registers. This fix is
needed to access power management & debug registers that are mapped at a
higher offset.
Also, this provides a fix for correctly masking the PWRMBASE as the initial
bits (0-11) are reserved.

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.

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.

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 38e088546522
("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 ]
* gup_flag-cleanups:
mm: replace access_process_vm() write parameter with gup_flags
mm: replace access_remote_vm() write parameter with gup_flags
mm: replace __access_remote_vm() write parameter with gup_flags
mm: replace get_user_pages_remote() write/force parameters with gup_flags
mm: replace get_user_pages() write/force parameters with gup_flags
mm: replace get_vaddr_frames() write/force parameters with gup_flags
mm: replace get_user_pages_locked() write/force parameters with gup_flags

mm: remove write/force parameters from __get_user_pages_unlocked()
mm: remove write/force parameters from __get_user_pages_locked()
mm: remove gup_flags FOLL_WRITE games from __get_user_pages()
|
|
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.

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().

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.

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
- Trip point changed
- thermal device up and down
- thermal device power capability changed

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.

Two of the internal functions are printing an info message, one
whenever the HDD protection level changes, and another when the
driver receives an ACPI event.
This patch changes those two prints to debug, as that information
is more pertaining to debuging purposes.

Currently the code checking for the ACPI status is mixed along with
the actual HDD protection status check.
This patch splits those two checks as they are not related, printing
an error string in case the ACPI call failed, and then check for
actual HDD protection status.

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)
As a result of this patch asus-laptop.ko size is reduced by almost 1%:

Currently the success/error checking logic is intermixed, making the
code a bit cumbersome to understand.
This patch changes the affected functions to first check for errors
and take appropriate actions, then check for the supported features.
This patch also separates the error check from the acpi_status and
the tci_raw function call error check, as those two are completely
unrelated and were nested in if/else statements.

Newer revisions of the ChromeOS EC add more events besides the keyboard
ones. So handle interrupts in the MFD driver and let consumers register
for notifications for the events they might care.
To keep backward compatibility, if the EC doesn't support MKBP event, we
fall back to the old MKBP key matrix host command.
