The powerpc64 kernel exception handlers have preserved thread priorities
for a long time now, so there is no need to continually set it.
Just set it once on entry and once exit.

The core of snooze_loop() continually bounces between low and very
low thread priority. Changing thread priorities is an expensive
operation that can negatively impact other threads on a core.
All CPUs that can run PowerNV support very low priority, so we can
avoid the change completely.

acpi_bus_attach() does not check the visited flag for devices that
have been enumerated already and some of them may be enumerated
for multiple times as a result, because some callers of
acpi_bus_scan() don't check the visited flag either.
For this reason, modify acpi_bus_attach() to check the visited flag
and avoid enumerating devices that have already been enumerated.

The current code in acpi_bus_attach() is inconsistent with respect
to device objects with ACPI drivers bound to them, as it allows
ACPI drivers to bind to device objects with existing "physical"
device companions, but it doesn't allow "physical" device objects
to be created for ACPI device objects with ACPI drivers bound to
them. Thus, in some cases, the outcome depends on the ordering
of events which is confusing at best.
For this reason, modify acpi_bus_attach() to call
acpi_default_enumeration() for device objects with the
pnp.type.platform_id flag set regardless of whether or not
any ACPI drivers are bound to them.

On some devices with an axp288 pmic setting vbus path based on the
id-pin is handled by an ACPI _AIE interrupt on the gpio and the
INT3496 device is disabled.
Instead of returning -EPROBE_DEFER on these devices waiting for the
never to show up INT3496 device, check for its presence and only
request and monitor the matching extcon if the device is there,
otherwise let the firmware handle the vbus path control.

On some systems we have a native PMIC driver which provides Mains
monitoring, while the ACPI ac driver is broken on these systems
due to bad DSTDs or because we do not support the proprietary and
undocumented ACPI opregions these ACPI battery devices rely on
(e.g. BMOP opregion).
This leads for example to a ADP1 power_supply which reports
itself as always online even if no mains are connected.
This commit adds a blacklist with PMIC ACPI HIDs for which we've a
native charger or extcon driver and makes the ACPI ac driver not
register itself when a PMIC on this list is present.

due to bad DSDTs or because we do not support the proprietary and
undocumented ACPI opregions these ACPI battery devices rely on
(e.g. BMOP opregion).
This leads to there being 2 battery power_supply-s registed like this:
~$ acpi
Battery 0: Charging, 84%, 00:49:39 until charged
Battery 1: Unknown, 0%, rate information unavailable
Even if the ACPI battery where to function fine (which on systems
where we have a native PMIC driver it often doesn't) we still do not
want to export the same battery to userspace twice.
This commit adds a blacklist with PMIC ACPI HIDs for which we've a

acpi_dev_found just iterates over all ACPI-ids and sees if one matches.
This means that it will return true for devices which are in the DSDT
but disabled (their _STA method returns 0).
For some drivers it is useful to be able to check if a certain HID
is not only present in the namespace, but also actually present as in
acpi_device_is_present() will return true for the device. For example
because if a certain device is present then the driver will want to use
an extcon or IIO ADC channel provided by that device.
This commit adds a new acpi_dev_present helper which drivers can use
to this end.
Like acpi_dev_found, acpi_dev_present take a HID as argument, but
it also has 2 extra optional arguments to only check for an ACPI
device with a specific UID and/or HRV value. This makes it more
generic and allows it to replace custom code doing similar checks
in several places.
Arguably acpi_dev_present is what acpi_dev_found should have been, but
there are too many users to just change acpi_dev_found without the risk
of breaking something.

gcc -O2 cannot always prove that the loop in acpi_power_get_inferred_state()
is enterered at least once, so it assumes that cur_state might not get
initialized:
drivers/acpi/power.c: In function 'acpi_power_get_inferred_state':
drivers/acpi/power.c:222:9: error: 'cur_state' may be used uninitialized in this function [-Werror=maybe-uninitialized]
This sets the variable to zero at the start of the loop, to ensure that
there is well-defined behavior even for an empty list. This gets rid of
the warning.
The warning first showed up when the -Os flag got removed in a bug fix
patch in linux-4.11-rc5.
I would suggest merging this addon patch on top of that bug fix to avoid
introducing a new warning in the stable kernels.

The recent introduced MQ IO scheduler breaks mtip32xx in the
following way.
mtip32xx use the 'request_index' passed to .init_request() as
hardware tag index for initializing hardware queue, and it
actually require that rq->tag is always same with 'request_index'
passed to .init_request(). Current blk-mq IO scheduler can't
guarantee this point, so this patch passes BLK_MQ_F_NO_SCHED
and at least make mtip32xx working.
This patch fixes the following strange hardware failure. The
issue can be triggered easily when doing I/O with mq-deadline
enabled.

Commit 7613c922315e308a ("backlight: pwm_bl: Move the checks for initial
power state to a separate function") not just moved some code, but made
slight changes in semantics.
If a gpiochip doesn't implement the optional .get_direction() callback,
gpiod_get_direction always returns -EINVAL, which is never equal to
GPIOF_DIR_IN, leading to the GPIO not being configured for output.
To avoid this, invert the test and check for not GPIOF_DIR_OUT instead,
like the original code did.
This restores the display on r8a7740/armadillo.

Currently the snapshot trigger enables the probe and then allocates the
snapshot. If the probe triggers before the allocation, it could cause the
snapshot to fail and turn tracing off. It's best to allocate the snapshot
buffer first, and then enable the trigger. If something goes wrong in the
enabling of the trigger, the snapshot buffer is still allocated, but it can
also be freed by the user by writting zero into the snapshot buffer file.
Also add a check of the return status of alloc_snapshot().

The driver uses both u64 and sector_t to refer to offsets, and assigns between the
two. This causes one harmless warning when sector_t is 32-bit:
drivers/lightnvm/pblk-rb.c: In function 'pblk_rb_write_entry_gc':
include/linux/lightnvm.h:215:20: error: large integer implicitly truncated to unsigned type [-Werror=overflow]
drivers/lightnvm/pblk-rb.c:324:22: note: in expansion of macro 'ADDR_EMPTY'
As the driver is already doing this inconsistently, changing the type
won't make it worse and is an easy way to avoid the warning.

We rely on symbol->name[0] since the beginning of tools/perf/, never
having received any complaint about it, also all the containers build
perf just fine, so remove this git codebase remnant.

Since it uses EINVAL unconditionally, it needs to also unconditionally
include errno.h.
Detected when recent changes made errno.h not be included by chance when
tools/perf/arch/arm64/util/unwind-libunwind.c gets included by
tools/perf/util/libunwind/arm64.c.
Putting this changeset just before that change so that we don't lose
bisectability on arm64.

This driver adds support for parsing SBSA Generic Watchdog timer
in GTDT, parse all info in SBSA Generic Watchdog Structure in GTDT,
and creating a platform device with that information.
This allows the operating system to obtain device data from the
resource of platform device. The platform device named "sbsa-gwdt"
can be used by the ARM SBSA Generic Watchdog driver.
