When the ACPI UC error notifier gets called and ARS_REQ bit is set
with the passed in flag, we can receive -EBUSY if ARS_REQ bit is already
set for the nfit_spa->ars_state. When that happens, the ARS request is
dropped. That can potentially cause us to miss the unreported errors that
the on going ARS request does not receive. Add an ARS_REQ_REDO state that
will request short ARS upon ARS completion to grab any errors we missed.

The _LSR method indicates locked status via error-code-3 returned in the
_LSR payload. When any error is returned the payload of _LSR is
truncated to a zero-length buffer.
The _DSM path in comparison allows system software to retrieve the
locked status *and* namespace label area contents.

"Fix recent menuconfig breakage causing it to present ACPI-specific

My fix for a recursive Kconfig dependency caused another issue where the
ACPI specific options end up in the top-level menu in 'menuconfig'. This
was an unintended side-effect of having a silent option between
'menuconfig ACPI' and 'if ACPI'.
Moving the ARCH_SUPPORTS_ACPI symbol ahead of the ACPI menu solves that
problem and restores the previous presentation.

This is unnecessary and triggers a warning in the hypervisor.
Often systems have more processor entries in their ACPI tables than are
actually installed/active. The ACPI_STA_DEVICE_PRESENT bit cannot be
reliably used, but the ACPI_MADT_ENABLED bit can. In order to not
introduce new functions in the main ACPI processor driver code, simply
use acpi_get_phys_id(), which does more than we need, but which checks
the MADT enabled bit in the process. Any CPU for which we can't
determine the APIC ID is unlikely to work properly anyway, so the extra
checks done by acpi_get_phys_id() should do no harm.

Commit fa85015c0d95 (ACPICA: Clear status of all events when entering
S5) made the sleep state entry code in ACPICA clear the status of all
ACPI events when entering S5 to fix a functional regression reported
against commit 18996f2db918 (ACPICA: Events: Stop unconditionally
clearing ACPI IRQs during suspend/resume). However, it is reported
now that the regression also affects system states other than S5 on
some systems and causes them to wake up from sleep prematurely.
For this reason, make the code in question clear the status of all
ACPI events when entering all sleep states (in addition to S5) to
avoid the premature wakeups (this may cause some wakeup events to
be missed in theory, but the likelihood of that is small and the
change here simply restores the previous behavior of the code).

Field elements listed in the init file used to be initialized after
the table load and before executing module-level code blocks. The
recent changes in module-level code mean that the table load becomes
a method execution. If fields are used within module-level code and
we are executing with -fi option, then these values are populated
after the table has finished loading. This commit changes the
initialization of objects listed in the init file so that field unit
values are populated during the table load.

Pull arm64 updates from Will Deacon:
"A bunch of good stuff in here. Worth noting is that we've pulled in
the x86/mm branch from -tip so that we can make use of the core
ioremap changes which allow us to put down huge mappings in the
vmalloc area without screwing up the TLB. Much of the positive
diffstat is because of the rseq selftest for arm64.
Summary:
- Wire up support for qspinlock, replacing our trusty ticket lock
code
- Add an IPI to flush_icache_range() to ensure that stale
instructions fetched into the pipeline are discarded along with the
I-cache lines
- Support for the GCC "stackleak" plugin
- Support for restartable sequences, plus an arm64 port for the
selftest
- Kexec/kdump support on systems booting with ACPI
- Rewrite of our syscall entry code in C, which allows us to zero the
GPRs on entry from userspace
- Support for chained PMU counters, allowing 64-bit event counters to
be constructed on current CPUs
- Ensure scheduler topology information is kept up-to-date with CPU
hotplug events
- Re-enable support for huge vmalloc/IO mappings now that the core
code has the correct hooks to use break-before-make sequences
- Miscellaneous, non-critical fixes and cleanups"

Kconfig reports a warning on x86 builds after the ARM64 dependency
was added.
drivers/acpi/Kconfig:6:error: recursive dependency detected!
drivers/acpi/Kconfig:6: symbol ACPI depends on EFI
This rephrases the dependency to keep the ARM64 details out of the
shared Kconfig file, so Kconfig no longer gets confused by it.
For consistency, all three architectures that support ACPI now
select ARCH_SUPPORTS_ACPI in exactly the configuration in which
they allow it. We still need the 'default x86', as each one
wants a different default: default-y on x86, default-n on arm64,
and always-y on ia64.

As Ard suggested, CONFIG_ACPI && !CONFIG_EFI doesn't make sense on arm64,
while CONFIG_ACPI and CONFIG_CPU_BIG_ENDIAN doesn't make sense either.
As CONFIG_EFI already has a dependency of !CONFIG_CPU_BIG_ENDIAN, it is
good enough to add a dependency of CONFIG_EFI to avoid any useless
combination of configuration.
This bug, reported by Will, will be revealed when my patch series,
"arm64: kexec,kdump: fix boot failures on acpi-only system," is applied
and the kernel is built under allmodconfig.

Specifics:
- Revert two ACPICA commits that are not needed any more (Erik
Schmauss).
- Rework property graph support in the ACPI device properties
framework to make it behave more like the analogous DT code and
update the documentation of it (Sakari Ailus).

ACPI_STA_DEFAULT instead of 0 (Hans de Goede).
- Add a special platform driver for enumerating multiple I2C devices
hooked up to the same object in the ACPI tables (Hans de Goede).
- Fix the ACPI battery driver to avoid reporting full capacity on
systems without support for that and clean it up (Hans de Goede,
Dmitry Rozhkov, Lucas Rangit Magasweran).
- Add two system wakeup quirks to the ACPI EC driver (Aaron Ma, Mika
Westerberg).
- Add the touchscreen on Dell Venue Pro 7139 to the list of "always
present" devices to make it work (Tristian Celestin).
- Revert a special tables handling quirk for Dell XPS 9570 and
Precision M5530 which is not needed any more (Kai Heng Feng).
- Add support for a new OEM _OSI string to allow system vendors to
work around issues with NVidia HDMI audio (Alex Hung).
- Prevent the ACPI button driver from reporting excessive system
wakeup events and clean it up (Ravi Chandra Sadineni, Randy
Dunlap).
- Clean up two minor code style issues in the ACPI core and GHES
handling on ARM64 (Dongjiu Geng, John Garry, Tom Todd)"

Some ThinkPad systems have a power-saving feature that turns off HDMI
audio device in Windows, but NVidia Linux driver does not support this
feature. As a result, HDMI audio will not work on Linux.
A BIOS workaround is added with an OEM_OSI string
"Linux-Lenovo-NV-HDMI-Audio" to power on NVidia HDMI audio when booting.
The form of the OEM _OSI strings is defined by each OEMs and is
discussed in Documentation/acpi/osi.txt.

full_charge_capacity
On some devices (with a buggy _BIX implementation) full_charge_capacity
always reports as 0. This means that our energy_full sysfs attribute will
also always be 0, which is not useful to export.
Worse we calculate our reported capacity on full_charge_capacity and if it
is 0 we always report 0. This causes userspace to immediately shutdown or
hibernate the laptop since it assumes that the battery is critically low.
This commit makes us not report energy_full[_design] or capacity on such
broken devices, avoiding the immediate shutdown / hibernate from userspace.

Simple conditions without negations inflict less cognitive load
on readers.
Rework conditional branches not to use negations. Also add braces
around single statement branches where their counterpart else-branches
consist of more than one statement as suggested in the paragraph 3 of

On removal battery_present changes from 1 to 0 after calling
acpi_battery_get_status() and battery->update_time is set to 0
before returning.
On insertion battery_present changes from 0 to 1 after calling
acpi_battery_get_status() and acpi_battery_get_info() is called
because battery->update_time is 0.
The old_present condition is therefore redundant.
This was added in the commit below when there was a path without
sysfs that would skip getting the newly inserted battery info.

Because acpi_lid_initialize_state() is called on every system
resume and it triggers acpi_lid_notify_state() which invokes
acpi_pm_wakeup_event() for the lid device, the lid's wakeup count is
incremented even if the lid was not the source of the event that woke up
the system. That behavior confuses user space deamons using
wakeup_count to identify the potential system wakeup source. To avoid
the confusion, only trigger acpi_pm_wakeup_event() in the
acpi_button_notify() path and don't do that in the
acpi_lid_initialize_state() path.

Commit 2c4d6baf1bc4 (ACPI / EC: Use ec_no_wakeup on more Thinkpad X1
Carbon 6th systems) changed the DMI table to match all systems where
DMI product family is "Thinkpad X1 Carbon 6th". However, the system I
have here has this string written differently (ThinkPad vs. Thinkpad)
which makes the match fail.
In addition to that, after BIOS upgrade Robin now has the same string
than my system has (perhaps newer BIOS has changed the string).
In any case add another DMI entry to acpi_ec_no_wakeup[] table hopefully
covering all the X1 Carbon 6th systems out there.

Like on X1C6, on X1Y3 EC interrupts constantly wake up system from
s2idle, the power consumption is extremely high.
So make ec_no_wakeup be true as default to keep system in s2idle mode
and reduce power consumption.
Power button works when ec_no_wakeup=true.

Implement references to non-device nodes using the first package
entry in the hierarchical data extension reference, the second one
being the name of the referred object.
The data node references are parsed just after the device arguments
before the integer arguments. If there are no strings after the
device arguments, the parsing works exactly as it used to be.
Referring to a data node called "node" under device DEV, with
integer arguments 0, 2 would thus look like:
Package() { DEV, "node", 0, 2 }

2) allow making references to nodes other than device nodes in ACPI.

just 32-bit.
