34f3a91b3b ACPICA: OSL: Fix a regression that old GCC requires a workaround for strchr()
ACPICA commit be836c36454a624a4fb1d17234080ef8c07993fc

There is a GCC false-warning issue on specific GCC versions that
"strchr" will be preprocessed and extracted to contain
!__buildin_constant_p() checker and it surely is a constant logical
value "1" for strchr() arguments. Then -Wlogical-op errorneously reports a
warning.

The regression is triggered after the standard headers are re-ordered in
the EFI porting task. This patch fixes this regression by moving the
workaround to a new position after including all other standard headers.

9fa1cebdbf ACPICA: OSL: Cleanup the inclusion order of the compiler-specific headers
ACPICA commit a760a98ec84b1ec782e0bff5f6612af6fb89c10c

Originally compiler specific headers are included by the host-specific
headers. This makes build configuration management very inconvenient. And
many inclusion order issues can be hidden accross different host OSes. It
will then likely that some host builds will be broken just because of
fixing some inclusion order issues for other host builds.

This patch splits the compiler-specific header inclusions out of the
host-specific headers so that compiler-specific inclusion order issues will
not get entangled in the host-specific inclusion orders.

Note that intel compiler defines __GNUC__, so this patch contains special
handling because acintel.h and acgcc.h should be mutual exclusive.

e323c02dee ACPICA: MSVC9: Fix <sys/stat.h> inclusion order issue
ACPICA commit 9bb265c2afb9910e46f820d6759648580edabd09

When /Za is specified, headers of some Windows SDKs contain bugs breaking
VC builds, and MSVC9's default SDK is one of such header-buggy library.

In order to solve this issue, many VC developers stop using /Za. However
we've been asked to have this fixed without removing /Za.

In MSVC9 default SDK, this issue can be fixed by restricting <sys/stat.h>
to be the last standard file included by every source file in the projects.
This patch thus moves <sys/stat.h> inclusion to "acapps.h", so that this
issue can be fixed by ensuring that "acapps.h" is always the last standard
file included by all of the ACPICA source files. This is in fact also a
useful cleanup because applications can only include one header (e.x.,
acpidump.h) instead of including acapps.h separately. Lv Zheng.

Except some harmless header inclusion re-ordering, Linux kernel is not
affected by this change.

4e2fc6a0aa ACPICA: Clib/EFI: Fix wrong order of standard integer types/IO handles
ACPICA commit 7f9b359b7c78c69b07f62eb2d58f710c351fd75d

EFI header should use standard C library stuffs (integer types and IO
handles) rather than implementing such standard stuffs.
This patch fixes this issue by:
1. Implementing standard integer types for ACPI_USE_STANDARD_HADERS=n;
2. Defining EFI types using standard integer types and standard IO handles;
3. Tuning header inclusion order and environment definition order;
4. Removing wrong standard header inclusion from ACPICA core files;
5. Moving several application headers from acpidump.h to acenv.h.
This patch corrects some of them. Lv Zheng.

Except some harmless header inclusion re-ordering, Linux kernel is not
affected by this change.

da24f31d33 ACPICA: Clib: Fix wrong mini C library usage
ACPICA commit 4aab18466b56f3660f27cffd3c0160900737f844

When mini C library is used, we should have the following macros undefined.
The only user should be the EFI applications:
  ACPI_USE_SYSTEM_CLIBRARY=n
  ACPI_USE_STANDARD_HEADERS=n
All other applications uses the compiler specific library:
  ACPI_USE_SYSTEM_CLIBRARY=y
  ACPI_USE_STANDARD_HEADERS=y
Linux/BSD kernels are the kind of hosts providing C library but does not
provide the standard headers:
  ACPI_USE_SYSTEM_CLIBRARY=y
  ACPI_USE_STANDARD_HEADERS=n
But the above logic hasn't been synchronized between the header files.

This patch synchronizes all header files to correct C library usages for
different platforms. This patch moves all ACPI_USE_SYSTEM_CLIRARY and
ACPI_USE_STANDARD_HEADERS to the top most lines of a platform specific
header.

After synchronization, ACPI_USE_SYSTEM_CLIRARY definition can be removed
for ACPI_APPLICATION. Lv Zheng.

5fb3ab848b ACPICA: Clib: Cleanup va_arg related code
ACPICA commit 32701b33cdc48d9bc43da8c9274cf172135b68fc

We in fact always use the compiler specific stdarg.h for GCC even
when ACPI_USE_STANDARD_HEADERS is not defined. So that the va_arg usages
can always be correct for different compiler options.

Likewise, the va_arg implemented in acenv.h is actually MSVC specific,
this patch also moves it to acmsvc.h and tunes acwin.h to correctly use
it.

After cleaning up, this patch removes all <stdarg.h> inclusions from
other files, but doesn't touch the BSD headers. Lv Zheng.

2af52c2bd2 ACPICA: Events: Introduce acpi_mask_gpe() to implement GPE masking mechanism
ACPICA commit 23a417ca406a527e7ae1710893e59a8b6db30e14

There is a facility in Linux, developers can control the enabling/disabling
of a GPE via /sys/firmware/acpi/interrupts/gpexx. This is mainly for
debugging purposes.

But many users expect to use this facility to implement quirks to mask a
specific GPE when there is a gap in Linux causing this GPE to flood. This
is not working correctly because currently this facility invokes
enabling/disabling counting based GPE driver APIs:
 acpi_enable_gpe()/acpi_disable_gpe()
and the GPE drivers can still affect the count to mess up the GPE
masking purposes.

However, most of the IRQ chip designs allow masking/unmasking IRQs via a
masking bit which is different from the enabled bit to achieve the same
purpose. But the GPE hardware doesn't contain such a feature, this brings
the trouble.

In this patch, we introduce a software mechanism to implement the GPE
masking feature, and acpi_mask_gpe() are provided to the OSPMs to
mask/unmask GPEs in the above mentioned situation instead of
acpi_enable_gpe()/acpi_disable_gpe(). ACPICA BZ 1102. Lv Zheng.

bd721ea73e treewide: replace obsolete _refok by __ref
There was only one use of __initdata_refok and __exit_refok

__init_refok was used 46 times against 82 for __ref.

Those definitions are obsolete since commit 312b1485fb ("Introduce new
section reference annotations tags: __ref, __refdata, __refconst")

This patch removes the following compatibility definitions and replaces
them treewide.

/* compatibility defines */
#define __init_refok     __ref
#define __initdata_refok __refdata
#define __exit_refok     __ref

I can also provide separate patches if necessary.
(One patch per tree and check in 1 month or 2 to remove old definitions)

Majority of this update is about ASoC, including a few new drivers,
 and the rest are mostly minor changes.  The only substantial change in
 ALSA core is about the additional error handling in the
 compress-offload API.  Below are highlights:
 
 - Add the error propagating support in compress-offload API
 
 - HD-audio: a usual Dell headset fixup, an Intel HDMI/DP fix, and the
   default mixer setup change ot turn off the loopback
 
 - Lots of updates for ASoC Intel drivers, mostly board support and bug
   fixing, and to the NAU8825 driver
 
 - Work on generalizing bits of simple-card to allow more code sharing
   with the Renesas rsrc-card (which can't use simple-card due to DPCM)
 
 - Removal of the Odroid X2 driver due to replacement with simple-card
 
 - Support for several new Mediatek platforms and associated boards

a36a7fecfe ACPI / processor_idle: Add support for Low Power Idle(LPI) states
ACPI 6.0 introduced an optional object _LPI that provides an alternate
method to describe Low Power Idle states. It defines the local power
states for each node in a hierarchical processor topology. The OSPM can
use _LPI object to select a local power state for each level of processor
hierarchy in the system. They used to produce a composite power state
request that is presented to the platform by the OSPM.

Since multiple processors affect the idle state for any non-leaf hierarchy
node, coordination of idle state requests between the processors is
required. ACPI supports two different coordination schemes: Platform
coordinated and  OS initiated.

This patch adds initial support for Platform coordination scheme of LPI.

35ae713355 ACPI / processor_idle: introduce ACPI_PROCESSOR_CSTATE
ACPI 6.0 adds a new method to specify the CPU idle states(C-states)
called Low Power Idle(LPI) states. Since new architectures like ARM64
use only LPIs, introduce ACPI_PROCESSOR_CSTATE to encapsulate all the
code supporting the old style C-states(_CST).

This patch will help to extend the processor_idle module to support
LPI.

613e97218c device property: Add function to search for named child of device
For device nodes in both DT and ACPI, it possible to have named
child nodes which contain properties (an existing example being
gpio-leds). This adds a function to find a named child node for
a device which can be used by drivers for property retrieval.

For DT data node name matching, of_node_cmp() and similar functions
are made available outside of CONFIG_OF block so the new function
can reference these for DT and non-DT builds.

For ACPI data node name matching, a helper function is also added
which returns false if CONFIG_ACPI is not set, otherwise it
performs a string comparison on the data node name. This avoids
using the acpi_data_node struct for non CONFIG_ACPI builds,
which would otherwise cause a build failure.

Follow-on arm64 ACPI/NUMA patches need to map MADT entries very early
(before kmalloc is usable).

Add acpi_map_madt_entry() which, indirectly, uses
early_memremap()/early_memunmap() to access the table and parse out
the mpidr.  The existing implementation of map_madt_entry() is
modified to take a pointer to the MADT as a parameter and the callers

 "The bulk of this update was stabilized before the merge window and

  Not included in this pull request are two dax topic branches (dax
  error handling, and dax radix-tree locking).  These topics were
  deferred to get a few more days of -next integration testing, and to
  coordinate a branch baseline with Ted and the ext4 tree.  Vishal and
  Ross will send the error handling and locking topics respectively in
  the next few days.

  This branch has received a positive build result from the kbuild robot
  across 226 configs.

This patch removes unwanted spaces for typedef. This solution doesn't cover
function types.

Note that the linuxize result of this commit is very giant and should have
many conflicts against the current Linux upstream. Thus it is required to
modify the linuxize result of this commit and the commits around it
manually in order to have them merged to the Linux upstream. Since this is
very costy, we should do this only once, and if we can't ensure to do this
only once, we need to revert the Linux code to the wrong indentation result
before merging the linuxize result of this commit. Lv Zheng.

is_pset_node() need to consider it. Using IS_ERR_OR_NULL()
to check it.

c7e16e5257 acpi: widen acpi_evaluate_dsm() revision and function-index arguments
The ACPI specification states that arguments "Revision ID" and "Function
Index" to a _DSM are type "Integer."  Type Integers are 64 bit
quantities.

The function evaluate_dsm specifies these types as simple "int" which
are 32 bits.  Widen type passed to acpi_evaluate_dsm and its callers and
derived callers to pass correct type.

acpi_check_dsm and acpi_evaluate_dsm_typed had similar issue and were
corrected as well.

This is in preparation for libnvdimm implementing a generic _DSM
passthrough facility to have the capacity to pass 64-bit values as the
ACPI specification allows.
