Rafael J. Wysocki ae57857b9b ACPICA: Use uintptr_t and offsetof() in Linux kernel builds
To avoid "performing pointer subtraction with a null pointer has
undefined behavior" compiler warnings, use uintptr_t and offsetof()
that are always available during Linux kernel builds to define
acpi_uintptr_t and the ACPI_TO_INTEGER() and ACPI_OFFSET() macros.

Based on earlier proposal from Arnd Bergmann.

Rafael J. Wysocki 63b0a7b16f ACPI: Drop ACPI_USE_BUILTIN_STDARG ifdef from acgcc.h
The ACPI_USE_BUILTIN_STDARG symbol is never set in the kernel build,
so stop checking it in include/acpi/platform/acgcc.h and drop all of
the macros depending on it (which appear to duplicate the analogous
macros from linux/stdarg.h, but in fact are never used).

Nick Desaulniers c1a7c2ce7c ACPICA: fix -Wfallthrough
ACPICA commit 4b9135f5774caa796ddf826448811e8e7f08ef2f

GCC 7.1 gained -Wimplicit-fallthrough to warn on implicit fallthrough,
as well as __attribute__((__fallthrough__)) and comments to explicitly
denote that cases of fallthrough were intentional. Clang also supports
this warning and statement attribute, but not the comment form.

Robert Moore provides additional context about the lint comments being
removed. They were for "an old version of PC-Lint, which we don't use
anymore." Drop those.

This will help us enable -Wimplicit-fallthrough throughout the Linux
kernel.

acpi_gbl_xgpe1_block_logical_address, respectively, so as to allow
ACPICA to use them for accessing GPE registers in system memory,
instead of using their physical addresses and looking up the

For the kernel-resident ACPICA, optionally be silent about the

it can generate a lot of noise/errors on platforms whose
firmware carries around a bunch of unused Package objects.
To disable these errors, define ACPI_IGNORE_PACKAGE_RESOLUTION_ERRORS
in the OS-specific header.

In order to build ACPICA EFI tools with EDK-II on Windows, 64-bit

Note:
1. This patch also splits _EDK2_EFI from _GNU_EFI as they might have
   different math64 supports.
2. Support of gcc math64 is not included in this patch.
3. Support of EDK2 arch independent math64 is done via linking to base_lib.

Lv Zheng ffab9188e4 ACPICA: Linuxize: Restore and fix Intel compiler build
ACPICA commit b59347d0b8b676cb555fe8da5cad08fcd4eeb0d3

The following commit cleans up compiler specific inclusions:

  Commit: 9fa1cebdbf
  Subject: ACPICA: OSL: Cleanup the inclusion order of the compiler-specific headers

But breaks one thing due to the following old issue:

 Buidling Linux kernel with Intel compiler originally depends on acgcc.h
 not acintel.h.

So after making Intel compiler build working in ACPICA upstream by
correctly using acintel.h, it becomes unable to build Linux kernel using
Intel compiler as there is no acintel.h in the kernel source tree.

This patch releases acintel.h to Linux kernel and fixes its inclusion in
acenv.h.

Lv Zheng 174cc7187e ACPICA: Tables: Back port acpi_get_table_with_size() and early_acpi_os_unmap_memory() from Linux kernel
ACPICA commit cac6790954d4d752a083e6122220b8a22febcd07

This patch back ports Linux acpi_get_table_with_size() and
early_acpi_os_unmap_memory() into ACPICA upstream to reduce divergences.

The 2 APIs are used by Linux as table management APIs for long time, it
contains a hidden logic that during the early stage, the mapped tables
should be unmapped before the early stage ends.

During the early stage, tables are handled by the following sequence:
 acpi_get_table_with_size();
 parse the table
 early_acpi_os_unmap_memory();
During the late stage, tables are handled by the following sequence:
 acpi_get_table();
 parse the table
Linux uses acpi_gbl_permanent_mmap to distinguish the early stage and the
late stage.

The reasoning of introducing acpi_get_table_with_size() is: ACPICA will
remember the early mapped pointer in acpi_get_table() and Linux isn't able to
prevent ACPICA from using the wrong early mapped pointer during the late
stage as there is no API provided from ACPICA to be an inverse of
acpi_get_table() to forget the early mapped pointer.

But how ACPICA can work with the early/late stage requirement? Inside of
ACPICA, tables are ensured to be remained in "INSTALLED" state during the
early stage, and they are carefully not transitioned to "VALIDATED" state
until the late stage. So the same logic is in fact implemented inside of
ACPICA in a different way. The gap is only that the feature is not provided
to the OSPMs in an accessible external API style.

It then is possible to fix the gap by providing an inverse of
acpi_get_table() from ACPICA, so that the two Linux sequences can be
combined:
 acpi_get_table();
 parse the table
 acpi_put_table();
In order to work easier with the current Linux code, acpi_get_table() and
acpi_put_table() is implemented in a usage counting based style:
 1. When the usage count of the table is increased from 0 to 1, table is
    mapped and .Pointer is set with the mapping address (VALIDATED);
 2. When the usage count of the table is decreased from 1 to 0, .Pointer
    is unset and the mapping address is unmapped (INVALIDATED).
So that we can deploy the new APIs to Linux with minimal effort by just
invoking acpi_get_table() in acpi_get_table_with_size() and invoking
acpi_put_table() in early_acpi_os_unmap_memory(). Lv Zheng.

Lv Zheng 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.

Lv Zheng 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.

Lv Zheng 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.

Lv Zheng 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.

Lv Zheng 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.

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.
