ACPICA commit d1b7372c7eb89cdba3d3c239fb07e2fdc5abf880
This is a regression fix, restoring usage macro to its original
implementation.
There is an issue for usage macros, if an command line option changed
acpi_gbl_debug_file, then the follow up usage message may be errornously
dumped to the debug file.
This is just a bug in theory, because currently acpi_gbl_debug_file can only
be modified by acpibin and acpiexec. And this will not trigger such issue
because:
1. For acpibin, acpi_gbl_debug_file will be modified by "-t" option and the
program exits after processing this option without dumping help message
or other error options.
2. For acpiexec, acpi_gbl_debug_file will only be modified by the open
command, which happens after parsing the command line options, so no
help message will be dumped into the debug file.
But maintaining this logic is difficult, so this patch modifies
acpi_os_printf() into printf() for usage macros so that the help messages are
ensured to be dumped to the stdout. Lv Zheng.

This patch adds sprintf()/snprintf()/vsnprintf()/printf()/vfprintf()
support for OSPMs that have ACPI_USE_SYSTEM_CLIBRARY defined but do not
have ACPI_USE_STANDARD_HEADERS defined.
-iwithprefix include is required to include <stdarg.h> which contains
compiler specific implementation of vargs when -nostdinc is specified.
-fno-builtin is required for GCC to avoid optimization performed printf().
This optimization cannot be automatically disabled by specifying -nostdlib.
Please refer to the first link below for the details. However, the build
option changes do not affect Linux kernel builds and are not included.

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.

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.

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.

There is a lock order issue in acpi_load_tables(). The namespace lock
is held before holding the interpreter lock.
With ACPI_MUTEX_DEBUG enabled in the kernel, this is printed to the
log during boot:
[ 0.885699] ACPI Error: Invalid acquire order: Thread 405884224 owns [ACPI_MTX_Namespace], wants [ACPI_MTX_Interpreter] (20160422/utmutex-263)

[ 0.894019] ACPI Error: Could not release AML Interpreter mutex (20160422/exutils-133)
The issue has been introduced by the following commit:
Commit: 2f38b1b16d
ACPICA Commit: bfe03ffcde8ed56a7eae38ea0b188aeb12f9c52e
Subject: ACPICA: Namespace: Fix a regression that MLC support triggers
dead lock in dynamic table loading
Which fixed a deadlock issue for acpi_ns_load_table() in
acpi_ex_add_table() but didn't take care of the lock order in
acpi_ns_load_table() correctly.
Originally (before the above commit), ACPICA used the
namespace/interpreter locks in the following 2 key code
paths:
1. Table loading:
acpi_ns_load_table
L(Namespace)
acpi_ns_parse_table
acpi_ns_one_complete_parse
U(Namespace)
2. Object evaluation:
acpi_ns_evaluate
L(Interpreter)
acpi_ps_execute_method
U(Interpreter)
acpi_ns_load_table
L(Namespace)
U(Namespace)
acpi_ev_initialize_region
L(Namespace)
U(Namespace)
address_space.setup
L(Namespace)
U(Namespace)
address_space.handler
L(Namespace)
U(Namespace)
acpi_os_wait_semaphore
acpi_os_acquire_mutex
acpi_os_sleep
L(Interpreter)
U(Interpreter)
During runtime, while acpi_ns_evaluate is called, the lock order is
always Interpreter -> Namespace.
In turn, the problematic commit acquires the locks in the following
order:
3. Table loading:
acpi_ns_load_table
L(Namespace)
acpi_ns_parse_table
L(Interpreter)
acpi_ns_one_complete_parse
U(Interpreter)
U(Namespace)
To fix the lock order issue, move the interpreter lock to
acpi_ns_load_table() to ensure the lock order correctness:
4. Table loading:
acpi_ns_load_table
L(Interpreter)
L(Namespace)
acpi_ns_parse_table
acpi_ns_one_complete_parse
U(Namespace)
U(Interpreter)
However, this doesn't fix the current design issues related to the
namespace lock. For example, we can notice that in acpi_ns_evaluate(),
outside of acpi_ns_load_table(), the namespace objects may be created
by the named object creation control methods. And the creation of
the method-owned namespace objects are not locked by the namespace
lock. This patch doesn't try to fix such kind of existing issues.

The new module-level code (MLC) approach invokes MLC on the per-table
basis, but the dynamic loading support of this is incorrect because
of the lock order:
acpi_ns_evaluate
acpi_ex_enter_intperter
acpi_ns_load_table (triggered by Load opcode)
acpi_ns_exec_module_code_list
acpi_ex_enter_intperter

before invoking MLC. However, the unlocking is done to the
acpi_ns_load_table(), in which the interpreter lock should be locked
by acpi_ns_parse_table() but it wasn't.

The address check in acpi_hw_get_access_bit_width() should be byte width
based, not bit width based. This patch fixes this mistake.
For those who want to review acpi_hw_access_bit_width(), here is the
concerns and the design details of the function:
It is supposed that the GAS Address field should be aligned to the byte
width indicated by the GAS AccessSize field. Similarly, for the old non
GAS register, it is supposed that its Address should be aligned to its
Length.
For the "AccessSize = 0 (meaning ANY)" case, we try to return the maximum
instruction width (64 for MMIO or 32 for PIO) or the user expected access
bit width (64 for acpi_read()/acpi_write() or 32 for acpi_hw_read()/
acpi_hw_write()) and it is supposed that the GAS Address field should
always be aligned to the maximum expected access bit width (otherwise it
can't be accessed using ANY access bit width).
The problem is in acpi_tb_init_generic_address(), where the non GAS
register's Length is converted into the GAS BitWidth field, its Address is
converted into the GAS Address field, and the GAS AccessSize field is left
0 but most of the registers actually cannot be accessed using "ANY"
accesses.
As a conclusion, when AccessSize = 0 (ANY), the Address should either be
aligned to the BitWidth (wrong conversion) or aligned to 32 for PIO or 64
for MMIO (real GAS). Since currently, max_bit_width is 32, then:
1. BitWidth for the wrong conversion is 8,16,32; and
2. The Address of the real GAS should always be aligned to 8,16,32.
The address alignment check to exclude false matched real GAS is not
necessary. Thus this patch fixes the issue by removing the address
alignment check.
On the other hand, we in fact could use a simpler check of
"reg->bit_width < max_bit_width" to exclude the "BitWidth=64 PIO" case that
may be issued from acpi_read()/acpi_write() in the future.

For Access Size = 0, it actually can use user expected access bit width.
This patch implements this.
Besides of the ACPICA upstream commit, this patch also includes a fix fixing
the issue reported by the FreeBSD community.
The old register descriptors are translated in acpi_tb_init_generic_address()
with access_width being filled with 0. This breaks code in
acpi_hw_get_access_bit_width() when the registers are 16-bit IO ports and their
bit_width fields are filled with 16. The rapid fix is meant to make code
written for acpi_hw_get_access_bit_width() regression safer before the issue is
correctly fixed from acpi_tb_init_generic_address(). Reported by

ACPICA commit b2294cae776f5a66a7697414b21949d307e6856f
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.

ACPICA commit f005ee6b90d152c1f499efcca6b771a93903cb55
This patch splits \_SB._INI evaluation from device initialization code, so
that it can be performed before PCI_Config _REG evaluations. This is
required for the device enumeration process. Some named objects are
initialized in \_SB._INI and PCI_Config _REG evaluations may use
uninitialized named objects because of the order issue.
This must be fixed before fixing ECDT order issue. There are existing
tables allowing ECDT EC to be used for the entire device enumeration
process, but the enabling of ECDT EC is done in \_SB._INI. Thus \_SB._INI
must be the first control method evaluated in the device enumeration
process. Normally, the order should be automatically ensured by the device
enumeration process itself (for example, PCI_Config _REGs are evaluated by
the PCI bus driver when the driver is probed by the enumeration process),
but since the process is split on Linux (partially done in Linux, partially
done in ACPICA), we need to ensure this with special logics in order to be
regression safe. Lv Zheng.

ACPICA commit c508f8592efaa0d8197f26d7fee6382c5ac8e383
Current code flow cannot ensure _REG association can happen after the
namespace is initialized, so we move _REG association to where _REG was
about to run to fix this issue.
This issue is detected when acpi_ev_initialize_region() is invoked during
the table loading. And this is one of the most important the root cause why
ACPICA table loading is split into 2 load passes. Lv Zheng.

Some compilers require parentheses to be enforced in the macro definition,
so that the macro caller side can be simpler.

If the definition of a control method cannot be found (probably it
is in another module/SSDT), the disassembler must try to guess
at the number of arguments to that method. This change improves
the guessing heuristic.

ACPICA commit 795e136d2ac77c1c8b091fba019b5fe36a44a323
Fixes a problem with the merger of the two internal versions
of this function. Make the maximum integer width (32-bit or
64-bit) a parameter to the function so that it no longer
exclusively uses the integer width specified in the DSDT/SSDT.
