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.

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.

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.

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.

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.

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.

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.

rename the member, to force old and out-of-tree code to break

care about whether it's a read or a write at that level, just
pass in a bool 'is_write' parameter instead.
Then we can also move op_is_write() and friends back under

Pull documentation fixes from Jonathan Corbet:
"Three fixes for the docs build, including removing an annoying warning
on 'make help' if sphinx isn't present"
* tag 'doc-4.8-fixes' of git://git.lwn.net/linux:
DocBook: use DOCBOOKS="" to ignore DocBooks instead of IGNORE_DOCBOOKS=1
Documenation: update cgroup's document path
Documentation/sphinx: do not warn about missing tools in 'make help'
First off, the intention of this pull is to declare that I'll be the
binfmt_misc maintainer (mainly on the grounds of you touched it last,
it's yours). There's no MAINTAINERS entry, but get_maintainers.pl
will now finger me.
The update itself is to allow architecture emulation containers to
function such that the emulation binary can be housed outside the
container itself. The container and fs parts both have acks from
relevant experts.
The change is user visible. To use the new feature you have to add an
F option to your binfmt_misc configuration. However, the existing
tools, like systemd-binfmt work with this without modification.

"The usual behaviour of binfmt_misc is to spawn the binary lazily when
the misc format file is invoked. However, this doesn't work very well
in the face of mount namespaces and changeroots, so the F mode opens
the binary as soon as the emulation is installed and uses the opened
image to spawn the emulator, meaning it is always available once
installed, regardless of how the environment changes"

In most cases, EPERM is returned on immutable inode, and there're only a
few places returning EACCES. I noticed this when running LTP on
overlayfs, setxattr03 failed due to unexpected EACCES on immutable
inode.
So converting all EACCES to EPERM on immutable inode.

Merge tag 'xfs-rmap-for-linus-4.8-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/dgc/linux-xfs
Pull more xfs updates from Dave Chinner:
"This is the second part of the XFS updates for this merge cycle, and
contains the new reverse block mapping feature for XFS.
Reverse mapping allows us to track the owner of a specific block on
disk precisely. It is implemented as a set of btrees (one per
allocation group) that track the owners of allocated extents.
Effectively it is a "used space tree" that is updated when we allocate
or free extents. i.e. it is coherent with the free space btrees we
already maintain and never overlaps with them.
This reverse mapping infrastructure is the building block of several
upcoming features - reflink, copy-on-write data, dedupe, online
metadata and data scrubbing, highly accurate bad sector/data loss
reporting to users, and significantly improved reconstruction of
damaged and corrupted filesystems. There's a lot of new stuff coming
along in the next couple of cycles,a nd it all builds in the rmap
infrastructure.
As such, it's a huge chunk of new code with new on-disk format
features and internal infrastructure. It warns at mount time as an
experimental feature and that it may eat data (as we do with all new
on-disk features until they stabilise). We have not released
userspace suport for it yet - userspace support currently requires
download from Darrick's xfsprogs repo and build from source, so the
access to this feature is really developer/tester only at this point.
Initial userspace support will be released at the same time kernel
with this code in it is released.
The new rmap enabled code regresses 3 xfstests - all are ENOSPC
related corner cases, one of which Darrick posted a fix for a few
hours ago. The other two are fixed by infrastructure that is part of
the upcoming reflink patchset. This new ENOSPC infrastructure
requires a on-disk format tweak required to keep mount times in
check - we need to keep an on-disk count of allocated rmapbt blocks so
we don't have to scan the entire btrees at mount time to count them.
This is currently being tested and will be part of the fixes sent in
the next week or two so users will not be exposed to this change"
