====================
sfc: SFN8000 support improvements

This series improves support for the recently released SFN8000 series
of adapters. Specifically, it retrieves interrupt moderation timer
settings directly from the adapter and uses those settings. It also
uses a new event queue initialisation interface, allowing specification
of a performance objective rather than enabling individual flags.

d95e329a55 sfc: get timer configuration from adapter
On SFN8000 series adapters the MC provides a method to get the timer
quantum and the maximum timer setting. We revert to the old values if the
new call is unavailable.

539de7c524 sfc: set interrupt moderation via MCDI
SFN8000-series NICs require a new method of setting interrupt moderation,
via MCDI. This is indicated by a workaround flag. This new MCDI command
takes an explicit time value rather than a number of ticks. It therefore
makes sense to also store the moderation values in terms of time, since
that is what the ethtool interface is interested in.

a995560a27 sfc: use new performance based event queue init
Rather than explicitly specifying flags we can now specify a desired
performance target to the firmware, ie higher throughput or lower latency.
For now we use the default "auto" configuration.

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.

911a9b8428 ACPICA: Applications: Fix a potential issue that help messages may be dumped to acpi_gbl_debug_file
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 d261d40ea168f8e4c4e3986de720b8651c4aba1c

This patch adds sprintf()/snprintf()/vsnprintf()/printf()/vfprintf()

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.

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.

this patch also moves it to acmsvc.h and tunes acwin.h to correctly use
it.

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.

02dcdc3e86 ACPICA: Simplify configuration for "Max Loops" system parameter
ACPICA commit 857c510d70e18eecc275dd3087807a18bae8aa51

Allow for static configuration of this parameter. It is used
to abort out of infinite loops caused by non-response from
hardware.

ACPICA commit 152a8ca2c7fc877d6aff0f9d0965184ef2ddce5c

Opcode 0x15 was added in ACPI 6.0 for disassemblers.
The disassembler by default does not emit the actual opcodes, they
are used internally. Option added for internal debugging only.

This patch doesn't affect Linux kernel as disassembler is not in
the Linux kernel.

ACPICA commit f2d349f8a11efc0f438ad6903564f3a6755dc6b9

The interpreter should never see this opcode (it is used by
disassemblers), so the final implementation is to return an

601bbae0bc dsa: mv88e6xxx: hide unused functions
When CONFIG_NET_DSA_HWMON is disabled, we get warnings about two unused
functions whose only callers are all inside of an #ifdef:

drivers/net/dsa/mv88e6xxx.c:3257:12: 'mv88e6xxx_mdio_page_write' defined but not used [-Werror=unused-function]
drivers/net/dsa/mv88e6xxx.c:3244:12: 'mv88e6xxx_mdio_page_read' defined but not used [-Werror=unused-function]

This adds another ifdef around the function definitions. The warnings
appeared after the functions were marked 'static', but the problem
was already there before that.
