libpci 3.3.0 introduced an additional member in the pci_filter struct
which needs to be initialized to -1 to get the same behavior as before
the API change. The libpci internal helpers got updated accordingly,
but as the cpupower pci helpers initialized the struct themselves the
behavior changed.
Use the libpci helper pci_filter_init() to fix this and guard against
similar breakages in the future.
This fixes probing of the AMD fam12h/14h cpuidle monitor on systems
with libpci >= 3.3.0.

I keep seeing
drivers/cpufreq/intel_pstate.c: In function ‘intel_pstate_init’:
drivers/cpufreq/intel_pstate.c:1187:26: warning: initialization from incompatible pointer type
struct cpuinfo_x86 *c = &boot_cpu_data;
when doing randconfig builds.
This is caused by the fact that when !CONFIG_SMP, asm/processor.h
defines cpu_info to boot_cpu_data and the local variable
struct cpu_defaults *cpu_info
overshadows it leading to this unfortunate assignment in the
preprocessed source:
struct cpu_defaults *boot_cpu_data;
struct cpuinfo_x86 *c = &boot_cpu_data;
Rename the local variable and use static_cpu_has_safe() which alleviates
the need for defining a local cpuinfo_x86 pointer.

Change the setpoint for the Baytrail and Cherrytrail CPUs. This
will cause more aggressive pstate selection and improves
performance on a variety of workloads with little power penalty.

Pull ACPICA updates from Rafael Wysocki:
"This updates the kernel's ACPICA code to upstream revision 20150410
and adds a fix for a GPE handling regression introduced during the
3.19 cycle on top of that.
Included are two stable-candidate bug fixes (one of them fixing a 3.16
regression), multiple other fixes and a bunch of cleanups.
Specifics:
- Fix for a GPE handling regression on Dell Latitude D600 that caused
GPE signaling to stop working on that machine, which appears to be
due to a hardware glitch, but it used to work and it can be made
work again in a relativly straightforward way (Rafael J Wysocki).
- Fix for a mutex unlock regression related to the handling of ACPI
tables introduced during the 3.16 development cycle (Octavian
Purdila).
- _REV modification to always return 2 which has been done by all
versions of Windows since NT and the firmware people started to use
it to distinguish between OSes in their AML and do some silly and
wrong things on that basis (Bob Moore).
- Fixes and cleanups related to the acpi_physicall_address data type
including one stable-candidate fix for an issue occasionally
occuring on 64-bit machines running 32-bit kernels where using
offsets provided by the firmware may lead to address overflows (Lv
Zheng).
- External() opcode support infrastructure needed for recompiling
disassembled ACPI tables in some cases including interpreter
modification to ignore that opcode (Bob Moore).
- Support for the "Windows 2015" string in _OSI (Bob Moore).
- GPE debug interface change to return values read from hardware
registers (Lv Zheng).
- Removal of the __DATE__ macro usage in tools (Rasmus Villemoes).
- Assorted minor fixes and cleanups (Lv Zheng, Rickard Strandqvist,
Bob Moore)"

It is reported that ACPI interrupts do not work any more on
Dell Latitude D600 after commit c50f13c672df (ACPICA: Save
current masks of enabled GPEs after enable register writes).
The problem turns out to be related to the fact that the
enable_mask and enable_for_run GPE bit masks are not in
sync (in the absence of any system suspend/resume events)
for at least one GPE register on that machine.
Address this problem by writing the enable_for_run mask into
enable_mask as soon as enable_for_run is updated instead of
doing that only after the subsequent register write has
succeeded. For consistency, update acpi_hw_gpe_enable_write()
to store the bit mask to be written into the GPE register
in enable_mask unconditionally before the write.
Since the ACPI_GPE_SAVE_MASK flag is not necessary any more after
that, drop it along with the symbols depending on it.

ACPICA commit 6853da4c0a99b49d62d6c58d22956cd6ff5759a9
The following commit has fixed local printf issue in width.prec:
Commit: 3589b8b8af6bdc3aafe520d76a73b77d965006b6
Subject: ACPICA: Utilities: Fix local printf issue.
But this commit only resets width/precision/quialifier to fix the reported
issue and doesn't fix other states issues. So now we still can see breakage
in format types and integer bases.
This patch resets format type/base states for local printf to fix this
issue. Lv Zheng.
Linux kernel is not affected by this patch as acpi_ut_vsnprintf() hasn't
been enabled in the kernel.

ACPICA commit 7af00219681ab35ebe57d64a9189fd04a5a026d8
Windows uses a value of 2, and has no plans to ever change this. So, _REV is
essentially useless for its primary purpose.
Worse, some BIOS vendors have used the difference in _REV values between
Windows and ACPICA to indicate which one is running.
It has been decided by the ACPI community to deprecate this method, and return
1 for ACPI 1.0 (32-bit integers) and 2 for ACPI 2.0 and greater (both 32-bit
and 64-bit integers.
ACPICA is changed to reflect this.

ACPICA commit d115fe2ffdab449d6107d58580c5afd0a81d65fe
This change adds the basic low-level infrastructure for the External
AML opcode. The interpreter will simply ignore this op, as the op
is intended for use by the disassembler only.
Note that External() opcode is useful for disassembler, interpreter
can simply ignore it and still return exceptions for unknown control
methods so the kernel part only includes the grammar definition of
External() opcode in order to ignore it but doesn't interpret it.

ACPICA commit f5d2ff3fa05341d9fe27250fcb2e14c7f871432c
For dynamically loaded tables that have unknown ACPI signatures,
this option (-df) forces the disassembler to treat the table as if
it contains valid AML code (like a DSDT or SSDT). Otherwise, the
disassembler will treat the table as an unkown data table and
simply do a hex dump of the table.

ACPICA commit 6eb364d790dd103bd4990f808e0095a421c437cb
acpi_tb_store_table() implements a logic that is only correct to iasl. So it
won't be used by any other utilities except iasl. This function is
complained by the kernel users as an unused function. The best choice to
stop releasing it to the Linux kernel should be moving it to adisasm.c.
ACPI table manager can use both struct acpi_table_desc (direct referencing)
and table index (indirect referencing) as the descriptor to the table, so
acpi_tb_get_next_root_index() is extended to return both of them to allow
maximum usability from the callers. NOTE that indirect referencing is a
design result to meet the boot stage static allocation requirement for the
table descriptors.
This is a linuxized acpi_tb_store_table() removing result, there should be
no functional changes introduced to the Linux kernel by this patch except
the additonal kernel unused argument for acpi_tb_get_next_root_index()
(renamed to acpi_tb_get_next_root_index()). This argument is used in the
ACPICA upstream.

GPE and fixed event.
ACPICA commit e25d791e4b3d5b9f4ead298269610cb05f89749a
There is a facility in Linux, developers can obtain GPE and fixed event
status via /sys/firmware/interrupts/. This is implemented using
acpi_get_event_status() and acpi_get_gpe_status(). Recently while debugging some
GPE race issues, it is found that the facility is lacking in the ability to
obtain real hardware register values, the confusing information makes
debugging difficult.
This patch modifies acpi_get_gpe_status() to return EN register values to fix
this gap. Then flags returned from acpi_get_event_status() and
acpi_get_gpe_status() are also cleaned up to reflect this change.
The old ACPI_EVENT_FLAG_SET is carefully kept to avoid regressions. It can
be deleted after we can make sure all its references are removed from OSPM
code. Lv Zheng.

ACPICA commit aacf863cfffd46338e268b7415f7435cae93b451
It is reported that on a physically 64-bit addressed machine, 32-bit kernel
can trigger crashes in accessing the memory regions that are beyond the
32-bit boundary. The region field's start address should still be 32-bit
compliant, but after a calculation (adding some offsets), it may exceed the
32-bit boundary. This case is rare and buggy, but there are real BIOSes
leaked with such issues (see References below).
This patch fixes this gap by always defining IO addresses as 64-bit, and
allows OSPMs to optimize it for a real 32-bit machine to reduce the size of
the internal objects.
Internal acpi_physical_address usages in the structures that can be fixed
by this change include:
1. struct acpi_object_region:
acpi_physical_address address;
2. struct acpi_address_range:
acpi_physical_address start_address;
acpi_physical_address end_address;
3. struct acpi_mem_space_context;
acpi_physical_address address;
4. struct acpi_table_desc
acpi_physical_address address;
See known issues 1 for other usages.
Note that acpi_io_address which is used for ACPI_PROCESSOR may also suffer
from same problem, so this patch changes it accordingly.
For iasl, it will enforce acpi_physical_address as 32-bit to generate
32-bit OSPM compatible tables on 32-bit platforms, we need to define
ACPI_32BIT_PHYSICAL_ADDRESS for it in acenv.h.
Known issues:
1. Cleanup of mapped virtual address
In struct acpi_mem_space_context, acpi_physical_address is used as a virtual
address:
acpi_physical_address mapped_physical_address;
It is better to introduce acpi_virtual_address or use acpi_size instead.
This patch doesn't make such a change. Because this should be done along
with a change to acpi_os_map_memory()/acpi_os_unmap_memory().
There should be no functional problem to leave this unchanged except
that only this structure is enlarged unexpectedly.

ACPICA commit b60612373a4ef63b64a57c124576d7ddb6d8efb6
For physical addresses, since the address may exceed 32-bit address range
after calculation, we should use 0x%8.8X%8.8X instead of ACPI_PRINTF_UINT
and ACPI_FORMAT_UINT64() instead of
ACPI_FORMAT_NATIVE_UINT()/ACPI_FORMAT_TO_UINT().
This patch also removes above replaced macros as there are no users.
This is a preparation to switch acpi_physical_address to 64-bit on 32-bit
kernel builds.

ACPI_PHYSADDR_TO_PTR()/ACPI_PTR_TO_PHYSADDR().
ACPICA commit 154f6d074dd38d6ebc0467ad454454e6c5c9ecdf
There are code pieces converting pointers using "(acpi_physical_address) x"
or "ACPI_CAST_PTR (t, x)" formats, this patch cleans up them.
Known issues:
1. Cleanup of "(ACPI_PHYSICAL_ADDRRESS) x" for a table field
For the conversions around the table fields, it is better to fix it with
alignment also fixed. So this patch doesn't modify such code. There
should be no functional problem by leaving them unchanged.

Let's show locks which are associated with a file descriptor in
its fdinfo file.
Currently we don't have a reliable way to determine who holds a lock. We
can find some information in /proc/locks, but PID which is reported there
can be wrong. For example, a process takes a lock, then forks a child and
dies. In this case /proc/locks contains the parent pid, which can be
reused by another process.
$ cat /proc/locks
...
6: FLOCK ADVISORY WRITE 324 00:13:13431 0 EOF
...
$ ps -C rpcbind
PID TTY TIME CMD
332 ? 00:00:00 rpcbind
$ cat /proc/332/fdinfo/4
pos: 0
flags: 0100000
mnt_id: 22
lock: 1: FLOCK ADVISORY WRITE 324 00:13:13431 0 EOF
$ ls -l /proc/332/fd/4
lr-x------ 1 root root 64 Mar 5 14:43 /proc/332/fd/4 -> /run/rpcbind.lock
$ ls -l /proc/324/fd/
total 0
lrwx------ 1 root root 64 Feb 27 14:50 0 -> /dev/pts/0
lrwx------ 1 root root 64 Feb 27 14:50 1 -> /dev/pts/0
lrwx------ 1 root root 64 Feb 27 14:49 2 -> /dev/pts/0
You can see that the process with the 324 pid doesn't hold the lock.
This information is required for proper dumping and restoring file
locks.

The RTC driver supports two flavors of S5M devices: S5M8767-like and
S2MPS14-like.
On S2MPS13 and S2MPS14 devices the RTC module is the same so we want to
re-use the existing support of S2MPS14. However device type was passed
from parent MFD driver in platform data structure. This way for the
S2MPS13 device the main MFD driver passed device type of 'S2MPS13X'.
Instead decouple detecting of device type between main MFD and RTC driver.
This allows adding support for other S2MPS14 variations (like S2MPS11 and
S2MPS13) easily by adding to mfd/sec-core.c:
static const struct mfd_cell s2mps13_devs[] = {
{ .name = "s2mps14-rtc", }
};

The mm->exe_file is currently serialized with mmap_sem (shared) in order
to both safely (1) read the file and (2) compute the realpath by calling
tomoyo_realpath_from_path, making it an absolute overkill. Good users
will, on the other hand, make use of the more standard get_mm_exe_file(),
requiring only holding the mmap_sem to read the value, and relying on
reference

In the future mm->exe_file will be done without mmap_sem serialization,
thus isolate and reorganize the related code to make the transition
easier. Good users will, make use of the more standard get_mm_exe_file(),
requiring only holding the mmap_sem to read the value, and relying on
reference counting to make sure that the exe file won't dissappear
underneath us while getting the dcookie.

sync_buffer() needs the mmap_sem for two distinct operations, both only
occurring upon user context switch handling:
1) Dealing with the exe_file.
2) Adding the dcookie data as we need to lookup the vma that
backs it. This is done via add_sample() and add_data().
This patch isolates 1), for it will no longer need the mmap_sem for
serialization. However, for now, make of the more standard
get_mm_exe_file(), requiring only holding the mmap_sem to read the value,
and relying on reference counting to make sure that the exe file won't
dissappear underneath us while doing the get dcookie.
As a consequence, for 2) we move the mmap_sem locking into where we really
need it, in lookup_dcookie(). The benefits are twofold: reduce mmap_sem
hold times, and cleaner code.

This modifies the IP32 (SGI O2) platform and reset code to utilize the new
rtc-ds1685 driver. The old mc146818rtc.h header is removed and ip32_defconfig
is updated as well.
