Pull MIPS updates from Ralf Baechle:
"This is the main pull request for MIPS for Linux 4.1. Most
noteworthy:
- Add more Octeon-optimized crypto functions
- Octeon crypto preemption and locking fixes
- Little endian support for Octeon
- Use correct CSR to soft reset Octeons
- Support LEDs on the Octeon-based DSR-1000N
- Fix PCI interrupt mapping for the Octeon-based DSR-1000N
- Mark prom_free_prom_memory() as __init for a number of systems
- Support for Imagination's Pistachio SOC. This includes arch and
CLK bits. I'd like to merge pinctrl bits later
- Improve parallelism of csum_partial for certain pipelines
- Organize DTB files in subdirs like other architectures
- Implement read_sched_clock for all MIPS platforms other than
Octeon
- Massive series of 38 fixes and cleanups for the FPU emulator /
kernel
- Further FPU remulator work to support new features. This sits on a
separate branch which also has been pulled into the 4.1 KVM branch
- Clean up and fixes for the SEAD3 eval board; remove unused file
- Various updates for Netlogic platforms
- A number of small updates for Loongson 3 platforms
- Increase the memory limit for ATH79 platforms to 256MB
- A fair number of fixes and updates for BCM47xx platforms
- Finish the implementation of XPA support
- MIPS FDC support. No, not floppy controller but Fast Debug Channel :)
- Detect the R16000 used in SGI legacy platforms
- Fix Kconfig dependencies for the SSB bus support"

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)"

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", }
};

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.

The hym8563 datasheet describes the clock output control-bit as "when set
to logic 0, the square wave output is enable, when set to logic 1, the
CLKOUT output is inhibited". But in reality the setting is exactly
opposite.
Before now, the clock output was not really used, but on the rk3288 soc
this generated clock is used to supply the temperature sensor block and
the swapped bit value prevented it from working. With the corrected
value, the tsadc now reports correct values.

register writes
RTC module contains a kicker mechanism to prevent any spurious writes from
changing the register values. This mechanism requires two MMR writes to
the KICK0 and KICK1 registers with exact data values before the kicker
lock mechanism is released.
Currently the driver release the lock in the probe and leaves it enabled
until the rtc driver removal. This eliminates the idea of preventing
spurious writes when RTC driver is loaded. So implement rtc lock and
unlock functions before and after register writes.
This is as advised by Paul to implement lock and unlock functions in the
driver and not to unlock and leave it in probe. The same discussion can
be seen here:

__rtc_read_time logs should be debug logs instead of error logs.
For example, when the RTC clock is not set, it's not really useful
to print a kernel error log every time someone tries to read the clock:
~ # hwclock -r
[ 604.508263] rtc rtc0: read_time: fail to read
hwclock: RTC_RD_TIME: Invalid argument
If there's a real error, it's likely that lower level or higher level
code will tell it anyway. Make these logs debug logs, and also print
the error code for the read failure.

When using device trees on the ARM platform, it is not certain at compile
time whether or not the system will have a RTC.
If one enables CONFIG_HCTOSYS just in case the system booted has a RTC,
and it turns out not to be, this will result in a big fat "unable to open
rtc device" error being printed to console, even when "quiet" is set in
the kernel cmdline.
Fix this by outputting the message with loglevel info instead.

The rtc's status register allows to determine if a 32k crystal is
connected to keep the rtc running in low power states provided the
corresponding fuse bits were blown correctly during production. (In case
they were not, the right frequency can be stated in the device tree.) If
there is no such crystal available force the 24 MHz XTAL clock to keep
running to retain the right date and time. Otherwise use the crystal to
save some power.
It would be nice to only switch to the crystal when the XTAL clock is
about to be disabled and keep the crystal off when unneeded because XTAL
is always on while the chip is powered on. But as sudden power loss isn't
detectable this is not save.

We have grown a number of different implementations of
DIV_ROUND_CLOSEST_ULL throughout the kernel. Move the i915 one to
kernel.h so that it can be reused.
