Most supported systems currently hardwire cpu_has_dsp to 0, so we also
can disable support for cpu_has_dsp2 resulting in a slightly smaller
kernel.

[ralf@linux-mips.org: This patch really only detects the ASE and passes its
existence on to userland via /proc/cpuinfo. The DSP ASE Rev 2. adds new
resources but no resources that would need management by the kernel.]

On a dual issue processor GCC generates code that saves a couple of
clock cycles per loop if we rearrange things slightly. Checking for
p != end saves a SLTU per loop, moving the increment to the middle can
let it dual issue on multi-issue processors.

Add hardware performance counter support to kernel "perf" code for
BMIPS5000. The BMIPS5000 performance counters are similar to MIPS
MTI cores, so the changes were mostly made in perf_event_mipsxx.c
which is typically for MTI cores.

Split the Kconfig option CONFIG_MIPS_MT_SMP into CONFIG_MIPS_MT_SMP
and CONFIG_MIPS_PERF_SHARED_TC_COUNTERS so some of the code used
for performance counters that are shared between threads can be used
for MIPS cores that are not MT_SMP.

The #ifdef for CONFIG_HW_PERF_EVENTS is not needed because the
Makefile will only compile the module if this config option is set.
This means that the code under #else would never be compiled. This
may have been done to leave the original broken code around for
reference, but the FIXME comment above the code already shows the
broken code.

The PCI (Program Counter Interrupt) bit in the "cause" register
is mandatory for MIPS32R2 cores, but has also been added to some R1
cores (BMIPS5000). This change adds a cpu feature bit to make it
easier to check for and use this feature.

Change the indicator from 0xffffffff in the "event_id" member to
zero in the "cntr_mask" member. This removes the need to initialize
entries that are unsupported. This also solves a problem where the
number of entries in the table was increased based on a globel enum
used for all platforms, but the new unsupported entries were not added
for mips. This was leaving new table entries of all zeros that we not
marked UNSUPPORTED.

We can save an instruction in the TLB Refill path for kernel mappings
by aligning swapper_pg_dir on a 64K boundary. The address of
swapper_pg_dir can be generated with a single LUI instead of
LUI/{D}ADDUI.
The alignment of __init_end is bumped up to 64K so there are no holes
between it and swapper_pg_dir, which is placed at the very beginning
of .bss.
The alignment of invalid_pmd_table and invalid_pte_table can be
relaxed to PAGE_SIZE. We do this by using __page_aligned_bss, which
has the added benefit of eliminating alignment holes in .bss.

I've maintained this patch, originally from Thiemo Seufer in 2004, for a
really long time, but I think it's time for it to get a look at for
possible inclusion. I have had no problems with it across various SGI
systems over the years.
To quote the post here:
http://www.linux-mips.org/archives/linux-mips/2004-12/msg00000.html
"the atomic functions use so far memory references for the inline
assembler to access the semaphore. This can lead to additional
instructions in the ll/sc loop, because newer compilers don't
expand the memory reference any more but leave it to the assembler.
The appended patch uses registers instead, and makes the ll/sc
arguments more explicit. In some cases it will lead also to better
register scheduling because the register isn't bound to an output
any more."

Pull i2c-embedded changes from Wolfram Sang:
"The changes for i2c-embedded include:
- massive rework of the omap driver
- massive rework of the at91 driver. In fact, the old driver gets
removed; I am okay with this approach since the old driver was
depending on BROKEN and its limitations made it practically
unusable, so people used bitbanging instead. But even if there are
users, there is no platform_data or module parameter which would
need to be converted. It is just another driver doing I2C
transfers, just way better. Modifications of arch/arm/at91 related
files have proper acks from the maintainer.
- new driver for R-Car I2C
- devicetree and generic_clock conversions and fixes
- usual driver fixes and changes.
The rework patches have come a long way and lots of people have been
involved in creating/testing them. Most patches have been in
linux-next at least since 3.6-rc5. A few have been added in the last
week, I have to admit.
An unexpected (but welcome :)) peak in private life is the cause for
that. The "late" patches shouldn't cause any merge conflicts and I
will have a special eye on them during the stabilization phase. This
is an exception and I want to have the patches in place properly in
time again for the next kernels."

Missing error types, attributes, and report fields. Pad out
to 64-bytes.
Make string reporting cleaner and easier to extend in the future using
"const char *" arrays that index by either bit position, or absolute
field value.
Report the raw 64-byte error report as a sequence of u64s before the
annotated version.
Only report fields which are valid, given the context and the
attribute bits which are set.
For shutdown requests, use the local copy of the error report not the
one we just freed up back to the queue. Also, use orderly_poweroff()
just like the Domain Services shutdown request code does.
If the real-address reported is "-1" (unknown) try to disassemble the
instruction to report the effective address of the access. Only do
this in privileged mode.

Pull pwm changes from Thierry Reding:
"All legacy PWM providers have now been moved to the PWM subsystem.
The plan for 3.8 is to adapt all board files to provide a lookup table
for PWM devices in order to get rid of the global namespace.
Subsequently, users of the legacy pwm_request() and pwm_free()
functions can be migrated to the new pwm_get() and pwm_put()
functions. Once this has been completed, the legacy API and the
compatibility code in the core can be removed.
In addition to the above, these changes also add support for
configuring the polarity of a PWM signal (currently only supported on
ECAP and EHRPWM) and include a much needed rework of the i.MX driver.
Managed functions to obtain and release a PWM device (devm_pwm_get()
and devm_pwm_put()) have been added and the pwm-backlight driver has
been updated to use them. If the PWM subsystem hasn't been enabled,
dummy functions are provided that allow the subsystem to safely
compile out.
Some common checks on input parameters have been moved to the core and
removed from the drivers. Finally, a small fix corrects the
description of the PWM specifier's second cell in the device tree
representation."

Upgrade nomadik pinctrl driver to enable selection of other
alternate-C[1-4] functions on some specific ux500 SoC pins.
Handling of those functions is done thanks to PRCM GPIOCR
registers. This was previously managed in PRCMU driver and
it was not really convenient. Idea is to provide a common
way to control all alternate functions.
Note that this improvement does not support the old-fashioned way
used to control nomadik pins, namely the "nmk_config_pin()" function
and its derivatives.

Omapdss driver changes for the 3.7 merge window.
Notable changes:
* Basic writeback support for DISPC level. Writeback is not yet usable, though,
as we need higher level code to actually expose the writeback feature to
userspace.
* Rewriting the omapdss output drivers. We're trying to remove the hard links
between the omapdss and the panels, and this rewrite work moves us closer to
that goal.
* Cleanup and restructuring patches that have been made while working on device
tree support for omapdss. Device tree support is still some way ahead, but
these patches are good cleanups in themselves.
* Basic OMAP5 DSS support for DPI and DSI outputs.
* Workaround for the problem that GFX overlay's fifo is too small for high
resolution scenarios, causing underflows.
* Cleanups that remove dependencies to omap platform code.

git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into fixes
From Tony Lindgren:
This branch contains regression fixes for omap4/5 ASoC
audio that were caused by the fact that u-boot stopped
muxing non essential pins.
As omap audio and dmaengine development happens on
these platforms, let's make sure they are usable.
Of course this should have been fixed earlier and
not during the -rc cycle.

git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into fixes
From Tony Lindgren:
These were agreed to be merged via arm soc tree as Rafael
is on vacation.
From Kevin Hilman <khilman@deeprootsystems.com>:
This series a couple bug fixes and a couple fixes that make this
driver support recently added OMAP-based SoCs.
The 'get_cpu_device' patch is needed due to a change in the OMAP
OMAP PM core code which enforces use of get_cpu_device() instead of
a deprecated OMAP-specific API.
The usage of plat/*.h headers breaks single zImage, so platforms are
cleaning up and/or removing plat/*.h so the driver needs to be fixed
accordingly.
This series is based on the merge of Rafael's pm-for-3.7-rc1 tag into
Linus' master branch: commit 16642a2e7be23bbda013fc32d8f6c68982eab603.

From Tony Lindgren:
This branch contains one counter locking fix and an
alignment fix. Other fixes are warning fixes, fixes
for return value checks.
I've also included removal of some extra semicolons,
dropping of some duplicate includes, and an a change
for wl12xx enumeration that are not strictly fixes
but would be good to get out of the way for -rc1.

The it8152 PCI host used on the pxa/cm_x2xx machines
uses the old-style I/O window registration. This should
eventually get converted to pci_ioremap_io() but for
now, let's cast the IT8152_IO_BASE constant to an integer
type to get rid of the warnings.
Without this patch, building cm_x2xx_defconfig results in:

On NOMMU ARM, the __addr_ok() and __range_ok() macros do not evaluate
their arguments, which may lead to harmless build warnings in some
code where the variables are not used otherwise. Adding a cast to void
gets rid of the warning and does not make any semantic changes.
Without this patch, building at91x40_defconfig results in:

The flat_get_addr_from_rp() macro does not use the 'persistent' argument
on ARM, causing a harmless compiler warning. A cast to void removes
that warning.

Sometimes we want the kernel build process to only print messages
on errors, e.g. in automated build testing. This uses the "kecho"
macro that the build system provides to hide a few informational
messages. Nothing changes for a regular "make" or "make V=1".
Without this patch, building any ARM kernel results in:

The Linaro cross toolchain and probably others nowadays default to
building in THUMB2 mode. When building a kernel for a CPU that does
not support THUMB2, the compiler complains about incorrect flags.
We can work around this by setting -marm for all non-T2 builds.
-marm was passed unconditionally for C files previously, but nothing was
passed to the gcc frontend when processing .S files, resulting in a
warning. The assembler never defaults to ARM unless -Wa,-mthumb is
supplied explicitly, so the files were still assembled correctly.
This patch makes sure that -marm is passed for .S files too, and also
avoids the redundant gcc -marm -mthumb in Thumb kernels.
Without this patch, building assabet_defconfig results in:
usr/initramfs_data.S:1:0: warning: target CPU does not support THUMB instructions [enabled by default]
arch/arm/nwfpe/entry.S:1:0: warning: target CPU does not support THUMB instructions [enabled by default]
firmware/cis/PCMLM28.cis.gen.S:1:0: warning: target CPU does not support THUMB instructions [enabled by default]
(and many more)
