git://git.kernel.org/pub/scm/linux/kernel/git/pjw/omap-pending into omap-for-v3.16/prcm
Some OMAP PRCM cleanup patches. These help prepare to convert the PRCM
code into drivers.
Basic build, boot, and PM test results are available here:
http://www.pwsan.com/omap/testlogs/prcm-cleanup-v3.16/20140515213244/
Conflicts:
arch/arm/mach-omap2/cm3xxx.c
arch/arm/mach-omap2/cm44xx.c
Also fixed up new section mismatch warnings.

SoC specific late_init call is now registered during PRM init, and will
be called automatically by PRM core. This helps to get rid of some
redundant initcalls and cpu_is_X checks from the PRM code.

Done in preparation to make PRM its own driver, as the cpu_is_XXX calls are
not available outside mach-omap2 folder.
The init functions are called only from cpu specific init chain, and thus
don't need to double check against cpu type.
The exit calls check against the data provided during init-time registration
and thus don't need cpu check either.

All OMAP IP blocks expect LE data, but CPU may operate in BE mode.
Need to use endian neutral functions to read/write h/w registers.
I.e instead of __raw_read[lw] and __raw_write[lw] functions code
need to use read[lw]_relaxed and write[lw]_relaxed functions.
If the first simply reads/writes register, the second will byteswap
it if host operates in BE mode.
Changes are trivial sed like replacement of __raw_xxx functions
with xxx_relaxed variant.

arm64 move of of_clk_init() call in a previous commit
- Default DMA ops changed to non-coherent to preserve compatibility
with 32-bit ARM DT files. The "dma-coherent" property can be used
to explicitly mark a device coherent. The Applied Micro DT file
has been updated to avoid DMA cache maintenance for the X-Gene SATA

Following arm64 commit bc3ee18a7a57 (arm64: init: Move of_clk_init to
time_init()), vexpress_osc_of_setup() is called via of_clk_init() long
before initcalls are issued. Initialising the vexpress oscillators
requires the vespress sysregs to be already initialised, so this patch
adds an explicit call to vexpress_sysreg_of_early_init() in vexpress
oscillator setup function.

Commit d57c33c5daa4 (add generic fixmap.h) added (among other
similar things) set_fixmap_io to deal with early ioremap of devices.
More recently, commit bf4b558eba92 (arm64: add early_ioremap support)
converted the arm64 earlyprintk to use set_fixmap_io. A side effect of
this conversion is that my virtual machines have stopped booting when
I pass "earlyprintk=uart8250-8bit,0x3f8" to the guest kernel.
Turns out that the new earlyprintk code doesn't care at all about
sub-page offsets, and just assumes that the earlyprintk device will
be page-aligned. Obviously, that doesn't play well with the above example.
Further investigation shows that set_fixmap_io uses __set_fixmap instead
of __set_fixmap_offset. A fix is to introduce a set_fixmap_offset_io that
uses the latter, and to remove the superflous call to fix_to_virt
(which only returns the value that set_fixmap_io has already given us).
With this applied, my VMs are back in business. Tested on a Cortex-A57
platform with kvmtool as platform emulation.

Fix for the arm64 kern_addr_valid() function to recognize
virtual addresses in the kernel logical memory map. The
function fails as written because it does not check whether
the addresses in that region are mapped at the pmd level to
2MB or 512MB pages, continues the page table walk to the
pte level, and issues a garbage value to pfn_valid().
Tested on 4K-page and 64K-page kernels.

tracing: Use rcu_dereference_sched() for trace event triggers

As trace event triggers are now part of the mainline kernel, I added
my trace event trigger tests to my test suite I run on all my kernels.
Now these tests get run under different config options, and one of
those options is CONFIG_PROVE_RCU, which checks under lockdep that
the rcu locking primitives are being used correctly. This triggered
the following splat:

rcu_dereference_sched().

Pull ACPI and power management fixes from Rafael Wysocki:
"A bunch of regression fixes this time. They fix two regressions in
the PNP subsystem, one in the ACPI processor driver and one in the
ACPI EC driver, four cpufreq driver regressions and an unrelated bug
in one of the drivers. The regressions are recent or introduced in
3.14.
Specifics:
- There are two bugs in the ACPI PNP core that cause errors to be
returned if optional ACPI methods are not present. After an ACPI
core change made in 3.14 one of those errors leads to serial port
suspend failures on some systems. Fix from Rafael J Wysocki.
- A recently added PNP quirk related to Intel chipsets intorduced a
build error in unusual configurations (PNP without PCI). Fix from
Bjorn Helgaas.
- An ACPI EC workaround related to system suspend on Samsung machines
added in 3.14 introduced a race causing some valid EC events to be
discarded. Fix from Kieran Clancy.
- The acpi-cpufreq driver fails to load on some systems after a 3.14
commit related to APIC ID parsing that overlooked one corner case.
Fix from Lan Tianyu.
- Fix for a recently introduced build problem in the ppc-corenet
cpufreq driver from Tim Gardner.
- A recent cpufreq core change to ensure serialization of frequency
transitions for drivers with a ->target_index() callback overlooked
the fact that some of those drivers had been doing operations
introduced by it into the core already by themselves. That
resulted in a mess in which the core and the drivers try to do the
same thing and block each other which leads to deadlocks. Fixes
for the powernow-k7, powernow-k6, and longhaul cpufreq drivers from
Srivatsa S Bhat.

Commit 2ee57d58735 ("dm cache: add passthrough mode") inadvertently
removed the deferred set reference that was taken in cache_map()'s
writethrough mode support. Restore taking this reference.
This issue was found with code inspection.

There are only a couple of architectures that override _STK_LIM_MAX to
a non-infinity value. This changes the stack allocation semantics in
subtle ways. For example, GNU make changes its stack allocation to the
hard maximum defined by _STK_LIM_MAX. As a results, threads executed
by processes running under make are allocated a stack size of
_STK_LIM_MAX rather than a sensible default value. This causes various
thread stress tests to fail when they can't muster more than about 50
threads.
The attached change implements the default behavior used by the
majority of architectures.

Both of these bug fixes should be queued up for stable as well"
