 "Some further ARM fixes:
   - another build fix for the kprobes test code
   - a fix for no kuser helpers for the set_tls code, which oopsed on
     noMMU hardware
   - a fix for alignment handler with neon opcodes being misinterpreted
   - turning off the hardware access support, which is not implemented
   - a build fix for the v7 coherency exiting code, which can be built
     in non-v7 environments (but still only executed on v7 CPUs)"

  ARM: 8179/1: kprobes-test: Fix compile error "bad immediate value for offset"
  ARM: 8178/1: fix set_tls for !CONFIG_KUSER_HELPERS

  ARM: 8165/1: alignment: don't break misaligned NEON load/store
  ARM: 8164/1: mm: clear SCTLR.HA instead of setting it for LPAE

When compiling kprobes-test-arm.c the following error has been observed

/tmp/ccoT403o.s:21439: Error: bad immediate value for offset (4168)

This is caused by the compiler spilling it's literal pool too far away
from the site which is trying to reference it with a PC relative load.
This arises because the compiler is underestimating the size of the
inline assembler code present, which apparently it approximates as 4
bytes per line or instruction.

We fix this problem by moving the operations which generate more than
4 bytes out of the text section. Specifically, moving the .ascii
directives to the .rodata section.

Joachim Eastwood reports that commit fbfb872f5f41 "ARM: 8148/1: flush
TLS and thumbee register state during exec" causes a boot-time crash
on a Cortex-M4 nommu system:

The problem is that set_tls is attempting to clear the TLS location in
the kernel-user helper page, which isn't set up on V7M.

Fix this by guarding the write to the kuser helper page with
a CONFIG_KUSER_HELPERS ifdef.

This fixes build breakage of platsmp.c if ARMv6 was chosen for compile
time options (e.g. by building allmodconfig):

$ make allmodconfig
$ make
  CC      arch/arm/mach-exynos/platsmp.o
/tmp/ccdQM0Eg.s: Assembler messages:
/tmp/ccdQM0Eg.s:432: Error: selected processor does not support ARM mode `isb '
/tmp/ccdQM0Eg.s:437: Error: selected processor does not support ARM mode `isb '
/tmp/ccdQM0Eg.s:438: Error: selected processor does not support ARM mode `dsb '
make[1]: *** [arch/arm/mach-exynos/platsmp.o] Error 1

The error was introduced in commit "ARM: EXYNOS: Move code from
hotplug.c to platsmp.c".  Previously code using
v7_exit_coherency_flush() macro was built with '-march=armv7-a' flag but
this flag dissapeared during the movement.

Fix this by annotating the v7_exit_coherency_flush() asm code with
armv7-a architecture.

Pull ARM SoC fixes from Olof Johansson:
 "Here's our last set of fixes for 3.17.  Most of these are for TI
  platforms, fixing some noisy Kconfig issues, runtime clock and power
  issues on several platforms and NAND timings on DRA7.

  There are also a couple of bug fixes for i.MX, one for QCOM and a
 small fix to avoid section mismatch noise on PXA.

  Diffstat looks large, partially due to some tables being updated and
  thus touching many lines.  The qcom gsbi change also restructures
  clock management a bit and thus touches a bunch of lines.

  All in all, a bit more changes than we'd like at this point, but
  nothing stands out as risky either so it seems like the right thing to
  send it up now instead of holding it to the merge window"

The alignment fixup incorrectly decodes faulting ARM VLDn/VSTn
instructions (where the optional alignment hint is given but incorrect)
as LDR/STR, leading to register corruption. Detect these and correctly
treat them as unhandled, so that userspace gets the fault it expects.

SCTLR.HA (hardware access flag) is deprecated and not actually
implemented by any CPUs. Furthermore, it can confuse cr_alignment checks
where the whole value of SCTLR is compared against the value sitting in
the hardware, since the bit is actually RAZ/WI and will not match the
saved cr_alignment value.

Regression fix for early omap3 revisions for wake-up events that
too some time to narrow down. Although a bit intrusive, this would
be good to get into the -rc cycle as there are quite a few boards
out there with omap3 es2.1 and es3.0, and we have those in at least
three boot test systems too that show errors without this patch.
