      Turn off -Wmaybe-uninitialized when building with -Os · e74fc973
      Arnd Bergmann authored 
      gcc-4.7 and higher add a lot of false positive warnings about
potential uses of uninitialized warnings, but only when optimizing
for size (-Os). This is the default when building allyesconfig,
which turns on CONFIG_CC_OPTIMIZE_FOR_SIZE.

In order to avoid getting a lot of patches that initialize such
variables and accidentally hide real errors along the way, let's
just turn off this warning on the respective gcc versions
when building with size optimizations. The -Wmaybe-uninitialized
option was introduced in the same gcc version (4.7) that is now
causing the false positives, so there is no effect on older compilers.

A side effect is that when building with CONFIG_CC_OPTIMIZE_FOR_SIZE,
we might now see /fewer/ warnings about possibly uninitialized
warnings than with -O2, but that is still much better than seeing
warnings known to be bogus.

      The linux/cpu.h header is no longer implictly included in this
file, so we need to an #include statement to avoid this build
warning:

      ARM: tegra: call cpu_do_idle from C code · 2058842e
      Arnd Bergmann authored 
      When building a kernel for multiple CPU architecture levels,
cpu_do_idle() is a macro for an indirect function call, which
cannot be called from assembly code as Tegra does.

Adding a trivial C wrapper for this function lets us build
a tegra kernel with ARMv6 support enabled.

      ARM: OMAP2+: add dependencies on ARCH_MULTI_V6/V7 · 4b0ed696
      Arnd Bergmann authored 
      CONFIG_ARCH_OMAP2PLUS depends on (ARCH_MULTI_V6 || ARCH_MULTI_V7) as of
a0694861 "ARM: OMAP2+: Enable ARCH_MULTIPLATFORM support", but the
individual OMAP2/3/4/5 and AM33XX platforms can all be selected independent
of what we are building for, which is a bug and prevents us from easily
building e.g. an ARMv7-only defconfig.

This makes ARCH_OMAP2 depend on ARCH_MULTI_V6 and the others depend on
ARCH_MULTI_V7, to ensure we really only build the platforms for the
CPUs we have enabled in the global multiplatform configuration step.

      ARM: msm: Fix uncompess.h tx underrun check · 73a8c28f
      Stephen Boyd authored 
      Bit 3 of the SR register is set if there is a tx underrun. If
this bit isn't set, we should loop on the tx ready bit until we
can transmit again. Otherwise we should skip the loop and
transmit immediately. The code is doing the opposite though,
checking for an underrun and then looping on the tx ready bit
causing us to never loop on the tx read bit when the tx buffer
may not be ready.

This doesn't seem to affect my 8960 device too often, but in some
cases I see a lost character or two from the decompressor prints.
This also matches what we do in the assembly in debug-macro.S.

      Pawel Moll authored 
      The ARM perf core code used to rely on the pmu node being
compatible with "arm,cortex-a9-pmu", even when the PMUs
of the different Cortex-A processors are not really
compatible... This is no longer required and actually
became harmful, so remove all the offending values
from Versatile Express DTS files.

ARM: tegra: minor fixes

This branch contains a variety of small build and run-time fixes that
weren't important enough for 3.9.

* Enable CPU errata WARs in secondary reset handler as a preparation
  for multi-platform support, and a related fix.
* Don't touch DBLGAR in reset/resume handlers, so enable the code to
  run on A15 cores.
* Minor build fixes.
* A fix to the Tegra clock driver.
* Some error-handling fixes.

This branch is based on the previous fixes-for-mmc pull request.

* tag 'tegra-for-3.10-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/swarren/linux-tegra:
  ARM: tegra: powergate: Don't error out if new state == old state

      Merge tag 'v3.9-rc1_cns3xxx_fixes' of git://git.infradead.org/users/cbou/linux-cns3xxx into next/fixes-non-critical

From Anton Vorontsov <anton@enomsg.org>:

This tag includes Mac Lin's work to revive CNS3xxx booting:

 "Since commit 0536bdf3 (ARM: move iotable mappings within the vmalloc
 region), [...] the pre-defined iotable mappings is not in the vmalloc
 region. [...] move the iotable mappings into the vmalloc region, and
 merge the MPCore private memory region (containing the SCU, the GIC and
 the TWD) as a single region."

Plus there is a small cosmetic fix, also from Mac Lin.

* tag 'v3.9-rc1_cns3xxx_fixes' of git://git.infradead.org/users/cbou/linux-cns3xxx:
  ARM: cns3xxx: remove unused virtual address and iotable defines
  ARM: cns3xxx: fix mapping of private memory region
