      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.

      ARM: vexpress: Remove A9 PMU compatible values for non-A9 platforms · 7e16063b
      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.

From Stephen Warren <swarren@wwwdotorg.org>:

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.

      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

      Revert "lockdep: check that no locks held at freeze time" · dbf520a9
      Paul Walmsley authored 
      This reverts commit 6aa97070.

Commit 6aa97070 ("lockdep: check that no locks held at freeze time")
causes problems with NFS root filesystems.  The failures were noticed on
OMAP2 and 3 boards during kernel init:

  [ BUG: swapper/0/1 still has locks held! ]
  3.9.0-rc3-00344-ga937536b #1 Not tainted

    do_mount
    sys_mount
    do_mount_root
    mount_root
    prepare_namespace
    kernel_init_freeable
    kernel_init

Although the rootfs mounts, the system is unstable.  Here's a transcript
from a PM test:

  http://www.pwsan.com/omap/testlogs/test_v3.9-rc3/20130317194234/pm/37xxevm/37xxevm_log.txt

Here's what the test log should look like:

  http://www.pwsan.com/omap/testlogs/test_v3.8/20130218214403/pm/37xxevm/37xxevm_log.txt

Mailing list discussion is here:

  http://lkml.org/lkml/2013/3/4/221

Deal with this for v3.9 by reverting the problem commit, until folks can
figure out the right long-term course of action.
