From Tony Lindgren:
Minimal DRA7xx based SoC core support via Rajendra Nayak <rnayak@ti.com>

* tag 'omap-for-v3.12/dra7xx' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap: (849 commits)
  ARM: DRA7: Add the build support in omap2plus
  ARM: DRA7: hwmod: Reuse the soc_ops used for OMAP4/5
  ARM: DRA7: id: Add cpu detection support for DRA7xx based SoCs'
  ARM: DRA7: Kconfig: Make ARCH_NR_GPIO default to 512
  ARM: DRA7: board-generic: Add basic DT support
  ARM: DRA7: Resue the clocksource, clockevent support
  ARM: DRA7: Reuse io tables and add a new .init_early
  ARM: DRA7: Reuse all of PRCM and MPUSS SMP infra
  Linux 3.11-rc5
  btrfs: don't loop on large offsets in readdir
  Btrfs: check to see if root_list is empty before adding it to dead roots
  Btrfs: release both paths before logging dir/changed extents
  Btrfs: allow splitting of hole em's when dropping extent cache
  Btrfs: make sure the backref walker catches all refs to our extent
  Btrfs: fix backref walking when we hit a compressed extent
  Btrfs: do not offset physical if we're compressed
  Btrfs: fix extent buffer leak after backref walking
  Btrfs: fix a bug of snapshot-aware defrag to make it work on partial extents
  btrfs: fix file truncation if FALLOC_FL_KEEP_SIZE is specified
  dlm: kill the unnecessary and wrong device_close()->recalc_sigpending()
  ...
