Merge tag 'omap-for-v3.12/dra7xx' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into next/soc
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() ...
