Merge remote-tracking branch 'linus/master' into staging/for_v3.8
* linus/master: (1428 commits) futex: avoid wake_futex() for a PI futex_q watchdog: using u64 in get_sample_period() writeback: put unused inodes to LRU after writeback completion mm: vmscan: check for fatal signals iff the process was throttled Revert "mm: remove __GFP_NO_KSWAPD" proc: check vma->vm_file before dereferencing UAPI: strip the _UAPI prefix from header guards during header installation include/linux/bug.h: fix sparse warning related to BUILD_BUG_ON_INVALID Linux 3.7-rc7 powerpc/eeh: Do not invalidate PE properly ALSA: hda - Fix build without CONFIG_PM of/address: sparc: Declare of_iomap as an extern function for sparc again PM / QoS: fix wrong error-checking condition bnx2x: remove redundant warning log vxlan: fix command usage in its doc 8139cp: revert "set ring address before enabling receiver" MPI: Fix compilation on MIPS with GCC 4.4 and newer MIPS: Fix crash that occurs when function tracing is enabled MIPS: Merge overlapping bootmem ranges jbd: Fix lock ordering bug in journal_unmap_buffer() ...
