Pull two powerpc fixes from Ben Herrenschmidt:
 "Here are a couple of fixes for 3.15.  One from Anton fixes a nasty
  regression I introduced when trying to fix a loss of irq_work whose
  consequences is that we can completely lose timer interrupts on a
  CPU... not pretty.

  The other one is a change to our PCIe reset hook to use a firmware
  call instead of direct config space accesses to trigger a fundamental
  reset on the root port.  This is necessary so that the FW gets a
  chance to disable the link down error monitoring, which would
  otherwise trip and cause subsequent fatal EEH error"

Pull renameat2 arch support from Miklos Szeredi:
 "I've collected architecture patches for the renameat2 syscall that
  maintainers acked and/or asked me to queue.

  This adds architecture support for the renameat2 syscall to m68k,
  parisc, ia64 and through asm-generic to arc, arm64, c6x, hexagon,
  metag, openrisc, score, tile, unicore32"

Pull device tree fixes from Grant Likely:
 "Drivercore bugfixes for v3.15

  This branch contains bug fixes important to get into v3.15.  There is
  a fix for modifying properties seen during early boot, a fix for an
  incorrect prototype when CONFIG_OF=n, and a couple of corrections to
  device tree memory nodes on a few platforms"

Pull MIPS fixes from Ralf Baechle:
 "MIPS fixes for various loose ends:

   - Fix workarounds for R4000 erratum.
   - Patch up DEC, Siemens-Nixdorf and Loongson hardware support.
   - Wire up renameat2 syscall.
   - Delete unused file - it was causing false warnings from maintenance
     scripts.
   - Revert a patch because it's functionality is now implemented twice
     which causes superfluous /proc/cpuinfo output.
   - Fix a microMIPS regression"

Pull parisc fixes from Helge Deller:
 "There are two patches in here:

  The first patch greatly improves latency and corrects the memory
  ordering in our light-weight atomic locking syscall.

  The second patch ratelimits printing of userspace segfaults in the
  same way as it's done on other platforms.  This fixes a possible DOS
  on parisc since it prevents the syslog to grow too fast.  For example,
  when the debian acl2 package was built on our debian buildd servers,
  this package produced lots of gigabytes in syslog in very short time
  and thus filled our harddisks, which then turned the server nearly
  completely unaccessible and unresponsive"
