Merge branch 'merge' of git://git.kernel.org/pub/scm/linux/kernel/git/benh/powerpc 

Pull powerpc fixes from Ben Herrenschmidt:
 "Here are a few more powerpc fixes for 3.16

  There's a small series of 3 patches that fix saving/restoring MMUCR2
  when using KVM without which perf goes completely bonkers in the host
  system.  Another perf fix from Anton that's been rotting away in
  patchwork due to my poor eyesight, a couple of compile fixes, a little
  addition to the WSP removal by Michael (removing a bit more dead
  stuff) and a fix for an embarassing regression with our soft irq
  masking"

* 'merge' of git://git.kernel.org/pub/scm/linux/kernel/git/benh/powerpc:
  powerpc/perf: Never program book3s PMCs with values >= 0x80000000
  powerpc: Disable RELOCATABLE for COMPILE_TEST with PPC64
  powerpc/perf: Clear MMCR2 when enabling PMU
  powerpc/perf: Add PPMU_ARCH_207S define
  powerpc/kvm: Remove redundant save of SIER AND MMCR2
  powerpc/powernv: Check for IRQHAPPENED before sleeping
  powerpc: Clean up MMU_FTRS_A2 and MMU_FTR_TYPE_3E
  powerpc/cell: Fix compilation with CONFIG_COREDUMP=n
