Since last time:
- Fixed compile error on ppc32
- Significantly reworked mm_cpumask reset patch to restore the
  lazy PID context switch optimisation, and not over-flush the
  local CPU when flushing remotes (using IPIs).
- Moved mm_cpumask reset patch to the end of the series.

Nicholas Piggin (7):
  powerpc/64s/radix: do not flush TLB when relaxing access
  powerpc/64s/radix: do not flush TLB on spurious fault
  powerpc/64s/radix: make ptep_get_and_clear_full non-atomic for the
    full case
  powerpc/64s/radix: prefetch user address in update_mmu_cache
  powerpc/64s/radix: avoid ptesync after set_pte and
    ptep_set_access_flags
  powerpc/64s/radix: optimise pte_update
  powerpc/64s/radix: flush remote CPUs out of single-threaded mm_cpumask
