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
