Subject[PATCH v2 0/5] shoot lazy tlbs
Date
This is another rebase, on top of mainline now (don't need the
asm-generic tree), and without any x86 or membarrier changes.
This makes the series far smaller and more manageable and
without the controversial bits.

Thanks,
Nick

Nicholas Piggin (5):
lazy tlb: introduce lazy mm refcount helper functions
lazy tlb: allow lazy tlb mm switching to be configurable
lazy tlb: shoot lazies, a non-refcounting lazy tlb option
powerpc: use lazy mm refcount helper functions
powerpc/64s: enable MMU_LAZY_TLB_SHOOTDOWN
