Subject: [PATCH 00/17] mm: mmu_gather rework

Rework the existing mmu_gather infrastructure.

The direct purpose of these patches was to allow preemptible mmu_gather,
but even without that I think these patches provide an improvement to the
status quo.

The first patch is a fix to the tile architecture, the subsequent 9 patches
rework the mmu_gather infrastructure. For review purpose I've split them
into generic and per-arch patches with the last of those a generic cleanup.

For the final commit I would provide a roll-up of these patches so as not
to wreck bisectability of non generic archs.

The next patch provides generic RCU page-table freeing, and the follow up
is a patch converting s390 to use this. I've also got 4 patches from
DaveM lined up (not included in this series) that uses this to implement
gup_fast() for sparc64.

Then there is one patch that extends the generic mmu_gather batching.

Finally there are 4 patches that convert various architectures over
to asm-generic/tlb.h, these are compile tested only and basically RFC.

After this only um and s390 are left -- um should be straight forward,
s390 wants a bit more, but more on that in another email.
