| |
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 10 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.
