[PATCH v2 0/5] Extend and consolidate mmu_gather into new file

From: Will Deacon
Date: Tue Sep 04 2018 - 07:45:43 EST


Hi all,

This series builds on the core changes I previously posted here:

rfc: http://lists.infradead.org/pipermail/linux-arm-kernel/2018-August/597821.html
v1: http://lists.infradead.org/pipermail/linux-arm-kernel/2018-August/598919.html

The main changes are:

* Move the mmu_gather bits out of memory.c and into their own file
(looped in the mm people for this)

* Add a MAINTAINERS entry for the new file, and all tlb.h headers.
If any mm developers would like to be included here as well, please
just ask.

I'd like to queue these patches on their own branch in the arm64 git so
that others can develop on top of them for the next merge window. Peter
and Nick have both expressed an interest in that, and I already have a
bunch of arm64 optimisations on top which I posted previously.

Cheers,

Will
