MAINTAINERS: Add entry for MMU GATHER AND TLB INVALIDATION
We recently had to debug a TLB invalidation problem on the munmap()
path, which was made more difficult than necessary because:
(a) The MMU gather code had changed without people realising
(b) Many people subtly misunderstood the operation of the MMU gather
code and its interactions with RCU and arch-specific TLB invalidation
(c) Untangling the intended behaviour involved educated guesswork and
plenty of discussion
Hopefully, we can avoid getting into this mess again by designating a
cross-arch group of people to look after this code. It is not intended
that they will have a separate tree, but they at least provide a point
of contact for anybody working in this area and can co-ordinate any
proposed future changes to the internal API.
