[PATCH] MAINTAINERS: add memory advice section

[Lorenzo Stoakes]

The madvise code straddles both VMA and page table manipulation. As a
result, separate it out into its own section and add maintainers/reviewers
as appropriate.

We additionally include the mman-common.h file as this contains the shared
madvise flags and it is important we maintain this alongside madvise.c.

For me "MADVISE" would be the most obvious but I don't really mind either way.

Is it intentional that this one, unlike "MEMORY MAPPING", has no
explicit "L: linux-mm@kvack.org" and relies on the inheritance from
the overall "MEMORY MANAGEMENT" entry for that?

"madvise" is what people will search for.  Perhaps

	MEMORY MAPPING - MADVISE (MEMORY ADVICE)

Yeah, this seems better, also as Jann pointed out I missed off the L line
by mistake, can you apply the following fix-patch? Thanks!

No, was a mistake, have asked Andrew to fix in a fixpatch! Good

I mean we give advice on memory right? ;)

I think Andrew's suggestion of madvise (memory advice) should cover
everything off. I adjust felt icky at the grammar of saying madvise here
but that idea fixes that.
