[GIT PULL] arm64: two late fixes for -final

[Will Deacon]

Hi Linus,

I thought we were done for 4.5, but then the 64k-page chaps came crawling
out of the woodwork. *sigh*

The vmemmap fix I sent for -rc7 caused a regression with 64k pages and
sparsemem and at some point during the release cycle the new hugetlb
code using contiguous ptes started failing the libhugetlbfs tests with
64k pages enabled.

So here are a couple of patches that fix the vmemmap alignment and disable
the new hugetlb page sizes whilst a proper fix is being developed.

I'm not going to pass comment on the state of things this time around.
I've learned my lesson.

Please pull.

Will
