This is a followup to patch [1] (part of [2]) where I fixed an issue that I
identified related to commit dd006da21646 ("arm64: mm: increase VA range of
identity map").

Patch #1 fixes the issue in a way that should be compatible with v4.5 and
-stable, although it may conflict trivially on hunk context.

Patch #2 is a followup that changes memstart_addr to a signed type, which is
necessary when combining patch #1 with the linear region randomization patch
that is currently queued in -next.
