[GIT PULL] arm64 fixes for 4.18-rc5

[will.deacon@arm.com (Will Deacon)]

Hi Linus,

Catalin's out enjoying the sunshine, so I'm sending the fixes for a couple
of weeks (although there hopefully won't be any more!). Summary is in the
tag, but we've got a revert of a previous fix because it broke the build
with some distro toolchains and a preemption fix when detemining whether
or not the SIMD unit is in use.

Please pull. Thanks,

Will
