[GIT PULL] arm64: fixes for -rc2

[Will Deacon]

Hi Linus,

Please pull the following arm64 fixes for 4.15-rc2. The critical one here
is a fix for fpsimd register corruption across signals which was introduced
by the SVE support code (the register files overlap), but the others are
worth having as well.

Summary in the tag.

Cheers,

Will
