Subject: [GIT PULL] arm64: fixes for -rc4

Hi Linus,

Please pull the following arm64 fixes for 4.15-rc4.

I've included the usual summary in the tag, but there are some significant
fixes in here for FP state corruption, hardware access/dirty PTE corruption
and an erratum workaround for the Falkor CPU. I'm hoping that things
finally settle down now, but never say never...

Cheers,

Will
