Subject: [GIT PULL] arm64 fixes for -rc5

Hi Linus,

Please pull these arm64 fixes for -rc5. It's all pretty minor but the
main fix is sorting out how we deal with return values from 32-bit system
calls as audit expects error codes to be sign-extended to 64 bits

Brief summary in the tag.

Cheers,

Will
