Hi Linus,

Please pull these three arm64 fixes for -rc8/final. The MTE and stolen
time fixes have been doing the rounds for a little while, but review
and testing feedback was ongoing until earlier this week. The kexec fix
showed up on Monday and addresses a failure observed under Qemu.

Summary in the tag. Cheers,

Will
