Hi Linus,

Please pull the arm64 changes below. It's mostly fixes apart from the
kprobe blacklist checking which was deferred because of conflicting with
a fix merged after I pinned the arm64 for-next/core branch (f2b3d8566d81
"arm64: kprobe: Always blacklist the KVM world-switch code").


The following changes since commit 9e98c678c2d6ae3a17cb2de55d17f69dddaa231b:
