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

Hi Linus,

Please pull these fixes for arm64. The main things are getting kgdb up
and running with upstream GDB after a protocol change was reverted and
fixing our spin_unlock_wait/spin_is_locked implementations after doing
some similar work with PeterZ on the qspinlock code last week. Whilst we
haven't seen any failures in practice, it's still worth getting this
fixed.

Thanks,

Will
