Thanks for getting this new version out. Just a few things before it can be
applied:

  1. Can you please use "arm64:" instead of "AArch64:" in the patch
     subjects?

  2. Can you get an ack from somebody like Jason on the final patch please?

  3. Can you rebase onto the for-next/core branch at the arm64 repo:

       git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux.git

     you'll get a trivial conflict against arch/arm64/kernel/Makefile.

  4. Can you make sure that the gdb patch you linked to actually gets
     merged? There is still some discussion by the looks of it.

Cheers,

Will
