Thanks for your patches!

Hopefully Catalin is happy to pick this up from my branch, and neither
of us have to do anything. :)

Catalin, are you happy to pick the patches from:

  git://git.kernel.org/pub/scm/linux/kernel/git/mark/linux.git arm64/ro-swapper

... that should be based on the arm64 for-next/core branch, and has
James's R-B prior to my commit fixup notes.

I've given this some basic testing with defconfig, 48-bit/4k and
42-bit/64k (with lockdep on in both cases), and things seem fine.

Thanks,
Mark.
