Hi Linus,

Please pull these three arm64 fixes for -rc4. One of them is just a
trivial documentation fix, whereas the other two address a warning in
the kexec code and a crash in ftrace on systems implementing BTI. The
latter patch has a couple of ugly ifdefs which Mark plans to clean up
separately, but as-is the patch is straightforward for backporting to
stable kernels.

Cheers,

Will
