[PATCH 0/5] Live patching for powerpc

[Michael Ellerman]

This series adds live patching support for powerpc (ppc64le only ATM).

It's unchanged since the version I posted on March 24, with the exception that
I've dropped the first patch, which was a testing-only patch.

If there's no further comments I'll put this in a topic branch in the next day
or two and Jiri & I will both merge that into next.

cheers

Michael Ellerman (5):
  ftrace: Make ftrace_location_range() global
  livepatch: Allow architectures to specify an alternate ftrace location
  powerpc/livepatch: Add livepatch header
  powerpc/livepatch: Add livepatch stack to struct thread_info
  powerpc/livepatch: Add live patching support on ppc64le
