- upstream kpatch-build now supports this

These patches add simplifications and improvements for some issues Peter
found six months ago, as part of his non-writable text code (W^X)
cleanups.

Highlights:

- Remove the livepatch arch-specific .klp.arch sections, which were used
  to do paravirt patching and alternatives patching for livepatch
  replacement code.

- Add support for jump labels in patched code (only for static keys
  which live in vmlinux).

- Remove the last module_disable_ro() usage.

For more background, see this thread:

  https://lkml.kernel.org/r/20191021135312.jbbxsuipxldocdjk@treble

This has been tested with kpatch-build integration tests and klp-convert
selftests.

So I think this should best go through livepatching.git for 5.8. Unless 
anyone has a better idea or objects heavily, I'll queue it tomorrow.

Thanks,
