Since last posting:

- accounted for some minor omments
- improved changelogs
- updated to powerpc next which includes Gautham's idle changes.
- Fixed CONFIG_RELOCATABLE build with the new patch 1.
- Also added the last patch which simplifies the DD1 workaround,
  which is possible with HSPRG0 wakeup differences removed.

Nicholas Piggin (9):
  powerpc/64s: Remove unnecessary relocation branch from idle handler
  powerpc/64s: move remaining system reset idle code into idle_book3s.S
  powerpc/64s: stop using bit in HSPRG0 to test winkle
  powerpc/64s: use alternative feature patching
  powerpc/64s: fix POWER9 machine check handler from stop state
  powerpc/64s: idle expand core idle state bits
  powerpc/64s: idle do not hold reservation longer than required
  powerpc/64s: idle POWER8 avoid full state loss recovery where possible
