[PATCH v3 0/6] powerpc: merge _switch in 32/64

[Nicholas Piggin]

Since v2:
- Add PPC_CREATE_STACK_FRAME() to abstract prologue differences.
- Build fix.
- Makefile tidy [Christophe]
- Fix a missing SOB.

Since v1:
- Don't re-order 32-bit prologue.
- Improve Kconfig conditional includes.
- Break out code changes into their own patches before merging,
  so merge patch leaves generated code unchanged.
- Change prom_entry.S to prom_entry_64.S.


Nicholas Piggin (6):
  powerpc/64s: move stack SLB pinning out of line from _switch

  powerpc/32: Rearrange _switch to prepare for 32/64 merge
  powerpc: merge 32-bit and 64-bit _switch implementation
