Subject: [PATCH v4 00/13] Reduce ifdef mess in ptrace

The purpose of this series is to reduce the amount of #ifdefs
in ptrace.c

Link: https://github.com/linuxppc/issues/issues/128

Tentatively build checked on kisskb allthough kisskb seems overloaded and failing to complete the tests.
See http://kisskb.ellerman.id.au/kisskb/branch/chleroy/head/ff12a199b21e80584096a72665023d212499accd/

v4:
- Fixed a few header files inclusion, see details in relevant patchs (no marking on unchanged patches).

v3:
- Droped part of #ifdef removals iaw mpe's comments
- Removed unneccesary includes

v2:
- Fixed several build failures. Now builts cleanly on kisskb, see http://kisskb.ellerman.id.au/kisskb/head/840e53cf913d6096dd60181a085f102c85d6e526/
- Droped last patch which is not related to ptrace and can be applies independently.

Christophe Leroy (13):
  powerpc: move ptrace into a subdirectory.
  powerpc/ptrace: remove unused header includes
  powerpc/ptrace: drop unnecessary #ifdefs CONFIG_PPC64
  powerpc/ptrace: drop PARAMETER_SAVE_AREA_OFFSET
  powerpc/ptrace: split out VSX related functions.
  powerpc/ptrace: split out ALTIVEC related functions.
  powerpc/ptrace: split out SPE related functions.
  powerpc/ptrace: split out TRANSACTIONAL_MEM related functions.
  powerpc/ptrace: move register viewing functions out of ptrace.c
  powerpc/ptrace: split out ADV_DEBUG_REGS related functions.
  powerpc/ptrace: create ptrace_get_debugreg()
  powerpc/ptrace: create ppc_gethwdinfo()
  powerpc/ptrace: move ptrace_triggered() into hw_breakpoint.c
