[RFC PATCH v2 00/12] Reduce ifdef mess in ptrace

[Christophe Leroy]

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

This is a first try. Most of it is done, there are still some #ifdefs that
could go away.

Please comment and tell whether it is worth continuing in that direction.

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 (12):
  powerpc: move ptrace into a subdirectory.
  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
