[RFC PATCH v1 00/13] Reduce ifdef mess in ptrace

From: Christophe Leroy
Date: Tue Jun 25 2019 - 06:58:11 EST


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.

Christophe Leroy (13):
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
powerpc/hw_breakpoint: move instruction stepping out of
hw_breakpoint_handler()
