* gdbarch.sh (displaced_step_hw_singlestep): New callback.
* gdbarch.c, gdbarch.h: Regenerate.
* arch-utils.c (default_displaced_step_hw_singlestep): New function.
* arch-utils.h (default_displaced_step_hw_singlestep): Add prototype.
* ppc-linux-tdep.c (ppc_displaced_step_hw_singlestep): New function.
(rs6000_gdbarch_init): Install it.
* infrun.c (displaced_step_fixup): Use new callback to determine
whether to "step" or "continue" displaced copy.
(resume): Likewise. Do not call maybe_software_singlestep
for displaced stepping.
(maybe_software_singlestep): Do not handle displaced stepping.
