Subject: [PATCH 0/2] uprobes/powerpc: Replace ptrace single step helpers

The following series replaces the ptrace helpers used for single step
enable/disable for uprobes on powerpc, with uprobe specific code.

We reuse the kprobe code to enable single stepping by making it generic
and save/restore the MSR (and DBCR for BookE) across the single step.

This series applies on top of the patches posted by Oleg at :
	https://lkml.org/lkml/2012/10/28/92 


Patches have been verified on Power6 and PPC440 (BookE).
