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).
