[PATCH v2 0/4] uprobes/powerpc: Replace ptrace helpers for single stepping
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). Changes since V1: * Don't disable external interrupts. (Sebastian) * Introduced routines for saving/restoring the context for sstep. * Restore the context in arch_uprobe_abort_xol() (Oleg) --- Suzuki K.
