If it were me I would start with a simpler patch that doesn't implement it
at all on BookE,
From: Roland McGrath
Reworked by: Benjamin Herrenschmidt
This adds block-step support on powerpc, including a PTRACE_SINGLEBLOCK
request for ptrace.
The BookE implementation is tweaked to fire a single step after a
block step in order to mimmic the server behaviour.
