I've prepared my patch on top of Christophe's patch as it's easy
to change stepping_handler() rather than hw_breakpoint_handler().
2nd patch is the actual fix.
Christophe Leroy (1):
powerpc/hw_breakpoint: move instruction stepping out of
hw_breakpoint_handler()
Ravi Bangoria (1):
powerpc/watchpoint: Disable watchpoint hit by larx/stcx instructions
