powerpc/kprobes: Do not disable interrupts for optprobes and kprobes_on_ftrace
Per Documentation/kprobes.txt, we don't necessarily need to disable interrupts before invoking the kprobe handlers. Masami submitted similar changes for x86 via commit a19b2e3d ("kprobes/x86: Remove IRQ disabling from ftrace-based/optimized kprobes"). Do the same for powerpc. Signed-off-by: Naveen N.
