[PATCH] powerpc/kprobes: fix singlestep out-of-line
We currently single-step inline if the instruction on which a kprobe is
inserted is a trap variant.
- variants (such as tdnei, used by BUG()) typically evaluate a condition
and cause a trap only if the condition is satisfied.
- kprobes uses the unconditional "trap" (0x7fe00008) and single-stepping
again on this instruction, resulting in another trap without
evaluating the condition is obviously incorrect.
