[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.
