uprobes/x86: Emulate nop's using ops->emulate() Finally we can kill the ugly (and very limited) code in __skip_sstep(). Just change branch_setup_xol_ops() to treat "nop" as jmp to the next insn. Thanks to lib/insn.c, it is clever enough. OPCODE1() == 0x90 includes "(rep;)+ nop;" at least, and (afaics) much more.
