Petr Mladek 2a6730c8b6 kprobes/x86: Check for invalid ftrace location in __recover_probed_insn() ... __recover_probed_insn() should always be called from an address where an instructions starts. The check for ftrace_location() might help to discover a potential inconsistency. This patch adds WARN_ON() when the inconsistency is detected. Also it adds handling of the situation when the original code can not get recovered.
