4.9-stable review patch. If anyone has any objections, please let me know. ------------------ From: Adrian Hunter <adrian.hunter@xxxxxxxxx> commit aef4feace285f27c8ed35830a5d575bec7f3e90a upstream. Fix __kmod_path__parse() so that perf tools does not treat vdso32 and vdsox32 as kernel modules and fail to find the object.
