The various variations of kptr_restrict now work fine AFAICS - will send the fixes to Linus today. One (very) small issue i noticed, if the user only samples user-space events then i still get the warning: aldebaran:~> perf record -e cycles:upp sleep 1 WARNING: Kernel address maps (/proc/{kallsyms,modules}) are restricted, although perf does not record any kernel samples so kptr_restrict is irrelevant in this case.
