Pulled, thanks a lot Arnaldo!

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.
