 Does anyone have the appetite to move this helper function to
 include/linux/securebits.h along with issecure() to make it more widely
 available? 
If it's going to have wider scope, then it probably needs to be
renamed to be unambiguous in any context.  root_implies_privilege
or uid0_is_privileged maybe?   Maybe root_privileged() is ok...
