Merge tag 'l3-fix-for-3.5' of git://git.kernel.org/pub/scm/linux/kernel/git/bp/bp into x86/urgent

A small L3 cache index disable fix from Srivatsa Bhat which unifies the
way the code checks for already disabled indices.

( Pulling it into v3.4 despite the v3.5 tag - the fix is small and we better
  keep the same code across kernel versions for such user facing interfaces. )
