Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jmorris/linux-security 

Pull SELinux regression fixes from James Morris.

Andrew Morton has a box that hit that open perms problem.

I also renamed the "epollwakeup" selinux name for the new capability to
be "block_suspend", to match the rename done by commit d9914cf661
("PM: Rename CAP_EPOLLWAKEUP to CAP_BLOCK_SUSPEND").

* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jmorris/linux-security:
  SELinux: do not check open perms if they are not known to policy
  SELinux: include definition of new capabilities
