Subject: [PATCH] SELinux: change isec semaphore to a mutex
This patch converts the remaining isec->sem into a mutex. Very similar
locking is provided as before only in the faster smaller mutex rather than a
semaphore. An out_unlock path is introduced rather than the conditional
unlocking found in the original code.
