This patch against 2.6.0-test3-mm3 adds calls to the
security_task_to_inode hook to the pid*_revalidate functions to ensure
that the inode security field is also updated appropriately for
/proc/pid inodes. This corresponds with the uid/gid update performed by
the proc-pid-setuid-ownership-fix.patch that is already in -mm3.
