MIPS: Audit: Fix hang in entry.S.
_TIF_WORK_MASK false had _TIF_SYSCALL_AUDIT set. If a thread's _TIF_SYSCALL_AUDIT is ever set this will lead to an endless loop on the way out from a syscall. Currently this is only a theoretic bug as init/Kconfig doesn't allow AUDIT_SYSCALL to be enabled for MIPS. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
