[MIPS] SMTC: Interrupt mask backstop hack 2007-07-12T16:41:17+00:00 Kevin D.

To support legacy drivers and interrupt controller management code, SMTC has a "backstop" to track and if necessary restore the interrupt mask. This has some performance impact on interrupt service overhead. Disable it only if you know what you are doing. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
