[MIPS] Dyntick support for SMTC:
The kernel currently only supports broadcasting of the timer interrupt from a single timer, not multicasting into two multicast groups of processors. So the implemented mechanism for SMTC works by broadcasting the cp0 compare interrupt on VPE 0 and ignoring it on any additional VPEs. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
