[MIPS] SMTC: Don't set and restore irqregs ptr from self_ipi. This did corrupt register s0 which the caller of self_ipi expects to be unchanged. This is a kernel bug which will only be triggered with the compilers which compile __smtc_ipi_replay to use s0 across the invocation of self_ipi. Gcc 4.1.2 does this, for example.
