[MIPS] SMTC: Don't set and restore irqregs ptr from self_ipi.

2007-06-11T17:20:53Z

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. Signed-off-by: Ralf Baechle

[MIPS] SMTC: Fix crash if # of TC's > # of VPE's after pt_regs irq cleanup.

[MIPS] ret_from_irq adjustment

2006-10-09T22:20:46Z

Make sure that RA on top of interrupt stack is an address of ret_from_irq, so that dump_stack etc. can trace info interrupted context. Also this patch fixes except_vec_vi_handler and __smtc_ipi_vector which seems broken. Signed-off-by: Atsushi Nemoto Signed-off-by: Ralf Baechle
