linux-toradex.git/arch/mips/kernel/smtc-asm.S, branch v3.1.2 Linux kernel for Apalis and Colibri modules [MIPS] SMTC: Don't set and restore irqregs ptr from self_ipi. 2007-06-11T17:20:53+00:00 Ralf Baechle ralf@linux-mips.org 2007-05-24T13:56:58+00:00 da9bc7263dc7e32d52dd922fe3f46eb7107c0143 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.

[MIPS] ret_from_irq adjustment 2006-10-09T22:20:46+00:00 Atsushi Nemoto anemo@mba.ocn.ne.jp 2006-10-08T16:24:23+00:00 f431baa55abf8adeed0c718b51deacbc151f58f1 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 <anemo@mba.ocn.ne.jp> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
