From f431baa55abf8adeed0c718b51deacbc151f58f1 Mon Sep 17 00:00:00 2001 From: Atsushi Nemoto Date: Mon, 9 Oct 2006 01:24:23 +0900 Subject: [MIPS] ret_from_irq adjustment 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.
