From c42d95d6c49ce9c678a9d10aeb3f526c850d66dc Mon Sep 17 00:00:00 2001 From: Thomas Koeller Date: Mon, 11 Feb 2008 23:42:12 +0100 Subject: [PATCH] [MIPS] Fix broken rm7000/rm9000 interrupt handling Properly acknowledge RM7K and RM9K interrupts. Before this, interrupts were permanently masked after their first occurrence, making them non-functional.
