From d66433ffdced6537ab7e6c423a8f14091c51e3e2 Mon Sep 17 00:00:00 2001 From: "Edgar E. Iglesias" Date: Sat, 18 Jan 2014 04:07:48 +0000 Subject: cris: Abort when a v10 takes interrupts while in a delayslot This is an internal error as the CRISv10 should mask interrupts while executing delay slots. Bail out sooner rather than later. Signed-off-by: Edgar E.
