From 1f666587dbf6bc660b23d8dd8abb6c572ce3eae5 Mon Sep 17 00:00:00 2001 From: Paul Mundt Date: Thu, 19 Oct 2006 16:20:25 +0900 Subject: sh: Fix exception_handling_table alignment. With the recent change ripping out interrupt_table, explicit padding of the table was missing, causing bad things to happen when manually inserting handlers in to the table. This problem particularly showed up in relation to do_fpu_state_restore() which was inserted quite deeply in to the table and ended up scribbling over a slab object.
