From 972da06470519b6eaef9776a586e2353f089de9c Mon Sep 17 00:00:00 2001 From: Will Deacon Date: Fri, 20 Jan 2012 12:01:09 +0100 Subject: [PATCH] ARM: 7290/1: vmlinux.lds.S: align the exception fixup table to a 4-byte boundary The exception fixup table is currently aligned to a 32-byte boundary. Whilst this won't cause any problems, the exception_table_entry structures contain only a pair of unsigned longs, so 4-byte alignment is all that is required. If the table was walked from start to end, cacheline alignment may bring some performance benefits, but since a binary search is used, the access pattern is random and will not benefit from a stricter alignment.
