From 4f896ffca2b72f4b719746e7fbb0b623252e6ac9 Mon Sep 17 00:00:00 2001 From: Paul Mundt Date: Sat, 22 Aug 2009 19:03:25 +0900 Subject: sh: unwinder: cacheline align slab cache objects. The CIE and FDE structs are big enough and accessed regularly enough in certain configurations to make cacheline alignment useful.
