From a81cbd2da48eacc860acf4f40ea05db790f4c7c3 Mon Sep 17 00:00:00 2001 From: Oskar Schirmer Date: Wed, 4 Mar 2009 16:21:30 +0100 Subject: [PATCH] xtensa: enforce slab alignment to maximum register width XCHAL_DATA_WIDTH is the maximum register width, slab caches should be aligned to this. Theoretical fix as all variants have had an XCHAL_DATA_WIDTH of 4 (wordsize) for now. But the S6000 variant will raise this to 16.
