From cbd2d9d8fcd9d2a46d71d0703a76773c20383c66 Mon Sep 17 00:00:00 2001 From: Paul Mundt Date: Mon, 4 Jun 2007 15:46:56 +0900 Subject: sh: Default to 4-byte alignment for SLUB objects. Slub currently defaults to 8-byte alignment for the kmalloc and slab minalign values, where 4 will suffice. In the slab case BYTES_PER_WORD == 4 already, so defining the minalign values outright doesn't cause any regressions there either.
