From 273fca0ecad9305247043815e185d1bfd04047d4 Mon Sep 17 00:00:00 2001 From: "David S. Miller" <davem@davemloft.net> Date: Tue, 18 May 2010 15:23:58 -0700 Subject: [PATCH] sparc: Define ARCH_SLAB_MINALIGN Because SLOB fancies being different, the default minimum alignment is only "unsigned long" instead of SLAB/SLUB where the default is "unsigned long long" The inconsistency makes no sense and is asking for trouble, but define ARCH_SLAB_MINALIGN to get it right in all cases even after they fix the inconsistency.
