From 8507bb0062bff1431bbcce921efe5cd1186fcff2 Mon Sep 17 00:00:00 2001 From: David Howells Date: Fri, 28 May 2010 10:41:16 +0100 Subject: [PATCH] FRV: ARCH_KMALLOC_MINALIGN was already defined ARCH_KMALLOC_MINALIGN was already defined in asm/mem-layout.h and so shouldn't have been added to asm/cache.h as well, but rather altered in place. The commit that added it to asm/cache.h was: commit 69dcf3db03626c4f18de624e8632454ea12ff260 Author: FUJITA Tomonori Date: Mon May 24 14:32:54 2010 -0700 frv: set ARCH_KMALLOC_MINALIGN Architectures that handle DMA-non-coherent memory need to set ARCH_KMALLOC_MINALIGN to make sure that kmalloc'ed buffer is DMA-safe: the buffer doesn't share a cache with the others.
