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 <fujita.tomonori@lab.ntt.co.jp> 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.
