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 69dcf3db03
Author: FUJITA Tomonori <fujita.tomonori@lab.ntt.co.jp>

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.
