    Subject[patch 071/164] mn10300: set ARCH_KMALLOC_MINALIGN
    2.6.33-stable review patch.  If anyone has any objections, please let me know.

    ------------------

    From: FUJITA Tomonori <fujita.tomonori@lab.ntt.co.jp>

    commit 6cdafaae41d52e6ef9a5c5be23602ef083e4d0f9 upstream.

    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.
