The ARCH_KMALLOC_MINALIGN reduction series defines a generic
ARCH_DMA_MINALIGN in linux/cache.h:


Unfortunately, this causes a duplicate definition warning for
microblaze, powerpc (32-bit only) and sh as these architectures define
ARCH_DMA_MINALIGN in a different file than asm/cache.h. Move the macro
to asm/cache.h to avoid this issue and also bring them in line with the
other architectures.

Andrew, if the arch maintainers cc'ed are fine with such change, could
you please take these three patches together with the

Thank you.
