Re: powerpc: set ARCH_KMALLOC_MINALIGN if CONFIG_NOT_COHERENT_CACHE=y

In article [ref] you write:

Ensure that buffers returned by kmalloc do not share a cache
line with other data when doing non-cache-coherent I/O.

Eugene Surovegin points out that ARCH_KMALLOC_MINALIGN
doesn't work as avertised.

This patch doesn't work.

Thanks,
