Catalin Marinas b035f5a6d8 mm: slab: reduce the kmalloc() minimum alignment if DMA bouncing possible 
If an architecture opted in to DMA bouncing of unaligned kmalloc() buffers
(ARCH_WANT_KMALLOC_DMA_BOUNCE), reduce the minimum kmalloc() cache
alignment below cache-line size to ARCH_KMALLOC_MINALIGN.
