Subject: [PATCH 1/2] mm: slab: fix comment for ARCH_KMALLOC_MINALIGN

From: Andrey Konovalov <[email protected]>

The comment next to the ARCH_KMALLOC_MINALIGN definition says that
ARCH_KMALLOC_MINALIGN can be defined in arch headers. This is incorrect:
it's actually ARCH_DMA_MINALIGN that can be defined there.

Fix the comment.
