Do not create kmalloc() caches which are not aligned to dma_get_cache_alignment(). There is no functional change since for current architectures defining ARCH_DMA_MINALIGN, ARCH_KMALLOC_MINALIGN equals ARCH_DMA_MINALIGN (and dma_get_cache_alignment()). On architectures without a specific ARCH_DMA_MINALIGN, dma_get_cache_alignment() is 1, so no change to the kmalloc() caches.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
