Subject: [PATCH v2 1/2] asm-generic: Make dma-contiguous.h a mandatory include/asm header
Date: Fri, 17 Jan 2020 09:03:31 +0100	[thread overview]
Message-ID: <0274919c5e3b134df19d943f99cb7e84e5135ccd.1579248206.git.michal.simek@xilinx.com> (raw)
In-Reply-To: <cover.1579248206.git.michal.simek@xilinx.com>

dma-continuguous.h is generic for all architectures except arm32 which has
its own version.

Similar change was done for msi.h by commit a1b39bae16a6
("asm-generic: Make msi.h a mandatory include/asm header")

Suggested-by: Christoph Hellwig <hch@infradead.org>
