Subject: linux-next: build failure after merge of the net-next tree

Hi all,

After merging the net-next tree, today's linux-next build (x86_64
allmodconfig) failed like this:

net/xdp/xsk_buff_pool.c:7:10: fatal error: linux/dma-noncoherent.h: No such file or directory
    7 | #include <linux/dma-noncoherent.h>
      |          ^~~~~~~~~~~~~~~~~~~~~~~~~

Caused by commit

  1c1efc2af158 ("xsk: Create and free buffer pool independently from umem")

interacting with commit

  a3cf77774abf ("dma-mapping: merge <linux/dma-noncoherent.h> into <linux/dma-map-ops.h>")

from the dma-mapping tree.

I have applied teh following merge fix patch.

From: Stephen Rothwell <sfr@...b.auug.org.au>
