Hi all,

Today's linux-next merge of the akpm-current tree got a conflict in:

  arch/arm/include/asm/xen/page-coherent.h

between commits:

  bef4d2037d2143a ("xen/arm: consolidate page-coherent.h")
  60d8cd572f655aa ("arm64/xen: fix xen-swiotlb cache flushing")

from the dma-mapping tree and commit:

  46d5fa030cd9225 ("mm: introduce compound_nr()")

from the akpm-current tree.  The former appear to make the latter
redundant so I resolved by dropping the relevant portions of the
commit from the akpm tree.
