Subject: linux-next: manual merge of the iommu tree with the rdma-fixes tree

Hi all,

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

  drivers/infiniband/hw/usnic/usnic_uiom.c

between commit:

  b7e08a5a63a1 ("RDMA/usnic: use iommu_map_atomic() under spin_lock()")

from the rdma-fixes tree and commits:

  1369459b2e21 ("iommu: Add a gfp parameter to iommu_map()")
  4dc6376af596 ("iommu: Remove iommu_map_atomic()")

from the iommu tree.

I fixed it up (see below) and can carry the fix as necessary. This
is now fixed as far as linux-next is concerned, but any non trivial
conflicts should be mentioned to your upstream maintainer when your tree
is submitted for merging.  You may also want to consider cooperating
with the maintainer of the conflicting tree to minimise any particularly
complex conflicts.

Cheers,
Stephen Rothwell
