Hi all,

After merging the rpmsg tree, today's linux-next build (arm64 defconfig)
failed like this:

drivers/remoteproc/qcom_q6v5_adsp.c: In function 'adsp_map_carveout':
drivers/remoteproc/qcom_q6v5_adsp.c:369:15: error: too few arguments to function 'iommu_map'
  369 |         ret = iommu_map(rproc->domain, iova, adsp->mem_phys,
      |               ^~~~~~~~~
In file included from drivers/remoteproc/qcom_q6v5_adsp.c:12:
include/linux/iommu.h:473:12: note: declared here
  473 | extern int iommu_map(struct iommu_domain *domain, unsigned long iova,
      |            ^~~~~~~~~

Caused by commit

  f22eedff28af ("remoteproc: qcom: Add support for memory sandbox")

interacting with commit

  1369459b2e21 ("iommu: Add a gfp parameter to iommu_map()")

from the iommu tree.

I have applied the following merge fix patch.
