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

Hi all,

After merging the iommu tree, today's linux-next build (arm
multi_v7_defconfig) failed like this:

drivers/iommu/iommu.c: In function 'iommu_subsys_init':
drivers/iommu/iommu.c:123:38: error: implicit declaration of function 'sme_active'; did you mean 'cpu_active'? [-Werror=implicit-function-declaration]
  123 |   if (iommu_default_passthrough() && sme_active()) {
      |                                      ^~~~~~~~~~
      |                                      cpu_active

Caused by commit

  2cc13bb4f59f ("iommu: Disable passthrough mode when SME is active")

sme_active() seems to be only relevant to X86.

I have reverted that commit for today.
