Please ack this as I need to apply it to the drm-misc tree. Or we need a
stable branch with this patch.
v3:
- Rework arm_lpae_prot_to_pte as written by Robin
- Fill in complete register values for TRANSTAB and MEMATTR registers
drivers/iommu/io-pgtable-arm.c | 93
drm-misc or we need a stable branch.
A git branch is here[1].

Use the for_each_of_cpu_node iterator to iterate over cpu nodes. This
has the side effect of defaulting to iterating using "cpu" node names in
preference to the deprecated (for FDT) device_type == "cpu".

more strict by only looking in /cpus child nodes rather
than any node with the device_type == cpu. The iterator also honors the
status property which is often forgotten.
I've only tested on ARM under QEMU and compiled powerpc.
