Changes:
v2:
* it does not try to introduce a realmode search function.
Instead, liobn-to-iommu-group lookup is done by VFIO KVM device
in virtual mode and the result (iommu_group pointer) is cached
in kvm_arch so the realmode handlers do not use VFIO KVM d
Unaligned stores take alignment exceptions on POWER7 running in little-endian.
This is a dumb little-endian base memcpy that prevents unaligned stores.
It is replaced by the VMX memcpy at boot.

fsl_ssi was originally PPC-only, but it now supports PPC and ARM. You
can see that from the git history.
If there are any comments that say PPC but are not PPC-specific, that

The wrapper script needs an explicit rule for the "of" boot

Yes, find it.
The comments is in "sound/soc/fsl/Makefile" :

But fsl-spdif.o is also under it.
And this is also support

Good catch, we should have preemption disabled while ever we have a

Currently the ppc-of driver uses the compatibility string
"usb-ehci". This means platforms that use device-tree and implement an
EHCI compatible interface have to either use the ppc-of driver or add
a compatible line to the ehci-platform driver. It would be more
appropriate for the platform driver
