This is the result of my my build tests on 3.9-rc1, mostly bugs
that I had not caught before the merge window, or where the fix
for some reason has not yet made it in.
I hope the subsystem maintainers can take care of applying these,
for the arch/arm/mach-* patches I can either apply them directly
The OMAP IOMMU driver intentionally fails to build on OMAP1
platforms, so we should not allow enabling it there.

fault
and the driver would crash.
IF I turn off IOMMU there is
