Pull powerpc fixes from Michael Ellerman:
"A one-liner to make our Radix MMU support depend on HUGETLB_PAGE. We
use some of the hugetlb inlines (eg. pud_huge()) when operating on the
linear mapping and if they're compiled into empty wrappers we can
corrupt memory.
Then two fixes to our VFIO IOMMU code. The first is not a regression
but fixes the locking to avoid a user-triggerable deadlock.
The second does fix a regression since rc1, and depends on the first
fix. It makes it possible to run guests with large amounts of memory
again (~256GB).
Thanks to Alexey Kardashevskiy"
