Hi Linus,

Please pull some more powerpc fixes for 5.1.

I was 50/50 on whether these were worthy of sending at rc6, but decided I would
send them as they're in obscure areas of the code and they do fix user-visible
bugs.

cheers

  powerpc/mm_iommu: Allow pinning large regions (2019-04-17 21:36:51 +1000)

- ------------------------------------------------------------------
powerpc fixes for 5.1 #6

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.
