Merge tag 'powerpc-5.1-6' of git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux 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" * tag 'powerpc-5.1-6' of git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux: powerpc/mm_iommu: Allow pinning large regions powerpc/mm_iommu: Fix potential deadlock powerpc/mm/radix: Make Radix require HUGETLB_PAGE
