Linus Torvalds 0d82044e1b 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).
