This supercedes: [PATCH kernel] powerpc/mm_iommu: Allow pinning large regions [PATCH kernel 1/2] powerpc/mm_iommu: Prepare for less locking [PATCH kernel 2/2] powerpc/mm_iommu: Fix potential deadlock This is based on sha1 5e7a8ca31926 Linus Torvalds "Merge branch 'work.aio' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs".
