Do you mind if I take this but rework the destination names in the process?

I don't like having eg. book3s64/pgtable-book3s64.c

And some of the other names could use a bit of cleanup too.

What about:

 arch/powerpc/mm/{hash64_4k.c => book3s64/hash_4k.c}
 arch/powerpc/mm/{hash64_64k.c => book3s64/hash_64k.c}
 arch/powerpc/mm/{hugepage-hash64.c => book3s64/hash_hugepage.c}
 arch/powerpc/mm/{hugetlbpage-hash64.c => book3s64/hash_hugetlbpage.c}
 arch/powerpc/mm/{hash_native_64.c => book3s64/hash_native.c}
 arch/powerpc/mm/{pgtable-hash64.c => book3s64/hash_pgtable.c}
 arch/powerpc/mm/{tlb_hash64.c => book3s64/hash_tlb.c}
 arch/powerpc/mm/{hash_utils_64.c => book3s64/hash_utils.c}
 arch/powerpc/mm/{mmu_context_iommu.c => book3s64/iommu_api.c}
 arch/powerpc/mm/{mmu_context_book3s64.c => book3s64/mmu_context.c}
 arch/powerpc/mm/{pgtable-book3s64.c => book3s64/pgtable.c}
 arch/powerpc/mm/{hugetlbpage-radix.c => book3s64/radix_hugetlbpage.c}
 arch/powerpc/mm/{pgtable-radix.c => book3s64/radix_pgtable.c}
 arch/powerpc/mm/{tlb-radix.c => book3s64/radix_tlb.c}
