These additions of the code should have been done in a separate patch.
This has been observed in some of the previous patches as well. If the
commit message says that PTE definitions need to be moved then the
patch only needs to move them, not change them anyway while on the move.
Any changes to code should be done in separate patch. That will keep
the change log clean, logical and makes it easy to track and understand.

powerpc/mm: Move hash64 PTE bits from book3s/64/pgtable.h to hash.h
This enables us to keep hash64 related bits together, and makes it easy
to follow.
