#     powerpc/mm/64s: Drop p4d_leaf()
#     
#     Because 64-bit Book3S uses pgtable-nop4d.h, the P4D is folded into the
#     PGD. So P4D entries are actually PGD entries, or vice versa.
#     
#     The other way to think of it is that the P4D is a single entry page
#     table below the PGD. Zero bits of the address are needed to index into
#     the P4D, therefore a P4D entry maps the same size address space as a PGD
#     entry.
#     
#     As explained in the previous commit, there are no huge page sizes
#     supported directly at the PGD level on 64-bit Book3S, so there are also
#     no huge page sizes supported at the P4D level.
#     
#     Therefore p4d_is_leaf() can never be true, so drop the definition and
#     fallback to the default implementation that always returns false.
