#     powerpc/8xx: Add support for huge pages on VMAP and VMALLOC
#     
#     powerpc 8xx has 4 page sizes:
#     - 4k
#     - 16k
#     - 512k
#     - 8M
#     
#     At the time being, vmalloc and vmap only support huge pages which are
#     leaf at PMD level.
#     
#     Here the PMD level is 4M, it doesn't correspond to any supported
#     page size.
#     
#     For the time being, implement use of 16k and 512k pages which is done
#     at PTE level.
#     
#     Support of 8M pages will be implemented later, it requires vmalloc to
#     support hugepd tables.
