uml: fix page table data sizes
Get the sizes of various pieces of data right when using three-level
page tables. pgd and pmd entries remain at 32 bits in a 32-bit
compilation because page tables will remain in low memory. So,
PGDIR_SHIFT, the PTRS_PER_* values, set_pud, set_pmd are conditional
on 64BIT.
More use of phys_t is made when there are physical memory addresses
floating around.
ObCheckpatchViolationJustification - the new typedef is an alternate
definition of pmd_t, which I can't really live without.
