Anshuman Khandual 08978fc3b0 mm/ptdump: split effective_prot() into level specific callbacks 
Last argument in effective_prot() is u64 assuming pxd_val() returned value
(all page table levels) is 64 bit.  pxd_val() is very platform specific
and its type should not be assumed in generic MM.

Split effective_prot() into individual page table level specific callbacks
which accepts corresponding pxd_t argument instead and then the
subscribing platform (only x86) just derive pxd_val() from the entries as
required and proceed as earlier.
