This will enable the use of SR.RB register bank usage. Processors
that are lacking this bit must have another method in place for
accomplishing what is taken care of by the banked registers.

* Encode and de-code a swap entry

* Constraints:
* _PAGE_FILE at bit 0
* _PAGE_PRESENT at bit 8
* _PAGE_PROTNONE at bit 9
*
* For the normal case, we encode the swap type into bits 0:7 and the
* swap offset into bits 10:30. For the 64-bit PTE case, we keep the
* preserved bits in the low 32-bits and use the upper 32 as the swap
* offset (along with a 5-bit type), following the same approach as x86
* PAE. This keeps the logic quite simple, and allows for a full 32
* PTE_FILE_MAX_BITS, as opposed to the 29-bits we're constrained with
* in the pte_low case.
*
* As is evident by the Alpha code, if we ever get a 64-bit unsigned
* long (swp_entry_t) to match up with the 64-bit PTEs, this all becomes
* much cleaner..
*
* NOTE: We should set ZEROs at the position of _PAGE_PRESENT
* and _PAGE_PROTNONE bits
