  * Encode and decode a swap entry.
- * Each PTE in a process VM's page table is either:
- *   "present" -- valid and not swapped out, protection bits are meaningful;
- *   "not present" -- which further subdivides in these two cases:
- *      "none" -- no mapping at all; identified by pte_none(), set by pte_clear(
- *      "swapped out" -- the page is swapped out, and the SWP macros below
- *                      are used to store swap file info in the PTE itself.
  *
- * In the Xtensa processor MMU, any PTE entries in user space (or anywhere
- * in virtual memory that can map differently across address spaces)
- * must have a correct ring value that represents the RASID field that
- * is changed when switching address spaces.  Eg. such PTE entries cannot
- * be set to ring zero, because that can cause a (global) kernel ASID
- * entry to be created in the TLBs (even with invalid cache attribute),
- * potentially causing a multihit exception when going back to another
- * address space that mapped the same virtual address at another ring.
- *
- * SO: we avoid using ring bits (_PAGE_RING_MASK) in "not present" PTEs.
- * We also avoid using the _PAGE_VALID bit which must be zero for non-present
- * pages.
- *
- * We end up with the following available bits:  1..3 and 7..31.
- * We don't bother with 1..3 for now (we can use them later if needed),
- * and chose to allocate 6 bits for SWP_TYPE and the remaining 19 bits
- * for SWP_OFFSET.  At least 5 bits are needed for SWP_TYPE, because it
- * is currently implemented as an index into swap_info[MAX_SWAPFILES]
- * and MAX_SWAPFILES is currently defined as 32 in <linux/swap.h>.
- * However, for some reason all other architectures in the 2.4 kernel
- * reserve either 6, 7, or 8 bits so I'll not detract from that for now.  :)
- * SWP_OFFSET is an offset into the swap file in page-size units, so
- * with 4 kB pages, 19 bits supports a maximum swap file size of 2 GB.
- *
- * FIXME:  2 GB isn't very big.  Other bits can be used to allow
- * larger swap sizes.  In the meantime, it appears relatively easy to get
- * around the 2 GB limitation by simply using multiple swap files.
+ * Format of swap pte:
+ *  bit    0       MBZ
+ *  bit    1       page-file (must be zero)
+ *  bits   2 -  3  page hw access mode (must be 11: _PAGE_INVALID)
+ *  bits   4 -  5  ring protection (must be 01: _PAGE_USER)
+ *  bits   6 - 10  swap type (5 bits -> 32 types)
+ *  bits  11 - 31  swap offset / PAGE_SIZE (21 bits -> 8GB)
+ 
+ * Format of file pte:
+ *  bit    0       MBZ
