Lines Matching full:swap
41 * To make nonlinear swap work according to the more recent
43 * the PTE describes MMU programming or swap space.
332 /* __pte_to_swp_entry - extract swap entry from PTE */
335 /* __swp_entry_to_pte - extract PTE from swap entry */
362 * Swap/file PTE definitions. If _PAGE_PRESENT is zero, the rest of the PTE is
363 * interpreted as swap information. The remaining free bits are interpreted as
364 * swap type/offset tuple. Rather than have the TLB fill handler test
366 * all zeros for swap entries, which speeds up the miss handler at the cost of
369 * and not much swap space.
371 * Format of swap PTE:
373 * bits 1-5: swap type (arch independent layer uses 5 bits max)
376 * bits 13-31: bits 22:4 of swap offset
382 /* Used for swap PTEs */
