23 * With get_user_pages_fast, we walk down the pagetables without
24 * taking any locks. For this we would like to load the pointers
25 * atomically, but that is not possible with 64-bit PTEs. What
26 * we do have is the guarantee that a pte will only either go
27 * from not present to present, or present to not present or both
28 * -- it will not switch to a completely different present page
29 * without a TLB flush in between; something that we are blocking
30 * by holding interrupts off.
31 *
32 * Setting ptes from not present to present goes:
33 * ptep->pte_high = h;
34 * smp_wmb();
35 * ptep->pte_low = l;
36 *
37 * And present to not present goes:
38 * ptep->pte_low = 0;
39 * smp_wmb();
40 * ptep->pte_high = 0;
41 *
42 * We must ensure here that the load of pte_low sees l iff pte_high
43 * sees h. We load pte_high *after* loading pte_low, which ensures we
44 * don't see an older value of pte_high. *Then* we recheck pte_low,
45 * which ensures that we haven't picked up a changed pte high. We might
46 * have got rubbish values from pte_low and pte_high, but we are
47 * guaranteed that pte_low will not have the present bit set *unless*
48 * it is 'l'. And get_user_pages_fast only operates on present ptes, so
49 * we're safe.
50 *
51 * gup_get_pte should not be used or copied outside gup.c without being
52 * very careful -- it does not atomically load the pte or anything that
53 * is likely to be useful for you.
