* migration: Use non-atomic ops for clear log bitmapPeter Xu2022-11-212-5/+9
| | | | | | | | | | | | | | | | Since we already have bitmap_mutex to protect either the dirty bitmap or the clear log bitmap, we don't need atomic operations to set/clear/test on the clear log bitmap. Switching all ops from atomic to non-atomic versions, meanwhile touch up the comments to show which lock is in charge. Introduced non-atomic version of bitmap_test_and_clear_atomic(), mostly the same as the atomic version but simplified a few places, e.g. dropped the "old_bits" variable, and also the explicit memory barriers.

Drop the explicit PAGE_ANON check, since anonymous mappings are expected to have PAGE_PASSTHROUGH anyway. Add PAGE_PASSTHROUGH to PAGE_STICKY in order to keep it on mprotect().
