v3:

  - In zap_skip_check_mapping() check zap_mapping first [Alistair]
- Patch "mm: Add ZAP_FLAG_SKIP_SWAP and zap_flags":
  - Fix English errors in commit message [David]
  - Drop paragraph mentioning commit 22061a1ffabd in commit msg
  - Set ZAP_FLAG_SKIP_SWAP for unmap_mapping_page() too
- Pick up r-bs

Ping - patches 1-4 have at least 1 ack already, the last patch is missing ack.

The change is quite straightforward as right now we apply SKIP_SWAP to all
"details" users of zapping process, so no functional change intended.  It'll be
important for uffd-wp in the future because uffd-wp will start to use "details"
without setting SKIP_SWAP.

It would be great if anyone could help have a look at the last patch, thanks.
