[Based on linus/master, commit ac08b1c68d1b which should contain the recent -mm
 pull, if not applicable, I can repost anytime]

v3:
- Patch "mm: Add zap_skip_check_mapping() helper"
  - 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

v2:
- Patch "mm: Clear vmf->pte after pte_unmap_same() returns"
  - Remove one comment [David]
- Collect r-b for patch 2/3
- Rewrite the last two patches to drop ZAP_FLAG_CHECK_MAPPING, dropping
  Alistair's r-b on patch 5 because it changed [David, Matthew]

===== v1 cover letter =====

I picked up these patches from uffd-wp v5 series here:

https://lore.kernel.org/lkml/20210715201422.211004-1-peterx@redhat.com/

IMHO all of them are very nice cleanups to existing code already, they're all
small and self-contained.  They'll be needed by uffd-wp coming series.  I would
appreciate if they can be accepted earlier, so as to not carry them over always
with the uffd-wp series.

I removed some CC from the uffd-wp v5 series to reduce the noise, and added a
few more into it.

Reviews are greatly welcomed, thanks.
