This series includes only the remaining patches not applied from v1, with review comments addressed. This series is based on the "contrib" branch. Changelog: v1->v2: - In patch 1 (patch 5 in v1), change "after" to "since" for consistency and to be clear that we mean 4.11+ (inclusive). - In patch 2 (patch 7 in v1), reorder error codes alphabetically (EINVAL then EPERM). - In patch 3 (patch 8 in v1), resolve conflicts with earlier review comments. Original cover letter: Various updates for userfaultfd man pages. To summarize the changes: - Correctly / fully describe the two-step feature support handshake process. - Describe new UFFDIO_POISON ioctl. - Other small improvements (missing ioctls, error codes, etc).
