Subject: [PATCH v2 0/5] userfaultfd man page updates

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).

Axel Rasmussen (5):
  ioctl_userfaultfd.2: describe two-step feature handshake
  ioctl_userfaultfd.2: correct and update UFFDIO_API ioctl error codes
  ioctl_userfaultfd.2: clarify the state of the uffdio_api structure on
    error
  ioctl_userfaultfd.2: fix / update UFFDIO_REGISTER error code list
  ioctl_userfaultfd.2: document new UFFDIO_POISON ioctl
