[PATCH v2 0/4] man2: udpate mm/userfaultfd manpages to latest

[Peter Xu]

v2 changes:
- Fix wordings as suggested [MikeR]
- convert ".BR" to ".B" where proper for the patchset [Alex]
- rearrange a few lines in the last two patches where they got messed up
- document more things, e.g. UFFDIO_COPY_MODE_WP; and also on how to resolve a
  wr-protect page fault.

There're two features missing in current manpage, namely:

  (1) Userfaultfd Thread-ID feature
  (2) Userfaultfd write protect mode

There's also a 3rd one which was just contributed from Axel - Axel, I think it
would be great if you can add that part too, probably after the whole
hugetlbfs/shmem minor mode reaches the linux master branch.

Please review, thanks.
