v4:
- Fixed a few "subordinate clauses" (SC) cases [Alex]
- Reword in ioctl_userfaultfd.2 to use bold font for the two modes referenced,
so as to be clear on what is "both" referring to [Alex]

v3:
- Don't use "Currently", instead add "(since x.y)" mark where proper [Alex]
- Always use semantic newlines across the whole patchset [Alex]
- Use quote when possible, rather than escapes [Alex]
- Fix one missing replacement of ".BR" -> ".B" [Alex]
- Some other trivial rephrases here and there when fixing up above

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.
