Hi,

This is v2 of a series that fixes up build errors and warnings for at
least the 64-bit builds on x86 with clang.

There are lots of changes since v1 [1], thanks to reviews from Peter Xu, David
Hildenbrand, and Muhammad Usama Anjum. These include:

* Using "make headers", and documenting that prerequisite as well.
* Better ways to avoid clang's Wformat-security warnings
* Added Cc's, ack-by's, reviewed-by's.
* Updated commit log messages.

The series also includes an optional "improvement" of moving some uffd
code into uffd-common.[ch], which is proving to be somewhat
controversial, and so if that doesn't get resolved, then patches 9 and
10 may just get dropped. They are not required in order to get a clean
build, now that "make headers" is happening.

thanks,
