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.
