Based on v5.12-rc2-mmots-2021-03-08-21-54. I wanted to cleanup userfaultfd.c fault handling for a long time. If it's not cleaned, when the new code grows the file it'll also grow the size that needs to be cleaned... This is my attempt to cleanup the userfaultfd selftest on fault handling, to use an err() macro instead of either fprintf() or perror() then another exit() call. The huge cleanup is done in the last patch. The first 4 patches are some other standalone cleanups for the same file, so I put them together. Please review, thanks.
