Axel Rasmussen 0dc6a0929f FROMGIT: userfaultfd: update documentation to describe minor fault handling
Reword / reorganize things a little bit into "lists", so new features /
modes / ioctls can sort of just be appended.

Describe how UFFDIO_REGISTER_MODE_MINOR and UFFDIO_CONTINUE can be used to
intercept and resolve minor faults.  Make it clear that COPY and ZEROPAGE
are used for MISSING faults, whereas CONTINUE is used for MINOR faults.
