Hey Alex / Michael,

This series adds MADV_COLLAPSE (expected for Linux 6.1) documentation to
madvise(2) and process_madvise(2).  A few prerequisite patches are included to
fix up existing MADV_HUGEPAGE and process_madvise(2) documentation, as well as
add some additional clarity for madvise(2) "advice" probing.

Series applies on man-pages-6.00, and I've attempted to use semantic newlines,
though I can't claim I've made the right choices everywhere for long clauses.

Thanks,
Zach
