process_madvise.2: Consistently use the term 'advice'
...
The page used 'hint' and 'advice' synonymously. This leaves the
reader wondering if the terms mean the same thing, or different
things. They mean the same thing, so use just one term.

Rather than repeating the description of MADV_COLD and MADV_PAGEOUT
in two pages, centralize the discussion in madvise(2), and refer
from process_madvise(2) ro madvise(2).

process_madvise.2: Restructure the text in DESCRIPTION a little
...
The 'advice' subsection fell in the middle of other text in the
DESCRIPTION, which is a little confusing. Instead, move that
subsection to the end of the DESCRIPTION, and make some other
minor text reorganization so that related details are placed in
the same paragraphs.
