I think cut out the reference to PAGE_CACHE_SIZE. mincore()'s current
kernel implementation may indeed involve PAGE_CACHE_SIZE, but I believe
that if PAGE_CACHE_SIZE is ever changed away from PAGE_SIZE, that will
be a kernel implementation detail, which should not affect its interfaces
with user-space. You're right to SEE ALSO getpagesize: really even the
references to PAGE_SIZE should defer to getpagesize e.g. the mmap man
page (on my RH7 anyway) says "offset should ordinarily be a multiple of
the page size returned by getpagesize(2)"; but it may get tiresome to use
that circumlocution ("the artist formerly known as Prince") everywhere.
