.SH "DESCRIPTION"
.PP
For an object-based mapped page, find all the places it is mapped and
check/clear the referenced flag.  This is done by following the page->mapping
pointer, then walking the chain of vmas it holds.  It returns the number
of references it found.
.PP
This function is only called from page_referenced for object-based pages.
