IIRC the memory from vm_phys_alloc_contig() can be released like any
other page; the interface should just be fetching a specific page.
How far off is the page wire count? I'm assuming it's hitting the
assert that it's > 1?
I think vm_page_free() is the right interface to free the page again,
so the wire count being off presumably means someone else wired it on
you; do you know what code did it? If no one else has a reference to
the page anymore then setting the wire count to 1, while a hack,
should be safe.
Yes, vm_page_free() can be used to free a single page that was returned
by vm_phys_alloc_contig().
