Looking at the code, it seems that vm_page_unwire() only requires the
page to be locked if it is managed. As it was acquired by
contigmalloc, the page should be unmanaged so that should be ok.
I am confused as to why vm_page_unwire() does not require the page to
be locked if the page is unmanaged. What is synchronizing the
accesses to m->wire_count?
