vm_page_busy, vm_page_flash, vm_page_wakeup -- handle the busying and
unbusying of a page
These functions handle the busying, unbusying and notification of the
unbusying of a page.
vm_page_busy() sets the PG_BUSY flag in the page.
vm_page_flash() checks to see if there is anybody waiting on the page
(PG_WANTED will be set), and if so, clears the PG_WANTED flag and notifies
whoever is waiting via wakeup().
vm_page_wakeup() clears the PG_BUSY flag on the page, and calls
vm_page_flash() in case somebody has been waiting for it.
