Sorry for that. Vim usually did the wrapping job for me so I didn't pay much attention on it. I will be more careful next time.

This patch fixes a bug in vm_page_grab_contiguous_pages, which fails to maintain the free vm page queue correctly.
vm_page_grab_contiguous_pages isn't used by the current gnumach. but I need this function to allocate contiguous physical pages for DMA buffers which are required by user-level drivers.
