Alan Cox 920da7e4d2 Relax the object type restrictions on vm_page_alloc_contig(). Specifically, ...

add support for object types that were previously prohibited because they
could contain PG_CACHED pages.

Roughly halve the number of radix trie operations performed by
vm_page_alloc_contig() using the same approach that is employed by
vm_page_alloc().  Also, eliminate the radix trie lookup performed with the
free page queues lock held.

Tidy up the handling of radix trie insert failures in vm_page_alloc() and
vm_page_alloc_contig().
