2016-09-21Redefine what an external page isRichard Braun
Instead of a "page considered external", which apparently takes into account whether a page is dirty or not, redefine this property to reliably mean "is in an external object". This commit mostly deals with the impact of this change on the page allocation interface. * i386/intel/pmap.c (pmap_page_table_page_alloc): Update call to vm_page_grab. * kern/slab.c (kmem_pagealloc_physmem): Use vm_page_grab instead of vm_page_grab_contig.
