Added ability to detect sequential faults and DTRT. (swap_pager.c)
Added hook for pmap_prefault() and use symbolic constant for new third argument to vm_page_alloc() (vm_fault.c, various) Changed the way that upages and page tables are held. (vm_glue.c) Fixed architectural flaw in allocating pages at interrupt time that was introduced with the merged cache changes. (vm_page.c, various) Adjusted some algorithms to acheive better paging performance and to accomodate the fix for the architectural flaw mentioned above. (vm_pageout.c) Fixed pbuf handling problem, changed policy on handling read-behind page. (vnode_pager.c) Submitted by: John Dyson
