Per discussion w/ chuck and chuck, restructure the md page stuff to use a structure called "vm_page_md", and use __HAVE_VM_PAGE_MD and __HAVE_PMAP_PHYSSEG. 2001-05-01 06:19:13 +04:00			`/* $NetBSD: vmparam.h,v 1.29 2001/05/01 02:19:20 thorpej Exp $ */`

			`#define VM_PHYSSEG_MAX 4`
Add a VM_MDPAGE_MEMBERS macro that defines pmap-specific data for each vm_page structure. Add a VM_MDPAGE_INIT() macro to init this data when pages are initialized by UVM. These macros are mandatory, but ports may #define them to nothing if they are not needed/used. This deprecates struct pmap_physseg. As a transitional measure, allow a port to #define PMAP_PHYSSEG so that it can continue to use it until its pmap is converted to use VM_MDPAGE_MEMBERS. Use all this stuff to eliminate a lot of extra work in the Alpha pmap module (it's smaller and faster now). Changes to other pmap modules will follow. 2001-04-30 02:44:31 +04:00
