thorpej cf67ac7122 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.

thorpej 2b27ac7a99 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.

reinoud 3043022c3a Added extra kernel vm by moving up vidc space 2001-02-18 00:56:42 +00:00
chs c29a1b4461 allow ports to override PAGER_MAP_SIZE in machine/vmparam.h.
some ports (such as arm32) don't have enough KVA for the
increased default size once the UBC mapping is also present.

thorpej b8073b401b Garbage-collect the VM_MBUF_SIZE constant. Instead, use the size
(nmbclusters * mclbytes), so that the right amount of KVA space is
allocated if those variables are patched.

mycroft 1bb64b0636 __SWAP_BROKEN is no longer useful here. 1999-03-23 19:16:03 +00:00
mark f88d8c6a35 In the light of PRs 7122 & 7123 temporarily define __SWAP_BROKEN until
the problem these bug reports described is fixed and they are closed.

chuck 66226eb6ff remove non-MNN code 1999-01-16 20:11:03 +00:00
mark 3e217a0157 Remove the definition of CURRENT_PAGEDIR_HOLE and CURRENT_PAGEDIR_BASE
as they are no longer reference.
Move ALT_PAGE_TBLS_BASE from 0xf3c00000 to 0xf0c00000.
Increase the size of the KERNEL_VM_SIZE by 16MB now that 0xf3xxxxxx is free.

mark cda0e37703 Collect various kernel constants together and define them in all one
place (some moved from param.h)
Define several constants such as page table addresses in terms of other
constants.
Increase some of the limits :
  MAXTSIZ	8MB -> 16MB
  DFLDSIZ	16MB -> 128MB
  MAXDSIZ	256MB -> 512MB
  DFLSSIZ	512KB -> 2MB
