Move struct vm_page_md definition from vmparam.h to pmap.h, because
it's used only by pmap.  vmparam.h has definitions for wider
audience.

All GENERIC kernels build tested, except ia64.

powerpc/include/booke/vmparam.h has one too, but it has no pmap.h,
so it's left as is.

Remove incomplete, never worked dynamic run-time memory registration
(uvm_page_physload(9)).  This functionality will be re-added later.

Remove the unfinished code to add a memory segment after uvm_page_init().
It doesn't even compile.

(In the future, we should allocate struct vm_page [] on the added memory
segment for NUMA's sake.)

Use VM_PAGE_TO_MD().  Only compile tested.

Convert all VM_MDPAGE_INIT()'s to take struct vm_page_md * and paddr_t.

Commit is split, to avoid a "too many arguments" protocol error.

Remove SHMMAXPGS from all kernel configs. Dynamically compute the
initial limit as 1/4 of the physical memory. Ensure the limit is at
least 1024 pages, the old default on most platforms.

Max data size -> 512MB; default stack size -> 8MB.

Move UCB-licensed code from 4-clause to 3-clause licence.

Patches provided by Joel Baker in PR 22364, verified by myself.

Don't define PAGE_SIZE, etc. in terms of NBPG, rather use the same
logic as used by <machine/param.h> to define constant PAGE_SIZE if
possible.

Also define the minimum and maximum PAGE_SIZE that might appear in
any given configuration (4K and 8K, respectively).

Move the PV list header into the VM page vm_page_md structure.
Also, start using a spin lock to protect PV list operations.

Sync with HEAD.

Use __LDPGSZ (which must be == USRTEXT) as the text address for a.out
executables, and eliminate the USRTEXT constant, which was only used
by the a.out exec code.

Pull up revision 1.31 (requested by thorpej in ticket #763):
  Increase the default stack limit to 2M (from 512K on sparc
  and 1M on sparc64).

Catch up to -current.

on sparc64).

MAXSLP is defined to be a machine-independent scheduling parameter,

file vmparam.h was added on branch nathanw_sa on 2002-01-08 00:27:40 +0000

remove bogus curly braces from a structure forward-declaration.

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.

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.

Sync with HEAD.

* Make PAGE_SIZE et.al. constants, if possible.
* Add pvlist pointer to `struct pmap_physseg'
* Because of the above, add guard against multiple inclusions.

Update thorpej_scsipi to -current as of a month ago
A i386 GENERIC kernel compiles without the siop, ahc and bha drivers
(will be updated later). i386 IDE/ATAPI and ncr work, as well as
sparc/esp_sbus. alpha should work as well (untested yet).
siop, ahc and bha will be updated once I've updated the branch to current
-current, as well as machine-dependant code.

Update for the NKMEMPAGES changes.

Remove obsoleted macros.

Don't explode when we've got a lot of RAM. Limit our space for buffers
to 1/4 of the kernel VM map.

Pull up to last week's -current.

CL* discarding.

MNN has been standard for a Long Time.

add UBC parameters.

Sync w/ -current.

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.

fix some comments.

MNN is no longer optional, remove dead code

Convert to [pv]addr_t & [pv]size_t.

Define one page free list, and put all pages on it.

Commit to MACHINE_NEW_NONCONFIG.

add new version of non contiguous memory code, written by chuck cranor,
called "MACHINE_NEW_NONCONGIG".  this is required for UVM, the new VM
system (also written by chuck) that is coming soon.  adds new functions:
	vm_page_physload() -- tell the VM system about an area of memory.
	vm_physseg_find() -- returns index in vm_physmem array that this
		address is in.
and several new versions of old functions/macros defined in vm_page.h.


this is the sparc portion.

update comment from 1981 on memory and disk prices -- pr-2754 from Curt Sampson

bring mrg-vm-swap2 onto mainilne.

re-merge mrg-vm-swap into -current, and call it mrg-vm-swap2.

initial work for dynamic swap additions.

Allow larger text (64MB) and data (256MB) segments.
On sun4/sun4c with a virtual address hole (starting at 512MB), this seems
like a reasonable compromise: about 196MB left for shared libs and sysv-style
shared memory segments.
On the sun4m the limits can easily be made larger: consider turning
MAXTSIZ and MAXDSIZ into tunable variables..

Add missing prototypes and fix the fp struct for svr4.

LOCORE -> _LOCORE

Prototype dvma helper functions `dvma_malloc()/dvma_free()'

DVMA space is described by the variables `dvma_start' and `dvma_end'.
Prototype dvma_map*() routines.

#define MACHINE_NONCONTIG here, so all vm_*.c files see it timely.
