3bbb7f7d45 Move pmap_map() function definition to MD headers, as appropriate. It's 
an internal function, and the VM system shouldn't try to prototype it.
(Note that some ports _don't_ prototype it.)

a355d0bc1b Re-implement page reference bit emulation by using the (otherwise unused) 
valid bit. This is faster than the "unmap all" solution that were described
in that Mach paper _and_ it eliminates the need for checking the wired bit.
As a result of this; swapping started working again on vax :-)

b9f1b716f3 Now that all ports have pmap_activate(), and it has an identical interface,

172a9381b6 - Remove the PCB pointer from the pmap structure. Instead, store the 
page {0,1} base and length registers in the pmap structure.  They will
  be loaded in to the PCB when the process's address space is activated
  by way of pmap_activate().
- Remove pmap_pinit() macro; it's now a real function.
- Prototypes for pmap_pinit(), pmap_activate(), pmap_deactivate().

4730a8cbec Bug fixes and cleanup from Chris Demetriou <cgd@pa.dec.com>: 
- fix _C_LABEL so that it actually works.
- make __RENAME use _C_LABEL.
- fix __RENAME so that it expects an unquoted argument.
- fix __indr_reference and __warn_references so that they
  supply their own final semicolon.
- define __warn_references to nothing if not GNU C (required
  by the way it's used).

The __warn_references semicolon change has to be made
so that __warn_references can be defined into nothing.
(A ; all by itself isn't a great idea.)  The __indr_reference
change was made for consistency.

fd48076569 Use genassym for the first time in vax port history. Rewrite cpu_exit,

ae27edc757 Major rewriting, optimization and simplifying of the pmap code: 
- Map in all physical memory first in system space. This reduces
  pmap_copy_page() and pmap_zero_page to 3 resp. 2 instructions.
- Have fized position user page tables. Makes the pv_table smaller
  and all reverse references faster (and simpler).
- Remove the wiring code. Nobody doesn't even know what a DR32 is anymore.
- Simulate page reference bit by setting page invalid, as suggested by
  Rich Draves in a paper for 1991 Mach Usenix Symposium.

This reduced the time spent in the pmap module to between 70-75% of
the previous; and made process startup _much_ faster.

6ab3092b11 Add byte-swapping functions (bswap16, bswap32, bswap64) to libkern. 
Only assembly version for i386 bswap16 and bswap32 for now (bswap64 uses
bswap32). Contribution of assembly versions of these are welcome.
Add byte-swapping of ext2fs metadata for big-endian systems.
Tested on i386 and sparc.

d4713d24c2 Implement the kernel part of pr-1891. This allows for a more flexible sized 
msgbuf. Note that old 'dmesg' and 'syslogd' binaries will continue running,
though old 'dmesg' binaries will output a few bytes of junk at the start of
the buffer, and will miss a few bytes at the end of the buffer.

96acdadef7 First step inn removing config_scan() and the hacks that gave devices 
on indirect-config busses a (permanent) softc that they could share
between 'match' and 'attach' routines:

Define __BROKEN_INDIRECT_CONFIG so that old autoconfiguration
interfaces are used, until drivers are converted to use the new
interfaces (actually, converted back to use the _older_ interfaces)
which prohibit indirect configuration devices from receiving a softc
in their match routine that they can share with their attach routine.

f86410093b Changed name of __weak_reference() to __indr_reference(). They really 
are indirect references, and I want to add a real __weak_reference()
macro to <machine/cdefs.h> soon.

b8403d582b don't be so quick to cast macro arguments to unsigned; if the 
arguments are really off_t's (e.g. to btodb), then you can lose
information.  This was the "> 4G file systems don't work" bug; physio
uses btodb, which was broken.

830a53e394 ANSI says that <stdarg.h>'s va_end macro must expand to a void expression. 
For consistancy, I'm changing <varargs.h> too.

9540190d45 This file, which will be included by <sys/cdefs.h>, will contain macros 
such as __warn_references() and __weak_reference() which are actually
machine dependant.  This will make it easier for ports that are being
bootstraped with ELF and ECOFF based toolchains.

This change also introduces a new macro, _C_LABEL(x).  _C_LABEL expands
its argument, an identifier, to a character string of the identifier
name as it is represented in an object file.

For most ports, _C_LABEL(x) will expand to "_x", for ELF based ports
_C_LABEL(x) will expand to "x".
