314f40f8d8 We can't count on the CIA revision register telling us if we're a 21171

92d17b5b50 clean up the way bootinfo information is passed and used: move the version
number passed by the boot block into a register, change the kernel's
bootinfo handing so that it always uses bootinfo to get bootinfo-ish values
(filling them in if the boot blocks didn't pass them), and make versioning
a small bit more sane.

optimal (really should be done further down the food chain), but we
can't really do that in a nice way right now, and this is much better

VM system was bootstrapped).

e62d894d7a Implement a prefetch spill page for SGMAP DMA. This works around a slight
annoyance on systems that prefetch the next page during memory -> device
DMA if the DMA comes within a certain distance of the end of the current
page.  This could cause machine checks since the PTE after the last page
would not have the valid bit set.

(I'm not going to complain about this slight kludge too much, since prefetch
makes DMA much faster...)

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.

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.

0c2efd7025 Add a "scrollskip" member to wscons_emulfuncs (XXX even though it's not
a function) which specifies how many lines will be skipped when scrolling
up when the bottom of the screen is reached.  Dumb framebuffers skip 10
lines (as before) because the copies are s ... l ... o ... w, but it's
silly to skip 10 lines on VGA, since the copies are much faster, so we
only skip one in that case.

42c325e139 A minor barely acceptable hack to handle having a kernel boot on a system
with large amounts of memory and not spew. This doesn't really replace
fixing this problem better later, but it works for now. Basically, if memory
is greater than 128MB, start upping the sizes of some maps.

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.

87c1a08481 Add stubs for the Alpha Byte/Word Extension (BWX) instructions, present
on EV56 and later processors that have the "amask BWX" bit clear.  These
instructions will be used to implement non-swizzle bus access functions
on newer systems, such as the new AlphaStation 500s with EV56 and 21172
PCI chipsets.
