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.

don't buck the trend and move the call to initmsgbuf() to cpu_startup()

in one go. (This means that the CSRG copyright will no longer be in
the kernel logs).

NOTE: due to hardware requirement of the AGA chipset, the framebuffer width

of 832 bits, which the current X server can't handle.  To get a usable
display, the width needs to be 832 or 768.

0d05b5c280 Use the buffer length passed as a parameter to vmapbuf() and vunmapbuf() 
instead of bp->b_bcount.  The I/O operation may have changed bp->b_bcount,
and not all of the kernel virtual memory will be freed.  This will result
in the VM system putting pages back on the free list which are still
mapped.   This may cause a deadlock later trying to enter pages into
the kernel pmap.  [See PR#4120 for more details.]

d1fbc82e28 From page 6-9 of "Alpha AXP Architecture Reference Manual, Second Edition": 
An IMB intruction must be executed after software or I/O devices
	write into the instruction stream or modify the instruction
	stream virtual address mapping, and before the new value is
	fetched as an instruction.

We were missing calls to IMB after mappings were changed, which caused
systems with large I-caches (e.g. my AlphaStation 500) to fail miserably
when mapping in new pages of program text, or when context switching
(I couldn't even get the shell from init!).

37b8edbeac In addition to MAS_ABT, check TAR_ABT when doing configuration space 
reads.  This is necessary because of newer AlphaStation firmware doing
the Wrong Thing with target aborts behind PCI-PCI bridges, much like they
do the Wrong Thing with master aborts.  Reported by Matthias Drochner.

f784e8dc15 Apparently, new AlphaStation 500/600 firmware has the same problem with 
PCI master aborts as eb164 firmware, so use the same workaround mechanism
on all system types (clear error register's master abort bit, and check
it after accessing configuration space), not just eb164's.

This also fixes a bug on eb164's - when making the Alpha port compile
again, I made an error that caused this to not be used on eb164 systems,
either.  Thanks to Matt Jacob for pointing out this goof.

a little rough around the edges.  Known problems:

- Error recovery could be improved a bit.
- Back traces don't work.
- Single-stepping can be flaky, at times.  (Alpha doesn't have hardware
  support for single-stepping, and I'm not entirely convinced the
  MI DDB software-emulated single-stepping logic is 100% correct.)
- Logic for when to drop into DDB needs some improvement.

8b6e894364 Clean this up a bit; defopt has rendered the #undef hacks unnecessary. 
Also, put the cpu_decl()s in cpuconf.h, so that platform support files
can pull in the prototypes from there, and pull in options for those
systems for which there is code in the source tree.

the *_bus_{io,mem}_init() functions.
