0179750b00 Correct two more problems of the same type as in rev 1.21: use the length 
of the buffer you're copying from as the loop interator, not the length
of the buffer you're copying to.  Also, rewrite print_single() with
pointer instead of array operators.  Appears to correct some ADB-related
`hangs' during autoconfig.

e6548e54bd Enable interrupts *after* reading the fault address and status. This is 
necessary because some interrupt handlers may cause additional faults (e.g.
through R/M emulation) and thereby trash the previous fault state.

22de25977b Argh, removed last ELF induced problem. We used to have syscall: in locore.s 
and _C_LABEL(syscall) in trap.c. In ELF they are the same. Change the label
in locore.s to be _C_LABEL(_syscall).
While I am there, move the register save and restoral code used in the
*sigcode trampolines into two macros and use them instead of copying 100
lines of assembly each time.
Now everything ELF works.

952f511570 Use -n for ELF. Using -N might work, but produces only one section. 
No flags will not work, because it will produce a kernel loaded at 0xf0000000.
This is because the bfd ELF pagesize (in elf32-sparc.c) is 0x10000. Since
we need to load at 0xf0004000, we use -n.

31c4e50d3a - Change the "savunit[]" and "savirqs[]" arrays to ints, rather than chars. 
The access is more efficient this way (and this was done in the interrupt
  dispatch code, so some cycles are actually shaved), and gcc gets annoyed
  when chars are used as array subscripts.
- Adjust for the fixed Rawhide console initialization.
- When mapping a PCI interrupt, don't always map device 1 to IRQ 16.  Device
  1 is only the internal 53c810 on MID 5, and is an invalid device number
  on any other MID.
- Adjust for change mcpcia_config/mcpcia_softc structures.
- Nuke the kludgy linked list of mcpcia_softc structures.  Instead, just
  use savunit[v] to index into mcpcia_cd.cd_devs[] to find the MCPCIA
  which has the stray interrupt.

- Rename mcpcia_init() to mcpcia_init0(), and make it take a "mallocsafe"
  argument.
- Implement a new mcpcia_init(), which looks for the MCPCIA which has the
  EISA bridge attached.  Initialize this MCPCIA as the console MCPCIA (the
  console on the Rawhide is only allowed on this MCPCIA; firmware rule).
- Eliminate the kludgy linked listed of mcpcia_softcs.  Just use mcpcia_cd
  to find all configured instances.

Separate bug fix: Actually clear the MCPCIA error mask after probing for
PCI (and ISA) devices, don't just clear it twice in mcpcia_init0().

Some other slight cleanup.

9af474a62c - Add a comment explaining why we probe for MCPCIAs in the shuffled 
MID order.
- Export the shuffled MID order; other files now need it.
- Don't derive the GID from the unit number of the mcbus.  A user could
  render his kernel non-bootable by using a different unit number in the
  kernel config file.  We (and the hardware) only support one MCBUS, so
  simply use instance 0.  Note that this will need to be adjusted if there
  are even any multiple-MCBUS systems.

1287bb8599 Always call the platform's cons_init routine (note, it may not do anything, 
but it's a very handy place to put console-related debugging code in,
even if we're still using the PROM console).

02aa04c89e Massive cleanup of the AlphaServer 4100 console initialization code. 
Instead of using the PROM console until autoconfiguration is complete (at
which time we called dec_kn300_cons_init() directly!), make this work like
basically all of the other systems which have PCI attached consoles.  That
is, initialize the PCI chipset which holds the console early, and perform
console initialization at the correct time.

This should make both PCI and ISA display consoles with PC keyboards work
(i.e. the deskside workstation version of the Rawhide).

0df038ccb1 - Use the CTB_TURBOSLOT_* macros from rpb.h. 
- Don't assume bus/slot == ISA display.  Instead, test for TYPE_ISA.
- Some cosmetic (whitespace, mostly) cleanup.

f03f59a5b8 Back out the change to swap Lev1map on MP systems that use the PROM console. 
Basically, we have to completely nuke the _PMAP_USES_PROM_CONSOLE code from
orbit before MP is going to properly work.
