9c39aaeeca Add common SYSV* options (from i386). 
Add "options LKM", since with ELF/ECOFF format kernels it should now work.

a1cca18262 Implementing bus_space_barrier(9)::isa_bs_barrier() with panic(9) 
does in fact get you a barrier, but it's unnecessarily drastic.

098c344c9b Make sure that we can link against the libsa.a library. It looks like a 
gross hack, but I don't know how to fix this in another way.

05b971dd5f in pmap_pageable(), rather than marking a PT page as not modified 
to trick the pagedaemon into freeing it later, just unmap the page
and free it immediately.  fixes PR 7337.

6f6573cb10 Move BOOTINFO_ADDR up to 0x8001fc00, and reduce the maximum size of a 
bootinfo record to 1kB (we are using less than 200 bytes now) so that it
doesn't run into addition PROM memory.

At 0x8001f00 the bootinfo record was stomping on some memory used by the
SFB cards for font information.

136972df3a Actually, the last change solved a different but related problem than 
the one mentioned in PR 7376.  By clearing the display in iteon()
instead, we can kill both birds with the same stone.

48ff49fee0 When attaching the ite console, clear the entire display rather than assuming 
that the emulator will do it for us.  (The emulator will only clear
full character-sized rows.)  Incidentally fixes PR 7376.

24323d7ef4 In cpu_startup(): 
+ Initialise minaddr to the start of the file I/O buffers.
 + Check for overallocation of RAM for these buffers.
 + Change function name in panic message to match reality.

Code taken from almost every other port, and fixes the:
   uvm_km_suballoc: unable to allocate space in parent map
panic that some people have been experiencing.

869951571d - Clean up ddb_trap() somewhat, and handle exceptions that happen while we're 
in DDB (e.g. if a bad pointer was dereferenced; the debugger will recover).
- Change a comment to indicate that we are on the debugger stack when we get
  to ddb_trap().
- Fix possible buglet in computation of the branch target in db_branch_taken().

701edb8db8 - Revert previous, and do debugger entry if kernel BUGCHK or BPT traps 
happen.  If the debugger doesn't handle the trap, arrange things so the
  debugger won't be called again before we panic.
- Before panic'ing, give the debugger a chance to field the trap, and
  if the debugger has handled things, allow the kernel to continue running,
  like the i386 port does.

a12dedc3ea - Revert previous change to XentIF(), now that we're going to enter the 
debugger differently.
- Pull in debugger glue if DDB is configured.

And one unrelated change, while I was here: Don't create a fake trapframe
for main(); it hasn't been used by main() for quite some time, and panic
if main() returns, because that's not supposed to happen now.

1b2eac076f Add a common debugger entry point, alpha_debug(), which performs various 
tasks (i.e. switches to the debug stack) and then invokes the appropriate
debugger (DDB or eventually KGDB).

902004cefc Don't try and calculate the time in microtime() unless cpu_initclocks() 
has already been called and thus we know the values the timers are using.
This also ensures that clock_sc will always be valid when we try and use
it to read the timer registers.
