2100183aff For the CP0 status register bit definitions- add the MX, PX and NMI bits 
and rename TLB_SHUTDOWN and SOFT_RESET to TS and SR (the abbreviations
in the MIPS documentation).

XXX: this file really needs to be cleaned up one day...

aa39671913 Setting chipmem_start and chipmem_end to the same value (size of chip 
memory) greatly confuses the chip memory allocator and can prevent
some systems from even starting the kernel.  Remove the initialization
of chipmem_start (it's initialized in locore.s).

files to follow.

587856dfdd Make the code that matches boot devices much more flexible so it handles 
device classes as well as funny names for matching.  This should allow
us to properly recognize we're booted from a SCSI disk on a PCI controller.

f4e42e7eb6 Add an extremely rough SMBus handler and RTC driver. This will be 
cleaned up significantly when we have an MI SMBus framework, but at
least we can see the RTC on the swarm now.

a1572a6b96 Match all possible CPUs, but print warnings that the processors after 
the first are offline due to the lack of SMP support in the kernel.

9cc65a96d0 3 ports are now using the reciprocal count divisor code now, move it 
to <mips/cpu.h>, and add MIPS_SET_CI_RECIPRICAL and MIPS_COUNT_TO_MHZ
macros to use it.

was already fixed by nathanw, had I bothered to check.

e0b7d8c222 Now make a machine/ directory with symlinks to a small number 
of machine-specific headers.  When ${MACHINE} is sun2, this
allows building the sun3 and sun3x parts of libsa, which need
things like <machine/param3.h> and <machine/param3x.h> to be
#includeable.

d2b9876081 move initialization of the "struct pglist" returned by uvm_pglistalloc() 
from the calling code into uvm_pglistalloc() itself for consistency
and easier error handling

06de426449 SIMPLEQ rototill: 
- implement SIMPLEQ_REMOVE(head, elm, type, field).  whilst it's O(n),
  this mirrors the functionality of SLIST_REMOVE() (the other
  singly-linked list type) and FreeBSD's STAILQ_REMOVE()
- remove the unnecessary elm arg from SIMPLEQ_REMOVE_HEAD().
  this mirrors the functionality of SLIST_REMOVE_HEAD() (the other
  singly-linked list type) and FreeBSD's STAILQ_REMOVE_HEAD()
- remove notes about SIMPLEQ not supporting arbitrary element removal
- use SIMPLEQ_FOREACH() instead of home-grown for loops
- use SIMPLEQ_EMPTY() appropriately
- use SIMPLEQ_*() instead of accessing sqh_first,sqh_last,sqe_next directly
- reorder manual page; be consistent about how the types are listed
- other minor cleanups

b3dd6235ca Since we don't have a wsmouse attachment for the ARM7500 PS/2 mouse, turn 
on the pre-wscons device for it instead.  This allows X to work on my NC.

40a8771d1e Using -N (OMAGIC) when linking the kernel seems to avoid BtNetBSD's doing 
stupid things when loading it on an NC, so do that.  Fixing (or replacing)
BtNetBSD would be better, of course.

e8aaf3c28b Stop using the _MIPS_BSD_API_LP32_64CLEAN ABI. This causes a few problems

341ed8c0d3 Use CPU_MIPS_USE_WAIT and CPU_MIPS_NO_WAIT in the CPU table, and use

5b5cc1ebb8 Add two new cpu capability flags: CPU_MIPS_USE_WAIT for CPUs that use a 
"wait" instruction based cpu_idle(), and CPU_MIPS_NO_WAIT for specific
CPUs that don't use this (applicable to mips32/64 mainly).
