leo ef6f3f7e25 Move the definition of MSGBUFSIZE up to the machine-arch level if
possible. Pointed out by Bernd Ernesti.

leo 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.

bouyer 6f3bab1f59 Merge scsipi branch in the mainline. This add support for ATAPI devices
(currently only CD-ROM drives on i386). The sys/dev/scsipi system provides 2
busses to which devices can attach (scsibus and atapibus). This needed to
change some include files and structure names in the low level scsi drivers.

jonathan 1f44934407 * Change Sprite MACH_xxx prefix to MIPS_xxx.
* Use standard mips terminology (xxx_KSEG0, xxx_KSEG1) instead of the
  (more meaningful) Sprite names (xxx_CACHED, xxx_UNCACHED).

jonathan 4692a37162 Final changes for configuring MIPS1 and MIPS3 in a single kernel.
* cpuregs.h:
    rename remaining VMMACH_xxx TLB macros to MIPS_TLB_xxx.
    Add compile-time MIPS3-only, compile-time  MIPS1-only, and
    runtime (both) definitions  for number of TLB ASIDs (tlb pids)
    and shift count to extract a TLB pid.

  * locore.h:
    Delete unused vector slot for indexed TLB writes.
    mips1 and mips3 TLBs are different enough that we have
    to break them out at the caller anyway.

  * Add compile-time MIPS3-only andcompile-time  MIPS1-only
    macros to call locore functions directly by name.
    Use the  existing method table only if

  * mips/mips_machdep.c, mips/trap.c, mips/pmap.c, pmax/machdep.c:
    Use MIPS3_ or MIPS1_ specific names for TLB pids in
    mips3 and mips1 specific code paths (e.g., creating the kernel stack
    for process 0).

Add `options MIPS3' to pmax/conf/GENERIC.

jonathan 68863ebd8e More mips1/mips3 changes to cpuregs.h and psl.h:
* cpuregs.h:
  Delete unused VMMACH_ names (e.g., duplicates of PTE bits in  pte.h).
  Change remaining VMMACH_xxx  names to MIPS1_xxx or MIPS3_xx.
  Fold remaining compile-time definitions into a single #ifdef MIPS3.

* Use MIPS1_ names  in locore_r2000.S, mips3_ names in locore_r4000.S

* Garbage-collect MachHitFlushDCache()

* psl.h:
  use MIPS1_, MIPS3_  symbolic names for Cause register bits.
  change  _R3K to MIPS1_,  _R4K to MIPS3. Conditionalize for mips1 only,
  mips3 only, or when both are defined,  use runtime CPUISMIPS3 test.
