christos e596968eda - printf -> kprintf, sprintf ksprintf 
- const poisoning for the copy routines.
- fu* su* fixes:
  XXX:
    1. These are poorly named [better names should have real sizes in them]
    2. Not all of them are in use implemented
    3. Interface is broken; no way to detect errors in fu*
    4. The kernel man 9 pages for copy, fetch and store leave a lot to be
       desired.

jtc c5364e6a93 S_ISFIFO(x) should not return true with sockets. S_ISSOCK(x) should

new versions.

gibbs b9c06e6fa3 dev/microcode/aic7xxx/aic7xxx.seq, 
dev/microcode/aic7xxx_seq.h,
dev/ic/aic7xxxreg.h:
  Remove intrinsic knowledge about SDTR and WDTR messages and replace it
  with a generic message system that allows the kernel driver to handle
  SDTR, WDTR and any other type of extended message it chooses too.  This
  makes the sequencer code much simpler, makes extended message handling
  debuggable since the bulk of the work is in the kernel driver, and saves
  lots of instruction space.

  Regen microcode header file.

dev/ic/aic7xxx.c, dev/ic/aic7xxxvar.h:
  Add code to handle WDTR and SDTR negotiation in light of the changes in
  the message interface to the sequencer.  Don't reject targets that
  negotiate async by sending an SDTR with a 0 offset.  Use an sdtr message
  with 0,0 to negotiate async when a target suggests a period that is too
  long for us to handle.  Some tape and cdrom drives don't like us doing
  the message reject that we did in the past.

  Fix a problem with handing the QUEUE FULL condition.

  Fix a race condition (most likely the cause of the SCB paging problems) that
  might allow the sequencer to get unpaused before the condition that caused
  it to be paused (a SEQINT) was handled.

  Race condition pointed out by Doug Ledford <dledford@dialnet.net> and
  by "Dan Willis" <dan@plutotech.com>.

dev/pci/ahc_pci.c:
  Add support for the 2940AU, an aic7860 based controller.

dev/pci/pcidevs.h, dev/pci/pcidevs_data.h:
  Add product IDs for the 2940AU, aic7860 and aic7855.

  Regen data file.

scsi/scsi_message.h:
  Add MSG_EXT_SDTR_LEN and MSG_EXT_WDTR_LEN - the length of bytes in these
  extended messages.

Thanks to Chuck Cranor <chuck@maria.wustl.edu> for testing these changes
out for me.

cgd d557a6a159 change md_coredump struct to actually reflect the machine-dependent stuff

cgd cd3ab82ec2 clean up a comment added in the last commit 1996-10-07 18:29:24 +00:00
cgd 5d4cf83257 when loading interpreter: check its vnode type, check its mount point 
for NOEXEC and NOSUID, and make sure the interpreter file is executable.
The mount point checks are done because, even though the interpreter
is not the program being 'executed', code from the interpreter is being
executed, and so the mount point's flags should be respected.

scottr f8b0c86aa8 The 68LC040 generates a format 4 stack frame for floating point 
exceptions, which puts the address of the instruction we faulted
on in a different location.  Copy it and handle as we normally would,
restoring the saved PC before returning.

The FPE should probably be reworked to take advantage of the 68LC040's
precalculated effective address, at some point.

jonathan fbdaac9a7a Use "MIPS1" and "MIPS3" as preprocessor tokens to select {config,compile}-time 
support for mips-1 (r2000 family) and mips-3 (r4000 family) CPUs.
Avoids inconsistent use of CPU_R2000 and CPU_R3000.

to noioctl().

cgd c11ba5f711 key on ELF_TOOLCHAIN being defined (presumably in /etc/mk.conf) 
to signal that the build is happening on a machine with an ELF
toolchain.  This is temporary, until a better toolchain-recognition
scheme is worked out.

mycroft 767522373b If we get a RXRDY interrupt, but RXRDY is not set in the LSR, briefly set IER 
to 0.  This fixes a condition where some UARTs send an infinite stream of
RXRDY interrupts.

enough functionality to find a VGA card....
Will be expanded when I buy more pci-cards ;-)

thorpej d01962702f General cleanup: 
- make a prototyping sweep
	- do some garbage collection
	- always print the status of enabling memory parity checking
Still some more to do.

thorpej a6a1f78d0c Handle kernel trace traps and breakpoints like the Sun3 port: 
- Only pass user trace traps and breakpoints on to trap().
	  Gets rid of some hair in the trace/breakpoint trap cases.
	- Before entering the debugger, switch to a temporary
	  stack so that the debugger can alter the stack pointer.
	- Add glue for KGDB (still not complete).
Some other minor cleanup:
	- Protect against some bad pointer derefs.
	- Be more a little more verbose when a fatal trap
	  occurs to aid debugging.

thorpej 2793eb282e If console is on an ite, make sure the HIL is initialized enough for 
the keyboard to work.  Fixes a bug where booting with `-d' worked
only on systems using a serial console.

While I'm here, eliminate some redundancy in the ite console intialization
code.
