71ad30d0e9 (1) set scsi_link channel to either the appropriate channel (if a

    function, and kill any locally-defined print function.

5c7192b20c Including user-land headers in kernel code is not allowed in NetBSD. 
Therefore:
	(1) define offsetof here, and

	    assertion-checking macros.

bdbfa48c0b Add machine-independent assertion-checking support. macros are: 
assert()	which always does assertion checking
			unless "NDEBUG" is defined.

	KASSERT()	which does assertion checking if DIAGNOSTIC
			is defined.

	KDASSERT()	which does assertion checking if DEBUG is
			define.  This macro exists for compatibility
			with existing ports' assertion checking macros.
			(Assertion checking is not typically an
			"expensive" operation, and DIAGNOSTIC should be
			used for inexpensive consistency checks.)

7b8910c01d Vastly simplified the FPE stubs code now that there are labels for all the 
core entry points. i.e. the linker does the work rather than the stub code.
Optimised transferring the trapframe between UND32 and SVC32 mode stacks
in the fpe_post_proc handler.
Added experimental code to handle must of userret in UND32 mode. This means
that the copy of the trapframe and the switch to SVC32 mode is only needed
if mi_switch() has to be called. (This saves a vast number of pointless
trapframe copies).

Fix so that resource wait queueing works.
Changed all functions to take a pointer to uba_softc instead of unit
number, except for ubareset(). This must be done later.

15f9c59baf check in the code used to build the kernel that Andrew Gallatin used to 
figure out the correct IRQ for the ethernet on the AlphaStation 500.
That code is enabled via KN20AA_BOGUS_IRQ_FROB (but hopefully won't be
needed any time soon, and won't link w/o slight changes to other code).
Basically, when establishing an interrupt that we don't know what to
do with, prompt the user for what interrupt line to enable.  If you
get stray interrupts when you try to use the device (but not before),
then you've got the right line.

b4bfcf063f 21040 ethernet chip on AlphaStation 500 lives in slot 6 (a slot not

Thanks to Andrew Gallatin for booting a test kernel 32 times (trying
each interrupt line, looking for the right one) to find this.

a9ef8aef84 This fixes a nasty little bug where traceroute (and other raw-ip sending 
programs which attach their own header) can crash the machine.  The problem
in this case was:
	a variable "space" was set to the total data to copy,
	len was used to remember how much to copy in this chunk (mbuf),
	in one case, len = min(MCLBYTES - max_hdr, resid) but
		size -= MCLBYTES;
	 instead of
		size -= len;

Note that userland programs can still crash the machine by providing
bogus data in the ip->ip_len field I suspect.  I haven't verified this,
but will soon be doing so and applying a fix of some sort.  Probably
clamping the ip->ip_len value to the true packet size will be ok.
