The major changes are:
+ 4Gb (24XX) card support
+ Rewritten fabric and loop evaluation code
+ New f/w sets
The 4Gb changes required major rototilling, which caused a rewrite of
fabric and loop eval code. The latter can now be set up to tune for
dynamic device arrival/departure if the framework is set up for it,
or to be firm about waiting for devices.
Testing has been principally on amd64, i386 and sparc64 and seems to
not have broken things for me.

* Include definitions of adapter-initiated fibs.
* Send aifs back to the adapter after we receive them.
* Use indexes instead of pointers in 32-bit hardware registers.
* If we get a message that there's a printf from the adapter, but we have
a NUL in the first character of the printf string, change the NUL to a
space.
- Make linux_sys_rt_sigreturn() return EJUSTRETURN on success.
- Add missing rax to linux_sigcontext structure; and save/restore
its value like other members in linux_sendsig()/linux_sys_rt_sigreturn().

My SGI issued IBM DORS-32160 will respond to every message with a sync
negotiation (even IDENTIFY) until it gets a response it likes (and it
definitely doesn't like async). Unfortunately, this locks us into an endless
loop after sending IDENTIFY, since the device responds with a SYNC
negotiation that we refuse to accept. This refusal results in a new
target-initiated sync negotiation, and so on...
To work around this, permit negotiating sync mode on an unexpected
target-initiated sync negotiation.
decompress any data, whatever is the radio decompressed data / compressed

It fixes the last issues with fast_ipsec and ipcomp.

Reviewed a long time ago by sam@
buildable state after the yamt-idlelwp merge.
Struct cpu_info now must contain ci_want_resched, so get rid of the
global want_resched.
The cpu_need_resched macro now takes two arguments.
We need to declare proc_trampoline() from for the new m68k vm_machdep.c.
The fields l_back and l_forw no longer exists in struct lwp, so excise
their definition from genassym.cf.
Remove the use of the apparently now obsolete m68k/proc_subr.s.
from proc_trampoline to match the other ports).
A DIAGNOSTIC kernel will now boot and run. LOCKDEBUG still doesn't work yet.
Also, my amiga no longer loses time.
Use return value from cpu_switchto for previous lwp in lwp_trampoline.
Also shamelessly steal a comment from uwe written for sparc that explains
all this.
Thanks to tnn, mrg, and uwe for helping to debug this.
- in lwp_trampoline, oldlwp is already in %o0. don't save or the wrongly
saved copy from cpu_lwp_fork(). as repeatedly pointed out my uwe.
- in cpu_idle use retl not ret. as pointed out by martin.
thanks to uwe/martin/tnn for all the real debugging work.
- use macros to deal with pathnames in userspace, when veriexec is used.
- reorder the veriexec_ call arguments for consistency.
With help from elad@ finding the last bug.
Using movq would copy pcb_flags along as well, which would cause traps
because bad bits would be written into %cr0 a few instructions later.
This wouldn't happen for native NetBSD processes (no pcb_flags set), but
it would happen for Linux processes.
to the beginning so they can still be accessed in assymbly code using 8 bit
offsets. The addition of a big structure in cpu_data moved these outside
the range of the addq instruction. Gas should have complained that the
immediate value was too large, but just silently truncated it. I can now
run multiprocessor again.
Actually, we do need separate "no references in file server" and
"noref + inactive" flags if we wish to correctly support unix open
file semantics and optimize away pre-reclaim cache flushes. So,
add PNODE_DYING which stands for norefs + inactive.

curcpu()->ci_want_resched is now required, so get rid of the
want_resched global. Also, cpu_need_resched() now takes two arguments.
The l_next and l_back fields in struct lwp no longer exists, so delete
references to it from genassym.cf.
Also, m68k/m68k/proc_subr.s is no longer used, says mhitch, so remove its use.
This brings the atari BOOT kernel back to a buildable state.
- don't use void * for pointer arithmetic
- don't try to modify const parameters
A kernel with 'options TCP_SIGNATURE' works as well as it ever did, now.
(ie, clunky, but passable)
the struct tcphdr * argument of tcp_dooptions(). RFC2385 support
(options TCP_SIGNATURE) needs to modify the header during options
processing, and this revision broke it.
OK yamt@.
the kernel it has 0 references to the node in question. In other
words, this can be used to avoid inactive(), or, if the file server
does not implement inactive, prompt reclaim for removed nodes.
as we give a reference to userspace for the puffs_node for the
duration of the poll call. So reference count puffs_node separately
from the parent vnode. vref()/vrele() is not possible due to a possible
surprise visit from VOP_INACTIVE.
called by the MI code.
Implement a way of tracking the vmspace allocated to a process and its
LWPs so that if it changes underneath us we can correct the space id in
the trapframe in pmap_activate for now.
An example of when this happens is vfork/exec.
An exec hook is probably the way to go.
creating a trapframe, with exceptions disabled and using only BANK1
registers. If a valid pte is found, load it and return. Otherwise
create a trapframe and proceed to the full-blown C handler.

idle lwp, and some changes depending on it.
1. separate context switching and thread scheduling.
(cf. gmcgarry_ctxsw)
2. implement idle lwp.
3. clean up related MD/MI interfaces.
4. make scheduler(s) modular.
and other information instead of always using VDIR. To make this
possible without races, require all root node information already

operation completely.
