d7dbb0862d Deal with NMIs by jumping through the normal trap() code path. 
At the very least, this will dump the machine state. At best,
we get into ddb().

This provides a useful way to regain control using an NMI button
if the cpu decides to spin at a high ipl.

60bff6ed9c Make sure to sign-extend PTEH/PTEL values before writing to the TLBs. 
Make sure to zero-extend PTEH/PTEL values before comparing with TLB entries.
Don't use the two LSBs of CTC when choosing a "random" TLB entry to replace;
seems like these bits are always zero on this CPU.

ce2ec9e63e Add support for the SMsC LAN83C183 PHY, which actually probes as a 
Seeq 84220.

Also add an 84220-specific work-around for some braindamage (at least
in the PHY I'm working with) where the PHY always comes out of reset
isolated, regardless of the previous state of the BMCR_ISO bit. This
happens even if the PHY has address zero, which is contrary to the
part's datasheet...

The work-around is only applied if we notice BMCR_ISO is set when it
should be clear following reset. The fix is to wait 30mS and clear
it manually. (The change doesn't stick if it's cleared sooner than this)

9bcd736b9d Attach sm(4) at superio, instead of the previous isa bus attachment. 
The latter's probe doesn't pick up the ethernet controller, and the
attach function needs to set MIIF_NOISOLATE.
We attach it at superio mainly because they share the same region of
address space, and the ethernet controller's interrupt is routed
through the superio.

94791afd65 No longer use BTLB entries to map the entire address spaces of I/O subsystems, 
since BTLB entries can be scarce and very little of an I/O subsystem normally
needs to be mapped.

Instead, the pmap now allows mappings of I/O space to be entered with
pmap_kenter_pa.  bus_space mappings for small amounts of I/O space (as for
virtually all devices) are made this way, with BTLB entries still used for
large mappings for things like framebuffers.

This has led to more and cleaned-up uses of bus_space(9) and has caused
some autoconf cleanup.  Also, kgdb is now attached and connected before
autoconfiguration, which is much earlier than before.

libc does not call usync_cntl() to unblock things. We have to cleanup
data allocated in the kernel. This is now done through the emulation
specific exit hook

- IRIX initialize some data in the system part of the PRDA: the pid and

complete (PTEs in PTE space will be evicted durint a context switch).

c23fa5a752 Never send more than half a socket buffer of data. This insures that 
we can always keep 2 packets on the wire, no matter what SO_SNDBUF is,
and therefore ACKs will never be delayed unless we run out of data to
transmit.  The problem is quite easy to tickle when the MTU of the
outgoing interface is larger than the socket buffer size (e.g. loopback).

Fix from Charles Hannum.

a7d44c2503 Use separate function pointers for dmamap_sync pre- vs post- operations. 
Change the bus_dmamap_sync() macro to test the ops argument against pre-
and post- constants.  The compiler will optimize out dead code because
of the constants.  Since post- operations are not needed on ARM (except
for ISA bounce buffers), this eliminate a large number of function calls
which are noops, each of which cost at least 6 cycles just in the call
and return overhead (not to mention whatever other useless work the
compiler decides to do in the callee).
