from the sparc64 subtree, which breaks building non-sparc64 platforms
in the event the sparc64 subtree does not exist.
The problem is specific to the module, because non-module builds are
affected by the presence or absence of "device ebus" in the kernel
configuration.

precisely where locking would be needed before adding it, but it
seems uart(4) draws slightly too much attention to have it without
locking for too long.
The lock added is a spinlock that protects access to the underlying
hardware. As a first and obvious stab at this, each method of the
hardware interface grabs the lock. Roughly speaking this serializes
the methods. Exceptions are the probe, attach and detach methods.

o replace magic constants with #defines (e.g. ETHER_ADDR_LEN)
o move mib variables to net.link.ether.bridge with backwards compatible
entries for well-known items maintained under BURN_BRIDGES
o revamp debugging support so it is conditioanlly compiled with BRIDGE_DEBUG
(on currently) and runtime controlled by net.link.ether.bridge.debug
o change timeout to MPSAFE callout
o optimize lookup for common case of two interfaces
o optimize forwarding path to take IFNET lock only when needed
o make boot-time printf dependent on bootverbose
o sundry style changes (ANSI decls, extraneous spaces, etc.)

a problem for command responses since we rarely ever filled the queue.
However, adapter-initiated commands have a much smaller queue and could
tickle this bug. It's possible that this might fix the recently reported
problems with the aac-2120s, though I haven't been able to reproduce the
problem locally.

the description of the data latch registers (they were described as
readonly).
Added some better and worse aliases for standard registers, mostly taken
from the 16950 data sheet. Define deprecated aliases in terms of the
preferred one.
Don't define com_efr in terms of com_fifo. It is unrelated (in a
different bank).
Merged comments to match (put them at the right of the #defines instead
of duplicating them).
Sorted the resulting sections on UART type and register bank. Added a
comment for each bank.
to ns16550.h. The organization of these files was sort of backwards.
The bits in the registers have no driver or bus dependencies but they
but the offsets of the registers in bus space are very bus-dependent.
However, it does no harm to keep the definitions of the register offsets
in ns16550.h provided they are thought of as internal ns*50 offsets.
that has been recorded earlier and overwrite it again later by
reading it directly from the EEPROM again.
Read the MAC address from the PAR0/PAR1 registers instead, which
are autoloaded on reboot.
Tested on AN985, AN983B. According to the datasheets, it should
also work for the AL981 (I don't have such a chip on a card at home)

If we execute 'dhclient -r', dhclient gets already
killed, so there is no need to do it twice. Only do
this if we really have to release some leases.

Also, since the size of struct mcontext changed, adjust

FYI, any change layout/size change to any arch's struct
mcontext will likely need some minor changes in libpthread.

was added to the fast path to support the COM_IIR_RXRDYBUG() case even
when that case is not configured. This increased the relative overhead
of sio input by almost 25% in the worst case and by 2-3% in the usual
case (usually only about 0.2% absolute per port at 115200 bps). The
quick fix is to significantly pessimize only the COM_IIR_RXRDYBUG()
case.
