errors for the attachment process for the floppy controller. This is
a band-aide because it doesn't try any of the fallback methods when
_FDE isn't long enough, but should be sufficient for people
experiencing the dreaded mutex not initialized panic.
not sure yet about 5.x... MFC if needed.
Also fixes small problems with examining some registers and
some specific gdb transfer problems.
As the patch says:
This is not a pretty patch and only meant as a temporary
fix until a better solution is committed.

it travels through the IP stack. This wasn't much of a problem because IP
source routing is disabled by default but when enabled together with SMP and
preemption it would have very likely cross-corrupted the IP options in transit.
The IP source route options of a packet are now stored in a mtag instead of the
global variable.
and which takes a M_WAITOK/M_NOWAIT flag argument.
Add compatibility isa_dmainit() macro which whines loudly if
isa_dma_init() fails.

This adds a safebelt that prevents users to mark more than
one "active" partitions, which will lead to a unbootable
machine, especially in multi-boot configurations.

complete backout as the ntpd_sync_on_start etc/rc.conf tunable is still
present, though the default is now NO (was YES). Since we're no longer
syncing time at startup by default when ntpd is enabled (as was the case
24hrs ago), remove UPDATING entry pointing out that ntpd(1) -g is slower
than ntpdate(1).
Hopefully ntpd_sync_on_start="YES" can be made the default for -CURRENT
after 5.3 is cut. At the very least, this should be set to YES when a
user requests to have ntpd enabled via sysinstall(1).

problems:
1) Add locking for SMP, code provided by Alan Cox
2) While testing Alan's patches, I observed serious problems with
the jumbo buffer allocation code (machine crashed twice), so I gutted
it and rewrote the receive handler to use multiple chained descriptors.
Each RX descriptor gets a single 2K cluster, and the chip will fill in
as many as it needs to hold the complete packet.
User reports that this corrects the data corruption issues previously
observed and discussed on -current.
Note that this driver still needs to be hit with the busdma stick.
I intend to inflict said beating in the near future.

careful with the skip condition this time. Addresses are only not taken into
account if:
- The interface is POINTTOPOINT
- There is no route installed for the address
- The user specified noalias (:0)
and - We are looking at an IPv4 address.
This should be enough paranoia to not cause any false positives.
