We presently deadlock in low-latency mode because the receive code holds
port.lock while calling into the tty code to perform echoing.  The tty code
calls back into the driver, which then takes port.lock.

Fix that by dropping the lock around the echo call.

Frank Fricke reported that hostfs does not verify that a chmod +s, for
instance, is done by a sufficiently privileged user, as long as the UML
kernel itself can complete the operation on the host.

So, for instance, if UML is run as root and under /mnt/host we have a hostfs
mount, this works successfully:

paolo@zion:~ (0)$ chmod 4755 /mnt/host/bin/bash
paolo@zion:~ (0)$ ll /mnt/host/bin/bash

 -rwsr-xr-x  1 root root 662724 2004-10-20 02:15 /mnt/host/bin/bash*

(bash refuses running as setuid, but you could have another shell on the
host, as dash or whatever).

In general, if UML is run as uid 500 on the host, a hostfs mount is done
and under the hostfs mount there is a file with uid 500 on the host, I can
freely make it setuid (if it's executable).

This is especially bad when UML is run as root (which you should not do),
but is a problem in general, since it allows any user to create setuid 500
(in this example) executables on the host filesystem.

Finally, while I was looking at the chmod() implementation, I spotted a
kludge in the code and explained it with a comment.

When a task is put to sleep, it is dequeued from the runqueue while it is
still running.  The problem is that one some arches that have non-atomic

mousedev_packet() clears list->ready too early when called with
"tail == head - 1".  The effect is that the last mouse event from the
hardware isn't reported to userspace until another hardware mouse
event arrives.  This can make the left mouse button get stuck when
tapping on a touchpad.  When this happens, the butten doesn't unstick
until you interact with the touchpad again.

As 'i' and 'host->id' are of different types (signed vs. unsigned),
we need a cast.

Eventually host->id should probably be made unsigned, but this
requires further analysis.

NLMSG_GOODSIZE specifies a good default size for the skb tailroom
used in netlink messages when the size is unknown at the time of
the allocation.

The current value doesn't make much sense anymore because
skb_shared_info isn't taken into account which means that
depending on the architecture NLMSG_GOOSIZE can exceed PAGE_SIZE
resulting in a waste of almost a complete page.

Using SKB_MAXORDER solves this potential leak at the cost of
slightly smaller but safer sizes for some architectures.

another patch which I think should go in 2.6.11, it fixes a crash
when unloading, then reloading iptable_nat.

ip_nat_core doesn't clear the status bits in struct ip_conntrack on
module unload, but zeroes out the nat area. When the module is loaded
again and a connection times out ip_nat_cleanup_conntrack tries to
list_del the zeroed list-head and crashes. There are probably more
conditions under which it can crash or cause other misbehaviour.

Patch from Nicolas Pitre

A more elegant solution could be applied which would require more work.
However there is only one platform using both chips (Lubbock) and half
of the SA1111 features are unusable due to botched DMA support at the
PCB level anyway.  Therefore this solution should be sufficient for
now.
Also removed the SADIV defines which use would not constitute good
programming practice. Divisors should be computed directly in the code
especially since different PXA2xx versions have different clock source
frequencies.  No in-tree driver uses them so this is low impact..
Finally changed alignment to fit rest of file.
