Here's a fix for the ppc64 crash during boot.  This corrects the
offending function to use more conventional error codes.  I'll follow up
with return code cleanups for the entire module, and for RTAS code,
since these are probably too big for 2.6.11.

The fix was just trying to hide the real bug, which was in
an old udev script. The change made matters worse.

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.

strcpy is undefined if src and dest overlap.  That's clearly possible
here with a sufficiently deep path on the server.  Use memmove instead.

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.

Good catch.. netem needs to free skb's that are dropped due to loss

Jamal asked me to add back the call to pskb_expand_head before 2.6.11.
This fixes a regression caused by my tc action cleanup patches, the
tc actions most not replace packets, so it must prevent netfilter from
doing so.

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.
