- If an iptables rule is using --ulog-nlgroup with a
value greated than 4, we crash
- Remove a memory leak when someone throws packets at
the ulog netlink socket

requested, also fix a possible race with two processes using the same
file descriptor.

Misc. kernel preemption-related bits.  Specifically,

 - update to Documentation/preempt-locking.txt (me)

 - preempt-safe arch/i386/kernel/ioport.c :: sys_ioperm()
   (George Anzinger)

 - remove "kernel_lock()" cruft in include/linux/smp.h
   (Andrew Morton)

 - we have a debug check in preempt_schedule that, even
   on detecting a schedule with irqs disabled, still goes
   ahead and reschedules.  We should return. (me)

 - preempt-safe net/core/dev.c :: netif_rx() (George Anzinger)

The raid5 xor checksums use MMX/SSE state and are not preempt-safe.

Attached patch disables preemption in FPU_SAVE and XMMS_SAVE and
restores it in FPU_RESTORE and XMMS_RESTORE - preventing preemption
while in fp mode.

Neither lockd nor rpciod properly drop the BKL on exit.

Yes, the BKL is automatically relinquished on schedule but the failure
to drop the lock throws off the atomic accounting and results in a
preempt_count warning on exit.

This makes them play fair - it does not hurt.
