As noted by Georg Chini, ipt_entry object are of variable size
so just copying individual struct ipt_entry slots around does
not work.

Here's a show-stopper patch for Alpha; missing it prevents several of
our platforms ("white box" 3000 and 5000 series) from booting.

- HAVE_DEC_LOCK depends on SMP
- Trap return preemption check needs interrupt disabled check
- Implement write_trylock
- Fix in_atomic() definition when PREEMPT enabled

Here is the minimal patch that fixes things that do not work and that
can be noticed fairly easily:

        - remove a typo in pfm_check_task_state() which causes
          PFM_READ_PMDS to fail when context is in  PFM_MASKED state.

        - fix a typo in perfmon_mcklinley.h when checking the value
          combinations for when writing to PMC14. This could reject a
          valid request to program PMC14.

This fixes a sleep-in-spinlock bug for binfmt_misc registration.

That lock is purely for the list, not for the dentry.

Only set the rate/resolution if the user actually asked
for it. Some mice and KVM switches don't like to have
their rate forced.

exit_notify() used to leave a window open when a thread
died that made the thread visible as a ZOMBIE even though
the thread reaped itself. This closes that window by marking
the thread DEAD within the tasklist_lock.

Force Device-Mapper to use PAGE_SIZE or smaller I/O when the underlying
device has a bvec_merge_fn routine registered.  This will fix the
situation of Device-Mapper submitting I/Os to RAID-0 that span the
RAID-0 chunk boundaries.

Joe is working on a better solution that actually honors the MD
merge_bvec_fn routine.  But this minimal change will fix the problem for
the time being.

enable on UP-PREEMPT.

Without this, the enable could "migrate" up into the critical
region (on SMP, the actual spinlock would act as an additional
barrier and PREEMPT was ok).

I am still not sure that this change all by itself is enough
to make us accept zero initial timestamps properly.

We updated ip_nat_setup_info to set the initialized flag and call
place_in_hashes, but *didn't* change the call in ip_fw_compat_masq.c
which also calls place_in_hashes() itself (again!).  Result: corrupt
list, and next thing which lands in the same hash bucket goes boom.

Thanks to Andy Polyakov for chasing this down.
