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

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.

Use this to simplify 'finish_task_switch', but perhaps more
importantly we can use this to track down why some processes
seem to sometimes not die properly even after having been
marked as ZOMBIE. The "task->state" flags are too fluid to 
allow that well.

This fixes the generic __div64_32() to correctly handle divisions by
large 32-bit values (as used by nanosleep() and friends, for example).

It's a simple bit-at-a-time implementation with a reduction of the high
32-bits handled manually.  Architectures that can do 64/32-bit divisions
in hardware should implement their own more efficient versions.

 - add 'sched_clock'
 - delete smplock.h

The most important part is that it makes x86-64 compile again.
Without that 2.6 users won't be very happy.

It also works around a bug that allowed every user program to reboot the
system on B stepping K8.

Also update to match some recent i386 fixes.

Full ChangeLog:
 - Add acpi_pic_set_level_irq to make ACPI compile again
 - Work around compat mode K8 bug in IRET exception handling
 - Increase exception stack. The old 1k stack was too easy
   to overflow (from Jim Paradis, changed by me)
 - Replace safe_smp_processor_id with cpuid (needed for above)
 - When there is only one node always enable fake_node mode
 - Merge with i386 (NTP gettimeofday monoticity fix, irq nr_vectors change)
 - Fix compile problem for UP kernels in time/cpufreq
 - Set all nodes online at bootup
 - Define node_to_cpumask correctly

This documents the existence of a forth 'motioneye' camera plugged into
the USB bus, of course unsupported by the meye driver.
