[patch] kernel_flag is not needed on UP+preempt

[Robert Love]

There is no reason to define and declare the actual kernel_flag spinlock
on UP systems, even if kernel preemption is enabled.

Preempt needs to use the lock_kernel() calls, but it does not need the
actual lock to exist.

So change the check from SMP || PREEMPT to just SMP.  Tests fine.  Patch
is against 2.5.60.
