Hi,

I just committed code to impliment simple locks for SMP.  I created a simple
lock (imen_lock) to lock the critical region of "IO APIC & apic_imen" accesses.
I moved the code that accesses these critical regions *outside* of the GL 
(mp_lock).  It seems to work!!!

YMMV, be aware that I will be mucking with other sections of the ISRs
next, so you may want to avoid updates for any "important" systems for
awhile... (ie its time to break things).  But otherwise, please test this
code if you can.
