SMP support for Linux with up to 16 processors using the Intel MP
specification.
-WARNING:
- This is experimental. Back up your disks first. Experience is that
-it is basically stable in its current (inefficient form).
+SMP on x86/Linux is now an official feature and is not exprtimental.
+Experimental SMP support for other architectures is underway.
+
+Please view linux/Documentation/smp for more information about enabling
SMP.

To fix:
o Fix sys_idle to exit/enter kernel state and do hlt's.
-o Fix scheduler decisions to reschedule. Per cpu reschedule ?
-o Clean up message pass.
-o Test for B stepping processors.
-o Clean up processor specific/independent split.
o Document it all. [PARTLY DONE]
o Halt other CPU's on reset/panic doesn't always work.
o Don't waste page at 4K - don't need it now.(watch the GDT code).
-o Dump bootup pages once booted somehow.
o Clean up warnings/volatiles.
o Fix load_TR() for non contiguous processor ids
o Iterate over the slave timer requests if one is lost (keep a count per cpu)
-o Distribute irq's (locking present just needs the 82489 to be asked
- nicely).
o 486 startup code.
o How to handle mixed FPU/non FPU processors.
+o Test IO-APIC on various hardware.
+o Seperate IO-APIC from SMP.
