- Support for setting memory range attributes on SMP systems using the
new SMP rendezvous function
- Don't print the confusing default memory type message.
- Allow legal overlapping range types.
- Turn interrupts back on after setting MTRRs in UP mode (whoops)
- Don't waste time calling invltlb() after wbinvd(); it's not
SMP-compatible (interrupts are off) and unncessary because
wbinvd already flushes the TLB.
This code is now essentially feature-complete.
