o Do not parse the MADT as a side-effect in AcpiOsGetRootPointer,

   do it as a side-effect of probing for MP hardware. This allows
   us to scan for local SAPICs early (especially before MBUF
   initialization).
o  Fix the Local SAPIC structure so that matches the Local SAPIC
   table entry. Now that the Local SAPIC info is the same as the
   Local APIC info, stop dumping the Local APIC entries.
o  For every Local SAPIC entry in the MADT that's not disabled,
   let the SMP code know about it. They represent actual CPUs.
o  Register the OS_BOOT_RENDEZ entry point and provide a (bogus)
   implementation for the entry point.
o  Provide a mapping for internal IPI numbers to ExtINT vectors.
o  In a MP system, announce the CPUs and start them by sending
   IPI_AP_WAKEUP to each of them. Not that it makes a difference
   at this time :-)
o  Miscellaneous style fixes and other adjustments.
