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.
