The problem is not due to our HTT support.

MPACPI first probes the processors from ACPI MADT (detects
cpu0 and cpu1).  After that it gives to configure busses
from the ACPI DSDT since it finds your ACPI BIOS listed on
the acpi_quirks table.  The kernel has to fall back to
MPBIOS but your kernel does not have it enabled  (here the
kernel had to report it and should panic IMHO).  The kernel
misunderstands that it does not yet configured the
processors and falls back to uniprocessor mode (detects cpu2).
