SMP with HTT disabled

[Singh, Vijay]

Hello, I am trying to disable HTT to run some tests. From dmesg I have:
 
CPU: Intel(R) Xeon(TM) CPU 2.66GHz (2666.77-MHz 686-class CPU)
  Origin = "GenuineIntel"  Id = 0xf29  Stepping = 9
 
Features=0xbfebfbff<FPU,VME,DE,PSE,TSC,MSR,PAE,MCE,CX8,APIC,SEP,MTRR,PGE
,MCA,CMOV,PAT,PSE36,CLFLUSH,DTS,ACPI,MMX,FXSR,SSE,S
SE2,SS,HTT,TM,PBE>
  Hyperthreading: 2 logical CPUs
real memory  = 1073676288 (1023 MB)
avail memory = 1041121280 (992 MB)
ACPI APIC Table: <A M I  OEMAPIC >
FreeBSD/SMP: Multiprocessor System Detected: 2 CPUs
 cpu0 (BSP): APIC ID:  0
 cpu1 (AP): APIC ID:  1

# cat /boot/loader.conf
machdep.hlt_logical_cpus=1
 
And mptable output is below. It seems to me that the kernel does not
bring up the 2nd physical CPU. Am I right or wrong.
