HTT on 4.10 not working

[robg]

Hi:

Could someone tell me how to get hyperthreading on 4.10 working
correctly? I have a P4 2.8GHz w/ HT enabled and `dmesg` shows:

CPU: Intel(R) Pentium(R) 4 CPU 2.80GHz (2795.24-MHz 686-class CPU)
  Origin = "GenuineIntel"  Id = 0xf33  Stepping = 3

Preloaded elf kernel "kernel" at 0xc0556000.

but running `top` shows

last pid:  7301;  load averages:  0.00,  0.00,  0.00

so I don't think its being used, could someone tell me how to get it
working in 4.10?

Thank you
