    Subjectht CPU flag
    Hello dear developers!

    Here is my system configuration.

    Linux ns 2.6.19-gentoo-r5 #5 SMP Thu May 3 00:45:12 AMST 2007 i686
    Intel(R) Pentium(R) D CPU 3.00GHz GenuineIntel GNU/Linux

    I have Pentium D CPU, which many Windows utilities like cpuz, wcpuid,
    everest identify as D 930 (Dual Core, 3GHz). From Intel site I find out
    that it has no HT feature, nor Windows XP identify it as HT.

    Why do I have "ht" flag in cpuinfo?
    -----------------------------------

    cat /proc/cpuinfo

    So, how must I choose kernel settings like:

    number of CPU's?
    HT support?

    Best regards, Eugene.
