Hi all,

I'm upgrading some machines from 4.8-RELEASE to 4.10-RELEASE. The 
machines in question are dual-processor xeon boxes. Now, my boss is 
adamant in that he doesn't want hyperthreading enabled on the machines.

In 4.8-RELEASE things were simple... I just didn't add the "options HTT" 
line to my kernel config file. In 4.10-RELEASE though, HTT is enabled by
default.

So, is there any way to shut off the hyperthreading? I've tried 
disabling it in the BIOS, and had no luck whatsoever.

Thanks,
DMK
