For Red Hat Linux 7.1 and 7.2, administrators should first upgrade the
kernel to the latest errata package.1 They can then enable
Hyper-Threading by passing the acpismp=force flag through the boot
loader. To determine whether Hyper-Threading is enabled under Linux,
check /proc/cpuinfo; it should show twice the number of physical CPUs in
the server.
