/* Define minimum CPUID feature set for kernel These bits are checked

really early to actually display a visible error message before the

kernel dies. Make sure to assign features to the proper mask!

Some requirements that are not in CPUID yet are also in the
|

CONFIG_X86_MINIMUM_CPU_FAMILY which is checked too.

The real information is in arch/i386/Kconfig.cpu, this just converts

the CONFIGs into a bitmask */
