/* 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/x86/Kconfig.cpu, this just converts
|
|
the CONFIGs into a bitmask */
