Hello,

during system startup the kernel reports detailed information about
the CPU and its features:

cpu0: Intel Pentium III (Coppermine) (686-class), 701.63 MHz
cpu0: I-cache 16K 32b/line 4-way, D-cache 16K 32b/line 2/4-way
cpu0: L2 cache 256K 32b/line 8-way
cpu0: features 383f9ff<FPU,VME,DE,PSE,TSC,MSR,PAE,MCE,CX8,SEP,MTRR>
cpu0: features 383f9ff<PGE,MCA,CMOV,FGPAT,PSE36,MMX,FXSR,XMM>

How can I query this information from an userland program to check if
it can use MMX?

	Kind regards
