- * x86 CPUID access device
- *
- * This device is accessed by lseek() to the appropriate CPUID level
- * and then read in chunks of 16 bytes.  A larger size means multiple
- * reads of consecutive levels.
- *
- * This driver uses /dev/cpu/%d/cpuid where %d is the minor number, and on
- * an SMP box will direct the access to CPU %d.
