High Precision Event Timer Driver for Linux
-The High Precision Event Timer (HPET) hardware is the future replacement for the 8254 and Real
-Time Clock (RTC) periodic timer functionality. Each HPET can have up two 32 timers. It is possible
-to configure the first two timers as legacy replacements for 8254 and RTC periodic. A specification
-done by INTEL and Microsoft can be found at http://www.intel.com/labs/platcomp/hpet/hpetspec.htm.

-The driver supports detection of HPET driver allocation and initialization of the HPET before the
-driver module_init routine is called. This enables platform code which uses timer 0 or 1 as the
-main timer to intercept HPET initialization. An example of this initialization can be found in
