[PATCH] device driver for the SGI system clock, mmtimer

[PATCH] device driver for the SGI system clock, mmtimer

SGI has been using this driver under Linux since 2001 but it was
never included in the upstream kernel. SuSE did include the patch for mmtimer
in SLES 9. The driver has been widely used for applications on the Altix
platform.

The timer hardware was designed around the multimedia timer specification by
Intel but to my knowledge only SGI has implemented that standard. The driver
was written by Jesse Barnes.

The second revision has interrupt support removed and was somewhat simplified
by removing one include file.
