[Michael S. Tsirkin]

Looks like the HPET spec at intel.com got moved.
Update the link.

 Each HPET has one fixed-rate counter (at 10+ MHz, hence "High Precision")
 and up to 32 comparators.  Normally three or more comparators are provided,

Either we remove that link completely or we store that document at some stable
URL on kernel.org and be done with it.

I prefer to remove it. 

  1) It's just a bad example of hardware design by committee and we really do
     not need to promote it.
 
  2) Finding that spec if you really have to is not rocket science either.
