[PATCH] x86-64: Fix HPET timer on x460
[description from AK]
The IBM Summit 3 chipset doesn't implement the HPET timer replacement
option. Since the current Linux code relies on it use a mixed mode with
both PIT for the interrupt and HPET counters for the time keeping. That
was already implemented, but didn't work properly because it was still
using the last interrupt offset in HPET. This resulted in x460 not
booting. Fix this up by using the free running HPET counter.
Shouldn't affect any other machine because they either use full HPET mode
or no HPET at all.
TBD needs a similar 32bit fix.
