[PATCH] x86_64: Fix collision between pmtimer and pit/hpet
On systems that do not support the HPET legacy functions (basically the IBM
x460, but there could be others), in time_init() we accidentally fall into a
PM timer conditional and set the vxtime_hz value to the PM timer's frequency.
We then use this value with the HPET for timekeeping.
This patch (which mimics the behavior in time_init_gtod) corrects the
collision.
