* Time as measured by the TSC may go backwards when resetting the base

* higher than the resolution of the other clock scales. Thus, many
* possible measurments of the TSC correspond to one measurement of any
* other clock, and so a spread of values is possible. This is not a
* problem for the computation of the nanosecond clock; with TSC rates
* around 1GHZ, there can only be a few cycles which correspond to one
* nanosecond value, and any path through this code will inevitably
* take longer than that. However, with the kernel_ns value itself,
* the precision may be much lower, down to HZ granularity. If the
* first sampling of TSC against kernel_ns ends in the low part of the
* range, and the second in the high end of the range, we can get:
*
* (TSC - offset_low) * S + kns_old > (TSC - offset_high) * S + kns_new
*
* As the sampling errors potentially range in the thousands of cycles,
* it is possible such a time value has already been observed by the
* guest. To protect against this, we must compute the system time as
* observed by the guest and ensure the new system time is greater.
