sys/arch/amd64/amd64: tsc.c
Log message:
Stop promoting the TSC as a high quality timecounter on MULTIPROCESSOR
systems. There is no guarantee that the TSCs on different cores are
synchronized when the OpenBSD kernel boots and we don't have code to
synchronize them ourselves. This affects both AMD and Intel CPUs and
even cores on the same socket can by out of sync.
