mike.travis@hpe.com 97d21003df x86/platform/UV: Add check of TSC state set by UV BIOS ... Insert a check early in UV system startup that checks whether BIOS was able to obtain satisfactory TSC Sync stability. If not, it usually is caused by an error in the external TSC clock generation source. In this case the best fallback is to use the builtin hardware RTC as the kernel will not be able to set an accurate TSC sync either.
