Thomas Gleixner a36f513681 x86/tsc: Sync test only for the first cpu in a package ... If the TSC_ADJUST MSR is available all CPUs in a package are forced to the same value. So TSCs cannot be out of sync when the first CPU in the package was in sync. That allows to skip the sync test for all CPUs except the first starting CPU in a package.
