- * IA32_TSC_ADJUST test
- *
- * According to the SDM, "if an execution of WRMSR to the
- * IA32_TIME_STAMP_COUNTER MSR adds (or subtracts) value X from the TSC,
- * the logical processor also adds (or subtracts) value X from the
- * IA32_TSC_ADJUST MSR.
- *
- * Note that when L1 doesn't intercept writes to IA32_TSC, a
- * WRMSR(IA32_TSC) from L2 sets L1's TSC value, not L2's perceived TSC
- * value.
- *
- * This test verifies that this unusual case is handled correctly.
