[    0.000000] tsc: PIT calibration matches HPET. 2 loops
[    0.000000] tsc: Detected 2399.975 MHz processor
[    0.090897] TSC deadline timer enabled
[    1.960034] tsc: Refined TSC clocksource calibration: 2400.007 MHz
[    1.960039] clocksource: tsc: mask: 0xffffffffffffffff max_cycles:
0x22983e30402, max_idle_ns: 440795260848 ns
[    2.959936] clocksource: Switched to clocksource tsc
[   87.168211] Adjusting tsc more than 11% (5941981 vs 7759439)

This is more or less Linus' latest tree (v4.4-rc3 plus some unrelated
platform driver patches).
