applied to tip:timers/hpet, thanks Andreas!
Btw, maybe the HZ_1000 bugfix could be the fix for a weirdness
i'm seeing very rarely on one of my testsystems:
[ 8.850706] bus: 'pci': driver_probe_device: matched device 0000:04:00.0 with driver e1000e
[ 8.850706] bus: 'pci': really_probe: probing driver e1000e with device 0000:04:00.0
[ 177.308165] e1000e 0000:04:00.0: PCI INT A -> GSI 17 (level, low) -> IRQ 17
[ 177.668182] e1000e 0000:04:00.0: setting latency timer to 64
there's almost 3 minutes between those lines printed, although
it should have taken milliseconds!
