Merge branch 'x86-timers-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 timer updates from Thomas Gleixner:
"These updates are related to TSC handling:
- Support platforms which have synchronized TSCs but the boot CPU has
a non zero TSC_ADJUST value, which is considered a firmware bug on
normal systems.
This applies to HPE/SGI UV platforms where the platform firmware
uses TSC_ADJUST to ensure TSC synchronization across a huge number
of sockets, but due to power on timings the boot CPU cannot be
guaranteed to have a zero TSC_ADJUST register value.
- Fix the ordering of udelay calibration and kvmclock_init()
- Cleanup the udelay and calibration code"
