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"
* 'x86-timers-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
x86/tsc: Mark cyc2ns_init() and detect_art() __init
x86/platform/UV: Mark tsc_check_sync as an init function
x86/tsc: Make CONFIG_X86_TSC=n build work again
x86/platform/UV: Add check of TSC state set by UV BIOS
x86/tsc: Provide a means to disable TSC ART
x86/tsc: Drastically reduce the number of firmware bug warnings
x86/tsc: Skip TSC test and error messages if already unstable
x86/tsc: Add option that TSC on Socket 0 being non-zero is valid
x86/timers: Move simple_udelay_calibration() past kvmclock_init()
x86/timers: Make recalibrate_cpu_khz() void
x86/timers: Move the simple udelay calibration to tsc.h
