Merge tag 'x86-timers-2024-09-17' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 timer updates from Thomas Gleixner:
- Use the topology information of number of packages for making the
decision about TSC trust instead of using the number of online nodes
which is not reflecting the real topology.
- Stop the PIT timer 0 when its not in use as to stop pointless
emulation in the VMM.
- Fix the PIT timer stop sequence for timer 0 so it truly stops both
real hardware and buggy VMM emulations.
