Merge tag 'smp-core-2024-07-14' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull CPU hotplug updates from Thomas Gleixner:
"A small set of SMP/CPU hotplug updates:
- Reverse the order of iteration when freezing secondary CPUs for
hibernation.
This avoids that drivers like the Intel uncore performance counter
have to transfer the assignement of handling the per package uncore
events for every CPU in a package, which is a considerable speedup
on larger systems.
- Add a missing destroy_work_on_stack() invocation in
smp_call_on_cpu() to prevent debug objects to emit a false positive
warning when the stack is freed.
- Small cleanups in comments and a str_plural() conversion"
