Merge tag 'smp-core-2024-03-10' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull cpu core updates from Thomas Gleixner:
"A small boring set of cleanups for the SMP and CPU hotplug code"
* tag 'smp-core-2024-03-10' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
cpu: Remove stray semicolon
smp: Make __smp_processor_id() 0-argument macro
cpu: Mark cpu_possible_mask as __ro_after_init
kernel/cpu: Convert snprintf() to sysfs_emit()
cpu/hotplug: Delete an extraneous kernel-doc description
