If someone has a config where this is set to some non-default value,
won't changing the name cause this to revert back to the defaults?

I don't know how big of a deal it is to other folks, but you can always
do this:

config SPLIT_PTE_PTLOCK_CPUS
  	int
	default SPLIT_PTLOCK_CPUS if SPLIT_PTLOCK_CPUS
