There is "softlockup_tick()" function in the source code of linux-2.6.32, but what's the corresponding function name in the linux-4.9 or later?

Hi, list There is "softlockup_tick()" function in the source code of linux-2.6.32(refer to https://elixir.bootlin.com/linux/v2.6.32.39/source/kernel/softlockup.c#L104), but what's the corresponding function in the linux-4.9 or later? There is not even a source code file named by softlockup.c in the linux-4.9 or later? Thank you for your attention to this matter.
