It was removed in v4.9.34-rt24 via 95d4a348841d ("Revert "timers: Don't
wake ktimersoftd on every tick""). I don't see any leftovers or an older
version.
Looking at the queue I see two patches from you and that is:
 timers: Don't wake ktimersoftd on every tick
 tpm_tis: fix stall after iowrite*()s

and the former is reverted. This was v4.9.84-rt62 that I've been looking
at. Could please point me to the code/patches or something?
