[4.14] Failing selftest timer/adjtick

Hi,

we found that on the selftest timer/adjtick fails on arm64 (tested on
some renesas board and in qemu) quite frequently.
By bisecting the kernel I found that it stopped failing after commit
78b98e3c5a66 (timekeeping/ntp: Determine the multiplier directly from
NTP tick length).
Should this patch be applied to 4.14 and is it even possible or could it
break something else?

Thanks,
Joerg
