Commit 53fafdbb8b21 ("KVM: x86: switch KVMCLOCK base to monotonic raw clock") did so only for 64-bit hosts, by capturing the boot offset from within the existing clocksource notifier update_pvclock_gtod().
That notifier was added in commit 16e8d74d2da9 ("KVM: x86: notifier for clocksource changes") but only on x86_64, because its original purpose was just to disable the "master clock" mode which is only supported on x86_64.
Now that the notifier is used for more than disabling master clock mode, (well, OK, more than a decade later but clocks are hard), enable it for the 32-bit build too so that get_kvmclock_base_ns() can be unaffected by NTP sync on 32-bit too.
