Please spell out architectures. Changelogs are not space constraint.

Also this sentence does not make sense as it might suggests that
architectures with a fixed compile time known clocksource have something
named timebase. Something like this is more clear:

Some architectures have a fixed clocksource which is known at compile
time and cannot be replaced or disabled at runtime, e.g. timebase on
PowerPC. For such cases the clock mode check in the VDSO code is
pointless.

Hmm?

Thanks,
