I think you're trying to get across the point here that the kernel needs
to know about protection keys, have it enabled, and be running on a CPU
with pkey support.

To me "system" is a bit ambiguous here but _can_ refer to the whole
hardware/software system as a whole. To avoid redundancy, I'd say either:

If both the kernel and the processor support protection keys...

or

If the system supports protection keys...

But I'm ok with what you have in any case. Folks will understand what
you're saying:
