Actually, I was thinking about something a lot simpler: something
along the lines of adding the CPUID check in a helper function which
rdt_pseudo_lock_init() calls. If the cache is not inclusive - and my
guess is it would suffice to check any cache but I'd prefer you correct
me on that - you simply return error and rdt_pseudo_lock_init() returns
early without doing any futher init.
How does that sound?
Thx.
