Some parts are due to corenet versus non-corenet, such as the actual

There's also a two-core assumption in the synchronization code which
I've complained about multiple times -- although on closer inspection it
looks like this is done under cpu_add_remove_lock, and we can assume
that there's only one core at a time in take_timebase(), regardless of
how many cores are in the system.
Right, it should work fine with any number of cores or am I missing
something ? (btw, since when complaining about something helps ? :-)

Cheers,
Ben.
