FWIW I use the paravirt spinlock ops for adding lock elision

Does lock elision still use the ticketlock algorithm/structure, or are
they different?  If they're still basically ticketlocks, then it seems
to me that they're complimentary - hle handles the fastpath, and pv the
slowpath.

This needs to be done at the top level (so the level you're removing)

However I don't like the pv mechanism very much and would 
be fine with using an static key hook in the main path
like I do for all the other lock types.

Right.
