[PATCH RFC V9 0/19] Paravirtualized ticket spinlocks

FWIW I use the paravirt spinlock ops for adding lock elision
to the spinlocks.

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.

It also uses interrupt ops patching, for that it would
be still needed though.
