FWIW I use the paravirt spinlock ops for adding lock elision

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.

Hi Andi, IIUC, you are okay with the current approach overall right?
