The unfair lock uses a different jump label and does not require any
special PV ops. There is a separate init function for that.
Yeah, what I mean is that the patches that enable paravirtualization
should also take care of decreasing the unfair-lock jump label when
paravirtualization is enabled.

As there are people who don't like unfair lock at all, I prefer to give
them the option to turn this on or off instead of forcing them to always
use unfair lock in a PV guest.
