Hey folks, This is the part-of-pvops-implementation-that-is-not-exactly-a-merge. Neat, uh? This is the majority of the work. The first patch in the series does not really belong here. It was already sent to lkml separetedly before, but I'm including it again, for a very simple reason: Try to test the paravirt patches without it, and you'll fail miserably ;-) (and it was not yet

Here is an slightly updated version of the paravirt_ops patch. If your comments and criticism were welcome before, now it's even more! There are some issues that are _not_ addressed in this revision, and here are the causes: * split debugreg into multiple functions, suggested by Andi: - Me and jsfg agree that introducing more pvops (specially 14!) is not worthwhile. So, although we do
