[PATCH 0/7] (Re-)introducing pvops for x86_64 - Real pvops work part
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

Hey folks,
Here's a new spin of the pvops64 patch series.
We didn't get that many comments from the last time,
so it should be probably almost ready to get in. Heya!
>From the last version, the most notable changes are:
* consolidation of system.h, merging jeremy's comments about ordering
concerns
* consolidation of smp functions that goes through smp_ops. They're sharing
