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.

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
