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

This is hopefully the last iteration of the pvops64 patch. >From the last version, we have only one change, which is include/asm-x86_64/processor.h: There were still one survivor in raw asm. Also, git screwed me up for some reason, and the 25th patch was missing the new files, paravirt.{c,h}. (although I do remember having git-add'ed it, but who knows...) Andrew, could you please push it
