[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

[PATCH 0/15] adjust pvops to accomodate its x86_64 variant
Hi folks,
With this series, the bulk of the work of pvops64 is done.
Here, I integrate most of the paravirt.c and paravirt.h files, making
them applicable to both architectures.
CONFIG_PARAVIRT is _not_ present yet. Basically, this code is missing page
table integration (patches currently being worked on by Jeremy).
Enjoy
