[PATCH 0/7] (Re-)introducing pvops for x86_64 - Consolidation part
Hi folks,
Here is the result of the latest work on the pvops front, after the x86

changed, except for proper vsmp support - which was discussed, but not
implemented before - and the introduction of smp_ops in x86_64, which eased
the merging of the smp header.
