This patch set is intended for the next merge window. They are just enhancements of the already merged patches or ia64 porting from x86 paravirt techniques and that their quality is enough for merge. This patch set is for binary patch optimization for paravirt_ops. The binary patch optimization is important on native case because the paravirt_ops overhead can be reduced by converting indirect call into in-place execution or direct call. The patch series does - The first patch imports helper functions which themselves doesn't interesting things. -...

Hi all, I've been working on a port of paravirt_ops for the x86_64 architectures for a couple of days. Here's the result so far. I'm posting it soon for early cooments. The more, the better. It's obviously based on the previous work for i386, with the needed modifications. By now, I'm able to boot a bare metal kernel, but there a...
