Virtualization - Jan 2008 - [PATCH 0/6] lguest patches for compiling x86_64

Right now, I have lguest in-tree module compiling on x86_64.
It's not yet on a sendable state, since the module itself isn't loading.

However, this subset of the series is pretty straightforward, and I'm
sending it
now aiming at reducing the delta size in the future ;-)

Have fun,

This patch adds the ktime.h header explicitly to hypercalls file,
and avoid depending on it being included somewhere else.
