The ones listed in paravirt.c are CC'd. I am CC'ing all the other
folks related to IA64 listed in MAINTAINERS now.

Just a heads up so the new folks CC'd can get up to speed:
I am proposing moving the steal time calculation to inside the core 
scheduler. This move will make it easier for us to make decisions based 
on steal time accounting on virtual machines. Ia64 KVM may or may not 
follow this route - nothing that already works should break with this 
change.

This patch is needed only to avoid breaking compilation, since it 
introduces two new variables that are expected be present when 
CONFIG_PARAVIRT, to paravirt.c.
