[PATCH] Export three symbols for kvm use.

["Zhang, Xiantao" <xiantao.zhang@xxxxxxxxx>]

Hi Tony,
	In order to build kvm source successfully, we need to export
three symbols for kvm use. Please review. Maybe Avi can check-in to
kvm.git upstream first. 

Thanks
Xiantao

Subject: [PATCH] ia64: Export three symbols for module use

Since kvm/module needs to use some unexported functions in kernel,
so export them with this patch.
