KVM: ia64: Define printk function for kvm-intel module
kvm-intel module is relocated to an isolated address space with kernel, so it can't call host kernel's printk for debug purpose. In the module, we implement the printk to output debug info of vmm. Signed-off-by: Xiantao Zhang <xiantao.zhang@intel.com> Signed-off-by: Avi Kivity <avi@redhat.com>
