From: Alexey Kardashevskiy <aik@ozlabs.ru>
The lookup_linux_pte() function returns a linux PTE which is required to convert KVM guest physical address into host real address in real mode.
This convertion will be used by upcoming support of H_PUT_TCE_INDIRECT as TCE list address comes from the guest directly so it is a guest physical.
