From: Alexey Kardashevskiy <redacted> 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.

This seems a slightly odd place to put the declaration of a function which is defined in the KVM code. kvm-ppc.h might be a better place. Paul.
