Subject: [PATCH v2] powerpc: kvm: Change return type to vm_fault_t

Use new return type vm_fault_t for fault handler
in struct vm_operations_struct. For now, this is
just documenting that the function returns a 
VM_FAULT value rather than an errno.  Once all
instances are converted, vm_fault_t will become
a distinct type.

vm_fault_t")
