Subject: drivers/char/agp/alpha-agp.c: Change return type to vm_fault_t
Use new return type vm_fault_t for fault handler. 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.
Ref-> 1c8f422059ae ("mm: change return type to vm_fault_t") was added in
4.17-rc1 to introduce the new typedef vm_fault_t. Currently we are making
change to all drivers to return vm_fault_t for page fault handlers. As
part of that char/agp driver is also getting changed to return vm_fault_t
type from fault handler.
