mm/hmm: convert to use vm_fault_t
Convert to use vm_fault_t type as return type for fault handler. kbuild reported warning during testing of *mm-create-the-new-vm_fault_t-type.patch* available in below link - https://patchwork.kernel.org/patch/10752741/ kernel/memremap.c:46:34: warning: incorrect type in return expression (different base types) kernel/memremap.c:46:34: expected restricted vm_fault_t kernel/memremap.c:46:34: got int This patch has fixed the warnings and also hmm_devmem_fault() is converted to return vm_fault_t to avoid further warnings.
