efi_stub_entry() and efi_handover_entry() are entered from efi-mixed.S and, through the efi32_stub_entry() and efi64_stub_entry() aliases, by boot loaders using the EFI handover protocol, but have no prototypes. Declare them in x86-stub.h, as asmlinkage, so that the stub can be built with the kernel's -Wmissing-prototypes.
