From: "Mike Rapoport (Microsoft)" <rppt@xxxxxxxxxx>

Several architectures support text patching, but they name the header
files that declare patching functions differently.

Make all such headers consistently named text-patching.h and add an empty
header in asm-generic for architectures that do not support text patching.
