We can't keep reverting these changes, so instead move forward. Most
architectures now have <asm/asm-protoypes.h> and only 3 were left:
- alpha: Added <asm/asm-protoypes.h> and submitted patch upstream
- m68k: Did same, but realised it's only needed for Coldfire configs
so we don't need any patches
- sparc: Cherry-picked changes from upstream
