Commit d3b41b6bb49e ("m68k: Dispatch nvram_ops calls to Atari
or Mac functions") causes a number of compile time warnings
to be generated if compiling for a ColdFire MMU enabled target:
In file included from ./arch/m68k/include/asm/atarihw.h:25:0,
from arch/m68k/kernel/setup_mm.c:41,
from arch/m68k/kernel/setup.c:3:
./arch/m68k/include/asm/raw_io.h:39:0: warning: "__raw_readb" redefined
#define __raw_readb in_8
^
In file included from ./arch/m68k/include/asm/io.h:6:0,
from arch/m68k/kernel/setup_mm.c:36,
from arch/m68k/kernel/setup.c:3:
./arch/m68k/include/asm/io_no.h:16:0: note: this is the location of the previous definition
#define __raw_readb(addr) \
^
...
The most strait forward fix is to conditionaly include only
those headers actually required, and to only check for
machine types that are configured/enabled into this build.
