it's a more general problem with string constants that are used in
"extern inline" functions etc - they end up in every object that
includes the definitions.
iirc, at least; i noticed this happening with parport.h a while ago.

when I looked if this was a problem for the kernel i only found the
case you're mentioning. You can use someting like this to check that
this isn't happening somewhere else:
objcopy /usr/src/linux/vmlinux /tmp/vmlinux -R .note -R .comment -v -S \
&& strings -n 4 /tmp/vmlinux|sort|uniq -cd|sort -nr|less;rm /tmp/vmlinux
