Currently __set_fixmap_offset is a macro function which has a local variable called 'addr'. If a caller passes a 'phys' parameter which is derived from a variable also called 'addr', the local variable will shadow this, and the compiler will complain about the use of an uninitialized variable. To avoid the issue with namespace clashes, 'addr' is prefixed with a liberal sprinkling of underscores. Turning __set_fixmap_offset into a static inline breaks the build for several architectures. Fixing this properly requires updates to a number of architectures to make them agree on the prototype of __set_fixmap (it could be done as a subsequent patch series).
