- * asm, rather than a .S file, because the assembler won't generate
- * the necessary relocation for the LparMap either, unless that symbol
- * is declared in the same source file. Finally, we put the asm in a
- * dummy, attribute-used function, instead of at file scope, because
- * file scope asms don't allow contraints. We want to use the "i"
- * constraints to put sizeof() and offsetof() expressions in there,
- * because including asm/offsets.h in C code then stringifying causes
