The old code evaluates addr once, your new code evaluates it twice.
Have you tried an inline function instead of a macro?
linux/fs/binfmt_elf.c contains a few lines that probably break if 'addr' is evaluated twice:
<<<<<<<
argv = (elf_caddr_t *) sp;
if (!ibcs) {
__put_user((elf_addr_t)(unsigned long) envp,--sp);
__put_user((elf_addr_t)(unsigned long) argv,--sp);
}
<<<<<<<<<
