kbuild: genksyms parser: fix the __attribute__ rule
We are having two kinds of problems with genksyms today: fake checksum changes without actual ABI changes, and changes which we would rather like to ignore (such as an additional field at the end of a structure that modules are not supposed to touch, for example). I have thought about ways to improve genksyms and compute checksums differently to avoid those problems, but in the end I don't see a fundamentally better way. So here are some genksyms patches for at least making the checksums more easily manageable, if we cannot fully fix them. In addition to the bugfixes (the first two patches), this allows genksyms to track checksum changes and report why a checksum changed (third patch), and to selectively ignore changes (fourth patch). This patch: Gcc __attribute__ definitions may occur repeatedly, e.g., static int foo __attribute__((__used__)) __attribute__((aligned (16))); The genksyms parser does not understand this, and generates a syntax error. Fix this case.
