Add extra parentheses around a couple of definitions introduced by
"x86: Cleanup vector usage" and used in assembly macro arguments, and
remove spaces. Without that old (2.16.1) gas would see more macro
arguments than were actually specified.

Wondering, have you managed to test this with 2.16, or should i wait for akpm's
testing before applying it?
Thanks,
Ingo

Add extra parentheses around a couple of definitions introduced
by "x86: Cleanup vector usage" and used in assembly macro
arguments, and remove spaces. Without that old (2.16.1) gas
would see more macro arguments than were actually specified.

Yes, and we can push this to Linus only once that's been resolved. I trust you to
queue up the real solution or come up with good reasons why that is not possible for
GAS 2.16. (at which point we'll just have to live with the ugliness, up to the point
we decide to deprecate binutils 2.16.)
Meanwhile, what i hate more than ugly code repetition is code that does not build at
all on akpm's test environment ;-)
Thanks,
Ingo

I hadn't got around to testing it. Bad news :(

There much be some magic workaround for this within apicinterrupt but I
didn't find it.

Andrew,
can you this on your side? this is what Jan proposed. I can only test a
latest binutils here.
Thanks,

Indeed - the problem isn't with the actual assembly construct, but
rather with the changed definitions of *INVALIDATE_TLB_VECTOR* -
properly parenthesizing them (as we needed to do in other places)
and removing unnecessary spaces gets this to build for me, even
with the original use of .irp instead of .irpc:
#if NR_CPUS <= 32
# define NUM_INVALIDATE_TLB_VECTORS (NR_CPUS)
#else
# define NUM_INVALIDATE_TLB_VECTORS (32)
#endif
#define INVALIDATE_TLB_VECTOR_END (0xee)
#define INVALIDATE_TLB_VECTOR_START \
(INVALIDATE_TLB_VECTOR_END-NUM_INVALIDATE_TLB_VECTORS+1)

That looks much nicer!
Mind sending a patch? I zapped the original non-working workaround from -tip.
Thanks,

btw, binaries for the offending binutils are at

I tried, but fails at early stage (not related to the problem). According
to HPA, I need rebuild gcc too, which I haven't done yet.
