Re: Correct backtraces for do_IRQ

Amit,

I can't see that missing. common_interrupt is not a standalone routine;
the patch adds RING0_INT_FRAME to irq_entries_start, and all the
necessary annotations to SAVE_ALL. Thus I can't see how your patch would
even work together with mine. If things aren't working for you with the
patch I provided, we'd rather have to figure out what's broken with
that...

Yes, mainline gas meanwhile accepts them.
