Hi Andrew.
The attached patch moves the IRQ-related SA_xxx flags (namely, SA_PROBE, SA_SAMPLE_RANDOM and SA_SHIRQ) from all the arch-specific headers to linux/signal.h. This looks like a left-over after the irq-handling code was consolidated. The code was moved to kernel/irq/*, but the flags are still left per-arch.
Right now, adding a new IRQ flag to the arch-specific header, like this patch does: http://cvs.sourceforge.net/viewcvs.py/*checkout*/alsa/alsa-driver/utils/patches/pcsp-kernel-2.6.10-03.diff?rev=1.1 no longer works, it breaks the compilation for all other arches, unless you add that flag to all the other arch-specific headers too. So I think such a clean-up makes sense.
Can this please be applied? Unfortunately I have tested it on x86 only.
