[PATCH] move SA_xxx defines to linux/signal.h

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.
