consolidate interrupt-related constants
PATCH 1/1 consolidate interrupt-related constants
Hello.
Attached patch moves the three interrupt-related constants, namely SA_PROBE, SA_SAMPLE_RANDOM and SA_SHIRQ, from the arch-specific headers to the generic header linux/signal.h. Now, as the interrupt handling code was recently consolidated, it looks likely that the related flags have to be either.
This is mainly only a cleanup, but it also makes a common place for adding the new arch-independant flags for interrupt handling.
For my drivers I just used to add such a flags into an i386-specific header since the drivers were intended to work only on that hardware. But now, as the interrupt handling code in kernel was consolidated, adding such a flags to the arch-specific header breaks the compilation for other archs, so I thought having a common place for that arch-independant flags would be good.
The problem with that patch is that I can't test it on something other than x86. But it may work as expected.
