Define a capture function for each irq
catch_irq_10( ...){ common_irq(10); ...}
Or, in V3 RTLinux us the sigaction call to install a handler and the
first argument is the irq#, or, in earlier versions of RTLinux
use rtl_request_irq and the first argument is the irq#, or you can
can extract the signal number from the pt_regs argument -- in x86 it is in
the eax field.
