Software IRQ processing in generic architectures assumes that the
exit out of hard IRQ may have re-enabled interrupts (some
architectures may have an implicit EOI). It presumes them enabled
and toggles the flags once more just in case unless this is turned
off in the architecture specific hardirq.h by setting
__ARCH_IRQ_EXIT_IRQS_DISABLED
This patch adds this to UML where due to the way IRQs are handled
it is an optimization (it works fine without it too).
