 * SA_STATIC_ALLOC is used for the sparc32 system to indicate that this
 * interrupt handler's irq structure should be statically allocated
 * by the request_irq routine.
 * The alternative is that arch/sparc/kernel/irq.c has carnal knowledge
 * of interrupt usage and that sucks. Also without a flag like this
 * it may be possible for the free_irq routine to attempt to free
 * statically allocated data.. which is NOT GOOD.
