Hi,
This patch makes 2.1.31 compile on uniprocessor machines. Otherwise the macro in_interrupt() (used e.g. by the scsi layer) generates undefined symbol symbol errors. I'm not 100% sure if this is the right fix or if it would be better to define in_interrupt in asm-i386/hardirq.h to (intr_count). At least it works for me and didn't crash my machine yet ;)
Is local_irq_count[] supposed to be used on uni processor machines too? What is the difference between intr_count and local_irq_count[]? It would be nice if someone knowledgeable could comment on this.
Thanks, -Andi
