In the following code (ppc), shouldn't first be either declared static
or deleted? To me it looks like first is always equal to one when the
else clause is evaluated.
You're right. "first" doesn't need to be there at all, it's probably an
old copy of something in the kernel.
asmlinkage int __ipipe_grab_irq(struct pt_regs *regs)
{
extern int ppc_spurious_interrupts;
ipipe_declare_cpuid;
int irq, first = 1;
if ((irq = ppc_md.get_irq(regs)) >= 0) {
__ipipe_handle_irq(irq, regs);
first = 0;
} else if (irq != -2 && first)
ppc_spurious_interrupts++;
ipipe_load_cpuid();
return (ipipe_percpu_domain[cpuid] == ipipe_root_domain &&
!test_bit(IPIPE_STALL_FLAG,
&ipipe_root_domain->cpudata[cpuid].status));
}
