[PATCH] Fix irq handling of IO-APIC edge IRQs on UP
send_IPI_self is needed to resend irqs with IRQ_PENDING status when
enabled.
Checked with Ingo, and it's in 2.4-ac for some time.
This should fix ide lost interrupts on UP with IO-APIC
Ide trigers it this way:
- disable_irq
- do stuff that triggers IRQ.
- irq is IRQ_PENDING
- enable_irq
- IRQ is lost, needs to be resend.
I'll send the patch to fixup IDE disable_irq logic to Bart.
