[RFC PATCH 0/5] irq: Kill irq_reserve_irq

[Yinghai Lu]

Hi,

During reviewing ioapic hotplug patchset, Thomas pointed out that
should not extend irq_reserve_irq for that purpose as that is not
actually reserve.

Neet to clean up old irq_reserve_irq before introduce reserve/alloc_reserved
method for ioapic hotplug.

So here patchset that kill irq_reserve_irq that actually set allocated_irqs.

First remove irq_reserve_irqs for x86, and remove irq_reserve_irq
for sh.
Then in set_irq_chip use irq_alloc_desc instead of irq_reserve_irq.
At last will mark bits in allocated_irqs early for init irqs in !SPARSE_IRQ

Thanks

Yinghai
