[RFC PATCH 0/2] Remove at91 workaround from handle_IRQ

[Will Deacon]

Hello,

This is a couple of patches that I wrote quickly to try and remove the
irq_finish hook from handle_IRQ on ARM. Currently, the hook is only used
by at91 in order to issue an EOI when using level_irq flow control.

This patch moves the at91 irq_chip to fasteoi flow control, removing the
need for the additional hook. Since I (a) don't know anything about at91
(the TRM I found for the IRQ controller is only a few pages long) and (b)
don't have a platform on which to test, this is very much an RFC series.

All comments welcome.

Will
