Subject: [PATCH 3/3] FRV: Mark __do_IRQ() deprecated

From: David Howells <dhowells@...hat.com>

Mark __do_IRQ() as being deprecated (as Ben Herrenschmidt says it is).

Rename the real __do_IRQ() to __do_IRQ_deprecated() and wrap this in an inline
function called __do_IRQ() that is deprecated to prevent generic_handle_irq()
from giving deprecation warnings on every file.
