From d5ccde0a64c3dbe954a8a13a6ba9fb3b6d7c6225 Mon Sep 17 00:00:00 2001
From: Kyle McMartin <kyle@redhat.com>
Date: Thu, 14 Oct 2010 22:31:11 -0400
Subject: alpha: use set_irq_chip and push down __do_IRQ to the machine types

Also kill superfluous IRQ_DISABLED initialization, since that's the
default state of the irq_desc[i].status field.

From a891b393dd7f6ed84ecee98c0eac4a808ff2cbbc Mon Sep 17 00:00:00 2001
From: Kyle McMartin <kyle@redhat.com>
Date: Thu, 14 Oct 2010 22:31:25 -0400
Subject: alpha: irq clean up

Stop touching irq_desc[irq] directly, instead use accessor
functions provided. Use irq_has_action instead of directly
testing the irq_desc.

Subject: alpha: fix breakage caused by df9ee29270

Commit df9ee29270 made arch_local_irq_save and arch_local_irq_restore
static inline which with -Werror trips up on __set_hae() and _set_hae()
which are extern inline.  The naive solution is to make __set_hae() and
set_hae() static inline but for reasons described in commit d559d4a24a3fe
this breaks the generic kernel build.  Instead, since this is architecture
specific code, this patch hard wires in the architecture specific method
f disabling and enabling interrupts.

Subject: alpha: fix WARN_ON in __local_bh_enable()

Interrupts ought to be disabled _before_ irq_enter().
