Subject: [PATCH 17/18] Disabled bus scan time PCI IRQ assignment on parisc
Date: Thu,  2 Oct 2014 05:07:45 +0100	[thread overview]
Message-ID: <1412222866-21068-18-git-send-email-matt@masarand.com> (raw)
In-Reply-To: <1412222866-21068-1-git-send-email-matt@masarand.com>

From: Matthew Minter <matt@masarand.com>

Most of the architectures are switched to allocating IRQs at device_enable
time instead of boot time, however parisc does not provide an easy way of
making that transition so the new code is disabled here on parisc.
