Subject: [Upstream] Stop ARM boards crashing with CUPS is loaded
Date: Mon, 12 Jul 2010 13:14:21 +0100	[thread overview]
Message-ID: <4C3B071D.10505@gmail.com> (raw)

[-- Attachment #1: Type: text/plain, Size: 402 bytes --]

Please find attached a patch which rectifies the following bug.

When CUPS loads, it tries to load several drivers that it may need.
When one of these drivers, specifically parport_pc is loaded on ARM
based systems, it causes a segmentation fault as the address is not
writable on non-PC based architectures. This code prevents this
driver from being compiled on said architectures.

Kind regards,
Lee
