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

You should say Y here if you have a PC-style parallel port. All
IBM PC compatible computers and some Alphas have PC-style
