From 4b34f7d62e558736ea4f1d15e9444522fc2ac6a8 Mon Sep 17 00:00:00 2001 From: Russell King Date: Wed, 6 Jul 2011 12:55:41 +0100 Subject: ARM: io: remove IO_SPACE_LIMIT from platforms without PCI/ISA Nothing should be using PCI/ISA IO on these platforms, so their IO_SPACE_LIMIT definitions are irrelevent.

This allows the nr_cpus command line option to work as expected.
