Subject: [PATCH 4/7] ARM: vmlinux.lds: rearrange .init output section
Date: Wed, 06 Jul 2011 11:24:10 +0100	[thread overview]
Message-ID: <E1QePH8-0004zl-Gf@rmk-PC.arm.linux.org.uk> (raw)
In-Reply-To: <20110706102245.GO8286@n2100.arm.linux.org.uk>

Keep the various linker tables as separate output sections rather
than combining them together into one big .init section.  This
makes the 'vmlinux' easier to see what is placed where.
