Subject: [PATCH 3/7] ARM: vmlinux.lds: move discarded sections to beginning
Date: Wed, 06 Jul 2011 11:23:50 +0100 [thread overview]
Message-ID: <E1QePGo-0004zh-D2@rmk-PC.arm.linux.org.uk> (raw)
In-Reply-To: <20110706102245.GO8286@n2100.arm.linux.org.uk>
Rather than scattering the discarded sections throughout the linker
file, move them to the start.
Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
