Subject: [RFT/RFC PATCH 5/6] ARM: move the .idmap.text section closer to .head.text
Date: Thu, 12 Mar 2015 18:38:11 +0100 [thread overview]
Message-ID: <1426181892-15440-6-git-send-email-ard.biesheuvel@linaro.org> (raw)
In-Reply-To: <1426181892-15440-1-git-send-email-ard.biesheuvel@linaro.org>
This moves the .idmap.text section closer to .head.text, so that
relative branches are less likely to go out of range if the kernel
text gets bigger.
