Date: Fri, 18 Sep 2009 16:32:47 -0400 Message-Id: <1253305969-6948-5-git-send-email-tabbott@ksplice.com> X-Mailer: git-send-email 1.6.3.3 In-Reply-To: <1253305969-6948-1-git-send-email-tabbott@ksplice.com> References: <1253305969-6948-1-git-send-email-tabbott@ksplice.com> X-Spam-Flag: NO X-Spam-Score: 0.00 Sender: linux-kernel-owner@vger.kernel.org List-ID: X-Mailing-List: linux-kernel@vger.kernel.org Content-Length: 1559 Lines: 42 It appears that m32r copied the .altinstructions definition from x86 when the architecture was first merged into Linux. m32r doesn't put anything in .altinstructions, so this is just dead code. The following block affecting .exit.text/.exit.data, which has a comment also copied from x86, should also be deleted; the linker script later discards the .exit.text and .exit.data sections.
