Date: Wed, 16 Sep 2009 16:44:29 -0400 Message-Id: <1253133870-25140-5-git-send-email-tabbott@ksplice.com> X-Mailer: git-send-email 1.6.3.3 In-Reply-To: <1253133870-25140-1-git-send-email-tabbott@ksplice.com> References: <1253133870-25140-1-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 The .data.idt section is just squashed into the .data.page_aligned output section by the linker script anyway, so it might as well be in the .data.page_aligned section. This eliminates all references to .data.idt on x86.
