Date: Thu, 30 Apr 2009 20:01:29 -0400 Message-Id: <1241136098-10376-3-git-send-email-tabbott@mit.edu> X-Mailer: git-send-email 1.6.2.1 In-Reply-To: <1241136098-10376-2-git-send-email-tabbott@mit.edu> References: <1241136098-10376-1-git-send-email-tabbott@mit.edu> <1241136098-10376-2-git-send-email-tabbott@mit.edu> 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: 1647 Lines: 51 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.
