Content-Disposition: inline; filename=125-vmlinux-lds-2.diff Sender: linux-kernel-owner@vger.kernel.org List-ID: X-Mailing-List: linux-kernel@vger.kernel.org From: Nelson Elhage Note that this patch moves .data.init_task inside _edata. In addition, the alignment of .init.ramfs changes: It is now PAGE_ALIGNED and __initramfs_end is arbitrarily aligned; Previously it was only aligned to a 0x100-byte boundary, and always ended on an even byte. This change results in fewer output sections and in some data being reordered, but should have no functional effect.
