Subject: [PATCH 2/2] s390: clean up linker script using new linker script macros.
Date: Fri, 31 Jul 2009 16:58:31 -0400 [thread overview]
Message-ID: <1249073911-30208-2-git-send-email-tabbott@ksplice.com> (raw)
In-Reply-To: <1249073911-30208-1-git-send-email-tabbott@ksplice.com>
From: Nelson Elhage <nelhage@ksplice.com>
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.
