This is a resend of those patches with fixups after the latest changes

[PATCH 1/3] ARM: zImage: ensure it is always a multiple of 64 bits in size
This one is new and trivial.

This is needed for proper alignment when the DTB appending feature
is used.

This patch provides the ability to boot using a device tree that is appended
to the raw binary zImage (e.g. cat zImage filename.dtb zImage_w_dtb).

The appended DTB gets relocated with the decompressor code to get out
of the way of the decompressed kernel. However the .bss section may
be larger than the relocated code and data, therefore overwriting the
DTB. Let's make sure the relocation takes care of moving zImage so
no conflict with .bss
