OK, I see.

I doubt CONFIG_VMSPLIT_3G/CONFIG_PAGE_OFFSET isn't
used at all in your unmerged patchset, also your link script should
be different with in-tree arch/arm/kernel/vmlinux.lds.S, otherwise
you may put all your kernel symbols after 0xC00000000.

Maybe you need to not define PAGE_OFFSET and let it be
PHYS_OFFSET at default, also VMSPLIT_3G shouldn't have
been there on non-MMU linux.
