Andy pointed out that binutils generates additional sections in the vdso
image (e.g. section string table) which, if our .text section gets big
enough, could cross a page boundary and end up screwing up the location
where the kernel expects to put the data page.
This patch solves the issue in the same manner as x86_32, by moving the
data page before the code pages.
