The patch looks OK. But just for sanity's sake, is it guaranteed

the per_cpu data section will be greater than 4k on both architectures?
Or could there be some combination of xen CONFIG options that could
reduce the i386 per_cpu data section contents to less than 4K even though
PERCPU_SHIFT is 13?
PERCPU_SHIFT has only ever been 12 or 13 so far, and it's unlikely to ever
get smaller. Ongoing, we could help you out by defining some useful label in
our linker script. For example, __per_cpu_shift = PERCPU_SHIFT (or
'__per_cpu_start + PERCPU_SHIFT', as I'm not sure about creating labels
outside the virtual address ranges defined by the object file).
