A cloned data section has to keep its sh_addralign. Plenty of kernel data
is aligned for correctness rather than speed -- per-CPU variables, anything
touched by an aligned vector move, structures padded to own a cacheline --
and a clone that lands under-aligned either faults on first use or silently
shares a line it was laid out to avoid. Neither shows up until the patch
is loaded on hardware that cares.
The fixture's data is new in the patched build, so klp diff has to clone it
rather than reference the kernel's copy, and it asserts that premise before
asserting the result.
