The alignment guarantees are clearly documented and objects are misaligned
in debugging kernels.

Looking at 3acd48507dc43eeeb:Looks like no one tested that patch with a
debug kernel or full debugging on until it hit mainline. Not good.

The consequence for the lack of proper testing is to make the production
kernel contain the debug measures?
