If sizeof(dma_addr_t) == 8, you're clearly introducing a 4-byte hole

It's always good to inspect the .kos with pahole after modifying
structures to make sure there are no regressions.

Pretty off topic but I have a dumb question - how do you dump a struct
with pahole using debug info or BTF from a random .ko?
Ever since pahole got converted to BTF modules stopped working for me :S
I never cared enough to check as most interesting stuff is built-in
in Meta's kernels but it annoys me every now and then..
