So the problem is in scripts/mod/file2alias.c, which gives a different
sizeof(struct sdio_device_id) on the cross-compile host:
- sizeof(struct sdio_device_id) = 12 on ia32
- sizeof(struct sdio_device_id) = 10 on m68k
While file2alias.c has code to handle 32 vs. 64 bit correctly when
cross-compiling, it doesn't handle alignment differences between host
and target.

when I'm talking to journalists I just say "programmer" or something like that.
