As per hpa Intel MID platforms can also disable pnpbios [0]. As per 0-day, this bumps the vmlinux size using i386-tinyconfig as follows: TOTAL TEXT init.text x86_early_init_platform_quirks() -8 -8 -8 -8 [0] http://lkml.kernel.org/r/5702B5C2.7070101@zytor.com v6: add 0-day size impact Suggested-by: H.
