Subject: [PATCH v6 15/16] x86/init: disable pnpbios for X86_SUBARCH_INTEL_MID
Date: Wed, 13 Apr 2016 17:04:45 -0700 [thread overview]
Message-ID: <1460592286-300-16-git-send-email-mcgrof@kernel.org> (raw)
In-Reply-To: <1460592286-300-1-git-send-email-mcgrof@kernel.org>
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
