Subject: [PATCH 3/4] arm64/efi-stub, kasan: don't instrument efi-stub.
Date: Wed, 26 Aug 2015 19:15:06 +0300 [thread overview]
Message-ID: <1440605707-8325-4-git-send-email-ryabinin.a.a@gmail.com> (raw)
In-Reply-To: <1440605707-8325-1-git-send-email-ryabinin.a.a@gmail.com>
efi-stub.c code runs before we setup early shadow.
Intrumentation of it will cause boot crash.
