Subject: [PATCH v6 1/2] x86/kasan: define KASAN_SHADOW_OFFSET per architecture
Date: Thu, 13 Aug 2015 08:37:23 +0300 [thread overview]
Message-ID: <1439444244-26057-2-git-send-email-ryabinin.a.a@gmail.com> (raw)
In-Reply-To: <1439444244-26057-1-git-send-email-ryabinin.a.a@gmail.com>
Current definition of KASAN_SHADOW_OFFSET in include/linux/kasan.h
will not work for upcomming arm64, so move it to the arch header.
