From: Andi Kleen <andi@firstfloor.org> To: x86@kernel.org Cc: linux-kernel@vger.kernel.org, Andi Kleen <ak@linux.intel.com> Subject: [PATCH 04/16] x86, asmlinkage: Make _*_start_kernel visible Date: Mon, 5 Aug 2013 15:02:38 -0700 Message-ID: <1375740170-7446-5-git-send-email-andi@firstfloor.org> (raw) In-Reply-To: <1375740170-7446-1-git-send-email-andi@firstfloor.org> From: Andi Kleen <ak@linux.intel.com> Obviously these functions have to be visible, otherwise the whole kernel could be optimized away.
