Peter Anvin" Cc: linux-kernel@vger.kernel.org Subject: [PATCH 3/6] x86: signal: move sigframe.h to arch/x86/include/asm References: <4949B9B5.2050701@ct.jp.nec.com> In-Reply-To: <4949B9B5.2050701@ct.jp.nec.com> Content-Type: text/plain; charset=ISO-8859-1 Content-Transfer-Encoding: 7bit Sender: linux-kernel-owner@vger.kernel.org List-ID: X-Mailing-List: linux-kernel@vger.kernel.org From: Hiroshi Shimamoto Impact: move header file Move arch/x86/kernel/sigframe.h to arch/x86/include/asm/sigframe.h. It will be used in arch/x86/ia32/ia32_signal.c.
