Subject: [PATCH 3/6] x86: signal: move sigframe.h to arch/x86/include/asm
Date: Wed, 17 Dec 2008 18:50:32 -0800	[thread overview]
Message-ID: <4949BA78.2060002@ct.jp.nec.com> (raw)
In-Reply-To: <4949B9B5.2050701@ct.jp.nec.com>

From: Hiroshi Shimamoto <h-shimamoto@ct.jp.nec.com>

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.
