Subject: [PATCH 01/39] x86/asm-offsets: Move TSS_sp0 and TSS_sp1 to asm-offsets.c
Date:   Wed, 18 Jul 2018 11:40:38 +0200
Message-Id: <1531906876-13451-2-git-send-email-joro@8bytes.org>
In-Reply-To: <1531906876-13451-1-git-send-email-joro@8bytes.org>
References: <1531906876-13451-1-git-send-email-joro@8bytes.org>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

From: Joerg Roedel <jroedel@suse.de>

These offsets will be used in 32 bit assembly code as well,
so make them available for all of x86 code.
