Subject: [PATCHv7 08/11] arm64: Move some macros under #ifndef __ASSEMBLY__
Date: Tue, 10 Jan 2017 13:35:47 -0800	[thread overview]
Message-ID: <1484084150-1523-9-git-send-email-labbott@redhat.com> (raw)
In-Reply-To: <1484084150-1523-1-git-send-email-labbott@redhat.com>


Several macros for various x_to_y exist outside the bounds of an
__ASSEMBLY__ guard. Move them in preparation for support for
CONFIG_DEBUG_VIRTUAL.
