Subject: [PATCHv4 03/10] arm64: Move some macros under #ifndef __ASSEMBLY__
Date: Tue, 29 Nov 2016 10:55:22 -0800	[thread overview]
Message-ID: <1480445729-27130-4-git-send-email-labbott@redhat.com> (raw)
In-Reply-To: <1480445729-27130-1-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.
