Subject: [PATCH v6 03/28] x86/asm/suspend: use SYM_DATA for data
Date:   Fri, 18 May 2018 11:16:56 +0200
Message-Id: <20180518091721.7604-4-jslaby@suse.cz>
In-Reply-To: <20180518091721.7604-1-jslaby@suse.cz>
References: <20180518091721.7604-1-jslaby@suse.cz>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Some global data in the suspend code were marked as `ENTRY'. ENTRY was
intended for functions and shall be paired with ENDPROC. ENTRY also
aligns symbols which creates unnecessary holes here between data. Since
we are dropping historical markings, make proper use of newly added
SYM_DATA in this code.
