Subject: [PATCH v6 28/28] x86/asm: replace WEAK uses by SYM_INNER_LABEL
Date:   Fri, 18 May 2018 11:17:21 +0200
Message-Id: <20180518091721.7604-29-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

Use the new SYM_INNER_LABEL for WEAK entries in the middle of x86
assembly functions.

And make sure WEAK is not defined for x86 anymore as these were the last
users.
