Subject: [PATCH v3 16/29] x86: entry, annotate interrupt symbols properly
Date: Fri, 21 Apr 2017 16:12:52 +0200 [thread overview]
Message-ID: <20170421141305.25180-16-jslaby@suse.cz> (raw)
In-Reply-To: <20170421141305.25180-1-jslaby@suse.cz>
* annotate local functions properly by SYM_FUNC_START_LOCAL and
SYM_FUNC_END
* use SYM_FUNC_INNER_LABEL for functions being in the middle of others
* mark the end of common_interrupt by SYM_FUNC_END
