Subject: [PATCH v2 05/10] x86: kernel+lib, annotate local functions
Date: Mon, 20 Mar 2017 13:32:17 +0100	[thread overview]
Message-ID: <20170320123222.15453-5-jslaby@suse.cz> (raw)
In-Reply-To: <20170320123222.15453-1-jslaby@suse.cz>

Use the newly added SYM_FUNC_START_LOCAL to annotate starts of all
functions which do not have ".globl" annotation. This is needed to
balance SYM_FUNC_END for tools that are about to generate debuginfo.

In this patch, do it for local verify_cpu, early_idt_handler_common, and
bad_*_user properly.  Note that early_idt_handler_common already had
ENDPROC -- switch to the new SYM_FUNC_END.
