Subject: [PATCH 4.4 23/35] tracing: Fix SKIP_STACK_VALIDATION=1 build due to bad merge with -mrecord-mcount
Date: Mon, 22 Feb 2021 13:36:19 +0100 [thread overview]
Message-ID: <20210222121021.390104014@linuxfoundation.org> (raw)
In-Reply-To: <20210222121013.581198717@linuxfoundation.org>
From: Greg Thelen <gthelen@google.com>
commit ed7d40bc67b8353c677b38c6cdddcdc310c0f452 upstream.
Non gcc-5 builds with CONFIG_STACK_VALIDATION=y and
SKIP_STACK_VALIDATION=1 fail.
Example output:
/bin/sh: init/.tmp_main.o: Permission denied
commit 96f60dfa5819 ("trace: Use -mcount-record for dynamic ftrace"),
added a mismatched endif. This causes cmd_objtool to get mistakenly
set.
Relocate endif to balance the newly added -record-mcount check.

Fixes: 96f60dfa5819 ("trace: Use -mcount-record for dynamic ftrace")
