Subject: [PATCH 5/5] tracing: Fix SKIP_STACK_VALIDATION=1 build due to bad merge with -mrecord-mcount
Date: Fri, 22 Jun 2018 21:20:40 -0400 [thread overview]
Message-ID: <20180623012105.578170331@goodmis.org> (raw)
[-- Attachment #1: 0005-tracing-Fix-SKIP_STACK_VALIDATION-1-build-due-to-bad.patch --]
[-- Type: text/plain, Size: 1344 bytes --]
From: Greg Thelen <gthelen@google.com>
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")
