Hi all,
After merging the tip tree, today's linux-next build (arm
multi_v7_defconfig) failed like this:
kernel/tracepoint.c: In function 'tracepoint_remove_func':
kernel/tracepoint.c:253:4: error: implicit declaration of function 'static_key_slow_dec_cpuslocked' [-Werror=implicit-function-declaration]
static_key_slow_dec_cpuslocked(&tp->key);
^
Caused by commit
24db7a671bd5 ("trace/perf: Cure hotplug lock ordering issues")
static_key_slow_dec_cpuslocked() is only defined if HAVE_JUMP_LABEL is
set - which is only defined if defined(CC_HAVE_ASM_GOTO) &&
defined(CONFIG_JUMP_LABEL). CONFIG_JUMP_LABEL is not set for this build.
I wasn't sure if just adding
#define static_key_slow_dec_cpuslocked static_key_slow_dec
in the !HAVE_JUMP_LABEL case in include/linux/jump_label.h would be
sufficient, so I have reverted that commit for today.
