profile: hide unused functions when !CONFIG_PROC_FS ...
A couple of functions and variables in the profile implementation are
used only on SMP systems by the procfs code, but are unused if either
procfs is disabled or in uniprocessor kernels. gcc prints a harmless
warning about the unused symbols:
kernel/profile.c:243:13: error: 'profile_flip_buffers' defined but not used [-Werror=unused-function]
static void profile_flip_buffers(void)
^
kernel/profile.c:266:13: error: 'profile_discard_flip_buffers' defined but not used [-Werror=unused-function]
static void profile_discard_flip_buffers(void)
^
kernel/profile.c:330:12: error: 'profile_cpu_callback' defined but not used [-Werror=unused-function]
static int profile_cpu_callback(struct notifier_block *info,
^
This adds further #ifdef to the file, to annotate exactly in which cases
they are used. I have done several thousand ARM randconfig kernels with
this patch applied and no longer get any warnings in this file.
