4.4.50-rt63-rc1 stable review patch.
If anyone has any objections, please let me know.
------------------
From: Dan Murphy <dmurphy@xxxxxx>
When CONFIG_MODULES is not set then it fails to compile in lockdep:
|kernel/locking/lockdep.c: In function 'look_up_lock_class':
|kernel/locking/lockdep.c:684:12: error: implicit declaration of function
| '__is_module_percpu_address' [-Werror=implicit-function-declaration]
If CONFIG_MODULES is set but CONFIG_SMP is not, then it compiles but
fails link at the end:
|kernel/locking/lockdep.c:684: undefined reference to `__is_module_percpu_address'
|kernel/built-in.o:(.debug_addr+0x1e674): undefined reference to `__is_module_percpu_address'
This patch adds the function for both cases.
