+Subject: [PATCH] lockdep: Fix compilation error for !CONFIG_MODULES and
+ !CONFIG_SMP
+
+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.
