Subject: [PATCH 003/365] 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.
