Eduard - Gabriel Munteanu ca31e146d5 Move _RET_IP_ and _THIS_IP_ to include/linux/kernel.h
These two macros are useful beyond lock debugging. Moved definitions from
include/linux/debug_locks.h to include/linux/kernel.h, so code that needs
them does not have to include the former, which would have been a less
intuitive choice of a header.
