rcu: Move RCU debug Kconfig options to kernel/rcu
RCU's debugging Kconfig options are in the unintuitive location lib/Kconfig.debug, and there are enough of them that it would be good for them to be more centralized. This commit therefore extracts RCU's Kconfig options from init/Kconfig into a new kernel/rcu/Kconfig.debug file. Reported-by: Ingo Molnar <mingo@kernel.org> Signed-off-by: Paul E. McKenney <paulmck@linux.vnet.ibm.com>
