rcu: Remove SPARSE_RCU_POINTER Kconfig option
The sparse-based checking for non-RCU accesses to RCU-protected pointers has been around for a very long time, and it is now the only type of sparse-based checking that is optional. This commit therefore makes it unconditional. Reported-by: Ingo Molnar <mingo@kernel.org> Signed-off-by: Paul E. McKenney <paulmck@linux.vnet.ibm.com> Cc: Fengguang Wu <fengguang.wu@intel.com>

- This feature enables the __rcu sparse annotation for
- RCU-protected pointers. This annotation will cause sparse
- to flag any non-RCU used of annotated pointers. This can be
- helpful when debugging RCU usage. Please note that this feature
- is not intended to enforce code cleanliness; it is instead merely
- a debugging aid.
-
- Say Y to make sparse flag questionable use of RCU-protected pointers
-
- Say N if you are unsure.
