Commit 11bbb235c26f ("rcu: Use DEFINE_PER_CPU_SHARED_ALIGNED for
rcu_data") replaced DEFINE_PER_CPU by DEFINE_PER_CPU_SHARED_ALIGNED in
the definition of rcu_sched and rcu_bh without updating
kernel/rcu/tree.h.This makes clang report a section mismatch (-Wsection warning) when building LLVMLinux because the variables are declared in .data..percpu but defined in .data..percpu..shared_aligned.
