percpu: use DEFINE_PER_CPU_SHARED_ALIGNED()
There are a few places where ___cacheline_aligned* is used with DEFINE_PER_CPU(). Use DEFINE_PER_CPU_SHARED_ALIGNED() instead. DEFINE_PER_CPU_SHARED_ALIGNED() applies alignment only on SMPs. While all other converted places used _in_smp variant or only get compiled for SMP, net/rds used unconditional ____cacheline_aligned. I don't see any reason these data structures should be aligned on UP and thus converted together.
