sched: Always inline context_switch() When CONFIG_GCOV is enabled, gcc decides to put context_switch() out-of-line, which is inconsistent with its normal behavior. It also causes an objtool warning because __schedule() no longer inlines context_switch(), so the "STACK_FRAME_NON_STANDARD(__schedule)" statement loses its effect.
