Subject: [PATCH v2] sched: Fix some spelling mistakes in the scheduler module

From: "jianyun.gao" <jianyungao89@...il.com>

The following are some spelling mistakes existing in the scheduler
module. Just fix it!

  slection -> selection
  achitectures -> architectures
  excempt -> except
  incorectly -> incorrectly
  litle -> little
  faireness -> fairness
  condtion -> condition
