    kernel - Turn off zeroidle in the release branch.
    
    * Turn of automatic page zeroing when idle in the release branch.  This
      code has been completely removed in the master branch.  Pre-zeroing of
      pages no longer has any benefit on modern cpus for a multitude of reasons.
    
    * Will result in a small improvement in performance under heavy SMP loads.
