    kernel - Fix spin lock held across contigfree/kfree in bounce code
    
    * Fix an issue where a spin lock is being held across too-complex a
      procedure call.  The bounce page is isolated once removed from its
      list so we can release the lock while issuing the calls, then
      re-acquire it.
