Bug description:
  Reloading the Hyper-V LIS modules can sometime result in a kernel panic. 
  Technical details: a hypercall can return “invalid alignment”  error if the input parameter spans a page boundary. Updated LIS code handles properly the error without returning bug().

  We've triaged this issue internally and the following 2 patches have been created.
  Please include them in 14.10 (Utopic Unicorn)  daily builds and let us know when we can test.
