- Don't return uninitialised stack values in case of allocation failure

- Don't bother clearing PageCompound because __GFP_COMP wasn't specified
  Increment over the pte page rather than one pte entry in
  pte_alloc_one_kernel

- Actually increment the page pointer in pte_alloc_one

- Compile fixes, typos.
