v2.4.2.4 -> v2.4.2.5

  - Rik van Riel and others: mm rw-semaphore (ps/top ok when swapping)
  - IDE: 256 sectors at a time is legal, but apparently confuses some
  drives. Max out at 255 sectors instead.
  - Petko Manolov: USB pegasus driver update
  - make the boottime memory map printout at least almost readable.
  - USB driver updates
  - pte_alloc()/pmd_alloc() need page_table_lock.
