prepare_sleep_state():

Browse Source 
* Use the respective error types for OS and ACPICA functions.
* Don't lock the memory. The caller must do that, since there's no balancing
  function that would unlock the memory again.
* Get the memory map of the given function, not of the on-stack variable.
* Added 64 bit support and a check for the PAE case.
