- Diagnose 8 needs a response buffer below 2GB real storage.
  As the caller cannot always allocate the buffer with GFP_DMA the best
  solution is to rewrite cpcmd to use a bounce buffer if necessary.
  The old function was renamed to __cpcmd and can be called if appropriate.
  The early boot code does not provide kmalloc but need cpcmd functionality.
  These places have been converted to use __cpcmd, as the init code and data
  are below 2GB.
- In case of an 31 bit system, cpcmd is defined as __cpcmd.
- EXPORT_SYMBOL(cpcmd) moved into cpcmd.c
- some whitespace fixes in cpcmd.[c/h]
