Thanks for the feedback. We have taken care of these. There are two
follow-ups to do.
  1. moving whole or part of drivers/ata/ahci.h to include/linux
  2. mtip32xx support 32-bit ioctls too. For now, we have defined compat
equivalent of struct ide_task_request_s locally. We need this support in
hdreg.h
