due to improper use of int which shows up on 16 bit targets. Added
ioctl_command_t since IOCTL command argument does not reliably fit
into 16 bits.

warnings. Most of the warnings were 16/32 bit integer sizing issues.
Some constants had L appended, some had casts add, some types were
changed to reflect a bit width requirement.
