read/write functions and various other types of functions. Introduced new structures and macros to make this possible. To take advantage of this, a device must change its interface to replace and read/write callbacks with the new devcb_read/write structures. During device start time, the device then uses this new devcb module to resolve the information in the devcb_read/write structures into a more efficient form. When the device needs to call one of the callbacks, it uses the inline devcb_call_read/write functions. Once a device has defined its callbacks as devcb_read/write structures, users of the device must use the DEVCB_* macros to specify the type and information about the handler to use: DEVCB_NULL = no handler DEVCB_HANDLER = a standard device read/write handler DEVCB_MEMORY_HANDLER = a memory address space read/write handler DEVCB_DEVICE_HANDLER = a device read/write handler for a different device DEVCB_INPUT_PORT = an input port Converted the 8255PPI device to use this new structure, and updated all users to use the DEVCB macros, removing some unnecessary trampoline functions along the way.
