NetBSD/sys/dev/hpc/hpcfb.c
jmmv 7a51d4dddc Add an extra cookie to the ioctl and mmap wsdisplay accessops that points 
to the screen on which they are being called.  The driver cannot guess
this by itself but it is needed to implement, at least, the getwschar and
putwschar functions in the correct place.  There are no functional changes
yet.

Tested on i386 (vga, vga_raster, machfb, vesafb), macppc and sparc64.
Suggested and reviewed by macallan@.
