Don't make it a question.
In general any ioctl in any driver runnable on any 64bit architecture that has a 32bit compat layer should have compat support. Not having it is a bug.
However the new standard way to do this is to not add new stuff into compat_ioctl.c, but define ->compat_ioctl entry points in the low level drivers (and ideally converted them to ->unlocked_ioctl too while you're at it)
