This simplifies compat32 ioctl handling and removes compat_alloc_user_space()
and copy_in_user() from the kernel.
Tested this with the contrib/test/test-media script and both the 64 and 32 bit
versions of v4l2-ctl and v4l2-compliance ('sudo test-media mc' and
'sudo test-media -32 mc').
Arnd, thank you for your work on this!
Regards,
Hans
