A few times, this error (it's not a warning) meant the
driver was attempting to access user space data directly.
This is wrong and unfortunately it *usually* (but not always)
works on x86 arch. The right way to access user space data
is via copy_from_user() or write asm code that explicitly
references Space Registers (eg sr3).
