Hi Arnd,
The current asm-generic/uaccess unit copy interface __{get,put}_user( )
defaults to using __copy_{to,from}_user( ). For archs which don't support
unaligned access, latter typically involves generated code for alignment
checks.
It is expected that arch will provide a

Driver for non-standard on-chip UART, instantiated in the ARC (Synopsys)
FPGA Boards such as ARCAngel4/ML50x
v2:
* ttyARC used as device name
* Dynamic assignment of major/minor numbers.
* Ref counting tty in rx routine to prevent it from disappearing in
case of a hangup
