I don't see anything obviously wrong here, and my main reaction is
actually that I wish this went a bit further, and moved the whole
kernel_termios_to_user_termios stuff into C code rather than having
them in headers.

I don't think it's really worth inlining those things, and I wonder if
we could just have the default "just copy directly to/from user space"
as __weak functions, and then allow sparc and alpha to override them?
