The build blows up on me with this commit added to my tty-testing tree:

In file included from ./arch/x86/include/generated/uapi/asm/termios.h:1,
                 from ./include/uapi/linux/termios.h:6,

                 from ./include/linux/vt_kern.h:12,
                 from drivers/gpu/drm/vboxvideo/vbox_drv.c:12:
./include/asm-generic/termios.h:70:5: error: conflicting types for ‘user_termio_to_kernel_termios’; have ‘int(struct ktermios *, struct termio *)’

      |     ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~
./include/asm-generic/termios.h:20:19: note: previous definition of ‘user_termio_to_kernel_termios’ with type ‘int(struct ktermios *, const struct termio *)’

Lots of stuff like that.

I'll take the first 2 in my tree, but stop here.
