Commit f629307c857c030d5a3dd777fee37c8bb395e171 introduced uses of
kernel_termios_to_user_termios_1 and user_termios_to_kernel_termios_1
on all architectures. However, powerpc, s390, avr32 and frv don't
currently define those functions since their termios struct didn't
need to be changed when the arbitrary baud rate stuff was added, and
thus the kernel won't currently build on those architectures.
alpha, parisc, sh, sparc{64,}, xtensa are still broken with this error...
They need to include <asm-generic/termios.h> in asm-<arch>/termios.h
like in powerpc.
Alternatively tonyb's patch should fix them. Could also do that?
