[PATCH] Ioctl compatibility for TIOCMIWAIT and TIOCGICOUNT

[Paul Mackerras]

This patch lets us use TIOCMIWAIT and TIOCGICOUNT from a 32-bit
process on a 64-bit processor.  TIOCMIWAIT uses the argument as a
bitmap of things to wait for.  The argument for TIOCGICOUNT points to
a struct serial_icounter_struct, which only contains ints and arrays
of int.
