+Subject: [PATCH] Serial ioctl() workaround
+
+The ioctls.h of some architectures (notably xtensa) references structs from
+linux/serial.h. Make sure to include this header as well.
+
+Also, undef TIOCTTYGSTRUCT that require reference to internal kernel tty_struct,
+but isn't actually referenced in modern kernels.
