Sorry Dave,
My mail client line wrapped the patch. I will resend the lot
Please ignore the previous set. 

The following patch provides 32 bit userland ioctl support for modular (x.25 
type) 
socket ioctls in a 64 bit kernel. Since the the register_ioctl32_conversion() 
is now obsolete, this patch provides a mechanism to allow 32 bit user space 
ioctls to reach the kernel.
