[PATCH] dm: 64 bit ioctl fixes

From: Joe Thornber <thornber@sistina.com>

Update the ioctl32 handlers for the 64-bit architectures to recognize
the new Device-Mapper version 4 ioctls. The version 1 ioctls are still
there.  If/When the version 1 ioctls are removed, these same files
will need to be updated again.

I have been unable to test this patch yet, since I have not had any
luck getting 2.6.0-test2 to compile on my ppc64 box (not a dm-related
problem).  But the patch is pretty trivial, so I'm pretty confident it
will work. If anyone else can test this (on mips64, sparc64, parisc,
or x86-64), let me know if you have any problems.  [Kevin Corry]
