[PATCH] common 32-bit ioctl code

From: Pavel Machek <pavel@suse.cz>

Various 64-bit architectures are duplicating a ton of 32-bit compat code.

Pavel's patch creates a generic 32-bit ioctl file in fs/compat_ioctl.c which
architectures will #include from within their arch/ layer.

Has been reviewed by everyone and tested on sparc64, x86_64, ppc64 and ia32.
