[PATCH 10/25] fs: move ext2 ioctl32 handlers into file systems



The same ioctls (originally from ext2) are used on ext2, ext3,
hfsplus, cifs, reiserfs and xfs. Since they are really compatible
between 32 and 64 bit except for the ioctl number, the conversion
handler is trivial and I copy it to each of these file systems
in order to eventually get rid of fs/compat_ioctl.c completely.

Ext3 and reiserfs actually have some more ioctl numbers that have
the same problem as the others, so I'm adding the conversion for
those in the same place.

XFS already handled these ioctl numbers in its existing ioctl32
code, but appeared to get it wrong.
