Why does x86_64 support a SuSE-specific ioctl?

Hi,

arch/x86_64/ia32/ia32_ioctl.c in both 2.4.20-pre8 and 2.5.40 contains:

<-- snip -->

...
/* SuSE extension */
#ifndef TIOCGDEV
#define TIOCGDEV _IOR('T',0x32, unsigned int)
#endif
static int tiocgdev(unsigned fd, unsigned cmd, unsigned int *ptr)
{
...
}
...
HANDLE_IOCTL(TIOCGDEV, tiocgdev)
...

<-- snip -->

TIOCGDEV is (as the comment above indicates) in neither 2.4.20-pre9 nor in
2.5.40 and I'm wondering why the x86_64 kernel supports a SuSE-specific
i386 ioctl?

You only think this is a free country. Like the US the UK spends a lot of
time explaining its a free country because its a police state.
