this is the version of !defined(HAVE_COMPAT_IOCTL) from debian
.....there is no "!defined(HAVE_COMPAT_IOCTL)" that you said..

void NV_API_CALL os_register_ioctl32_conversion(U032 cmd, U032 size)
{
#if defined(NVCPU_X86_64) && defined(CONFIG_IA32_EMULATION)
unsigned int request = _IOWR(NV_IOCTL_MAGIC, cmd, char[size]);
register_ioctl32_conversion(request, (void *)sys_ioctl);
#endif /* NVCPU_X86_64 */
}

void NV_API_CALL os_unregister_ioctl32_conversion(U032 cmd, U032 size)
{
#if defined(NVCPU_X86_64) && defined(CONFIG_IA32_EMULATION)
unsigned int request = _IOWR(NV_IOCTL_MAGIC, cmd, char[size]);
unregister_ioctl32_conversion(request);
#endif /* NVCPU_X86_64 */
}
