I thought of a better way of doing this.  They're still fuckwits though.

#if BITS_PER_LONG == 32
#ifdef __BIG_ENDIAN
#define LOFF_T(high, low) unsigned int high, unsigned int low
#else
#define LOFF_T(high, low) unsigned int low, unsigned int high
#endif
asmlinkage long sys_truncate64(const char * path, LOFF_T(high, low))
{
	return do_sys_truncate(path, (loff_t)high << 32 | low);
}

asmlinkage long sys_ftruncate64(unsigned int fd, LOFF_T(high, low))
{
	return do_sys_ftruncate(fd, (loff_t)high << 32 | low);
}
#endif
