Where is the u64? My (x86_64) copy of /usr/include/linux/hpet.h looks like:

1 #ifndef __HPET__
2 #define __HPET__ 1
3
4
5
6
7 struct hpet_info {
8 unsigned long hi_ireqfreq; /* Hz */
9 unsigned long hi_flags; /* information */
10 unsigned short hi_hpet;
11 unsigned short hi_timer;
12 };
13
14 #define HPET_INFO_PERIODIC 0x0010 /* periodic-capable comparator */
15
16 #define HPET_IE_ON _IO('h', 0x01) /* interrupt on */
17 #define HPET_IE_OFF _IO('h', 0x02) /* interrupt off */
18 #define HPET_INFO _IOR('h', 0x03, struct hpet_info)
19 #define HPET_EPI _IO('h', 0x04) /* enable periodic */
20 #define HPET_DPI _IO('h', 0x05) /* disable periodic */
21 #define HPET_IRQFREQ _IOW('h', 0x6, unsigned long) /* IRQFREQ usec */
22
23 #endif /* !__HPET__ */
I guess s390 hpet.h looks different? Does it just need to #include <linux/types.h> ?
Or is the problem the kernel-space u64 vs. userspace __u64?

Any suggestions?
