Couple nitpicks:

> #if HZ=1000

#if HZ==1000

> #define       MSEC_TO_JIFFIES(msec) (msec)
> #define JIFFIES_TO_MESC(jiffies) (jiffies)
> #elif HZ=100

#elif HZ==100

> #define       MSEC_TO_JIFFIES(msec) (msec * 10)
> #define JIFFIES_TO_MESC(jiffies) (jiffies / 10)

#define JIFFIES_TO_MSEC(jiffies) (jiffies / 10)

> #else
> #define       MSEC_TO_JIFFIES(msec) ((HZ * (msec) + 999) / 1000)
> #define       JIFFIES_TO_MSEC(jiffies) ...
> #endif
