Yes, I think my new patch fixed that problem. However, if= you're trying to hide
jiffies.h it will eventually failed at = some other place due to the "unsigned long"
integer postfix (i.e. the "UL" in 100000UL), which hideif still c= onsider it a "TODO".

#define TICK_USEC ((1000000UL + USER_= HZ/2) / USER_HZ)
