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 consider it
a "TODO".

#define TICK_USEC ((1000000UL + USER_HZ/2) / USER_HZ)
