Hi Ingo,

  CC      kernel/latency_hist.o
  kernel/latency_hist.c: In function 'u64_div':
  kernel/latency_hist.c:54: error: implicit declaration of function 'do_div'
  make[1]: *** [kernel/latency_hist.o] Error 1
  make: *** [kernel] Error 2

This was needed to compile rt0 with LATENCY_TRACE on i386:

Add asm/div64.h header to define do_div()
