Interrupt Latency

I was perusing the sources for 1.3.77 versus 1.3.72 in the hopes of noticing
why people are finding interrupt latency problems with post 1.3.72 kernels. I
noticed that in timer_bh the order between the code in run_old_timers and
run_timer_list is opposite between these two kernels, and there might also be
issues of where interrupts are enabled or not. Specifically, in 1.3.72
run_timer_list is executed before run_old_timers, but in 1.3.77 run_old_timers
comes first.
Was there a reason for this change?
