The option nohz_full for real time kernel does not work
Issue
When booting with kernel 3.10.0-229.rt56.161.el6rt.x86_64 all the CPUs have the same number of LOC in /proc/interrupts :
$ grep LOC /proc/interrupts
LOC: 2334621 2329252 2333683 2325669 2325495 2325633 2325443 2325914 2325622 2325622 2325623 2325589 2325579 2325626 2325435 2325844 Local timer interrupts
With the previous kernel version we seem to have the correct behaviour:
$ cat /proc/interrupts | grep LOC
LOC: 204884854 53953 5797157 27218 181629 26978 95005 26956 76224 26886 78968 26849 76086 26805 78739 26725 Local timer interrupts
