My tree also has this:

commit 5536f5491a2e098 

    softirq: keep the 'softirq pending' check RT-only
    
    The patch "nohz: Prevent erroneous tick stop invocations" was merged
    differently upstream. The original issue where a slow box could lock up
    with a pending timer remained. I currently assume that this is a RT only
    issue and keep the patch as RT only.
