I had expected this would be quickly resolved, but as the fix is not yet
heading towards mainline, lets better ensure this regression is tracked:

#regzbot ^introduced 62b95a7b44d1
#regzbot title arm: vfp: random Warning backtraces in calls from
ct_nmi_enter()
#regzbot fix: ARM: vfp: Fix broken softirq handling with instrumentation
enabled
#regzbot ignore-activity

FWIW, latest patchset to fix it afaics is here:

TWIMC: the fix (ARM: 9294/2: vfp: Fix broken softirq handling with
instrumentation enabled) is in linux-next since a few days. And Guenter
stated the problem doesn't happen anymore since -rc3:

https://lore.kernel.org/linux-arm-kernel/629f3d60-3200-6da3-1d84-220d2b9ae1e8@roeck-us.net/

I'll thus remove this issue from the tracking for now to reduce the
noise; hope that's okay for everybody

#regzbot inconclusive: problem vanished, but there is a fix in
linux-next now, too
#regzbot ignore-activity
