Hello Steve, vendors.

Under certain circumstances software event overflows go wrong and
deadlock. Avoid trying to delete a timer from the timer callback.

https://lkml.org/lkml/2011/7/28/284 (fix)

Upstream fix:
a8b0ca17b80e92faab46ee7179ba9e99ccb61233 (much larger patch that
contains the hunk referenced above)

Use CVE-2011-2918.

Thanks, Eugene
