Hildner, Christian a6a1e89eda timers: Fix endless looping between cascade() and internal_add_timer() ... commit 26cff4e2aa upstream. Adding two (or more) timers with large values for "expires" (they have to reside within tv5 in the same list) leads to endless looping between cascade() and internal_add_timer() in case CONFIG_BASE_SMALL is one and jiffies are crossing the value 1 << 18. The bug was introduced between 2.6.11 and 2.6.12 (and survived for quite some time). This patch ensures that when cascade() is called timers within tv5 are not added endlessly to their own list again, instead they are added to the next lower tv level tv4 (as expected).
