+++ This bug was initially created as a clone of Bug #2074315 +++ Description of problem: https://lore.kernel.org/lkml/164966454348.4207.142052541335966473.tip-bot2@tip-bot2/ genirq/affinity: Consider that CPUs on nodes can be unbalanced If CPUs on a node are offline at boot time, the number of nodes is different when building affinity masks for present cpus and when building affinity masks for possible cpus. This causes the following problem: In the case that the number of vectors is less than the number of nodes there are cases where bits of masks for present cpus are overwritten when building masks for possible cpus. Fix this by excluding CPUs, which are not part of the current build mask (present/possible). Version-Release number of selected component (if applicable): How reproducible: 100%
