Cover letter [PATCH 0/2 v2] x86, Fix irq exhaustion issues with cpu hotplug
These patches have been previously submitted but appear to have been lost on LKML.
There are still some issues with irq exhaustion when removing cpus. These two patches fix two serious bugs. The first patch, from Yinghai Lu, corrects the available vectors count for each cpu. The second patch takes into account the numa-awareness of an irq when reassigning the irq.
