Shay Drory 0ad02834c2 genirq/irqdesc: Honor caller provided affinity in alloc_desc() ... commit edbbaae42a upstream. Currently, whenever a caller is providing an affinity hint for an interrupt, the allocation code uses it to calculate the node and copies the cpumask into irq_desc::affinity. If the affinity for the interrupt is not marked 'managed' then the startup of the interrupt ignores irq_desc::affinity and uses the system default affinity mask. Prevent this by setting the IRQD_AFFINITY_SET flag for the interrupt in the allocator, which causes irq_setup_affinity() to use irq_desc::affinity on interrupt startup if the mask contains an online CPU.
