If there is noCPU left, the allocated cpumask is ignored and the process is retriedagain. However, if the HK_TYPE_MANAGED_IRQ housekeeping cpumask turnsout not to contain any CPU in that particular node, that will become aninfinite retry loop.  This particular problem was reported by sashiko[1]. This should rarely happen, but we still need to guard against this.\nFix this infinite loop problem by also skipping NUMA node that has nohousekeeping CPU in the inner while loop of init_vp_index(). Also updatethe early abort check to check for the absence of online housekeepingCPUs instead of just the emptiness of the cpumask. As the outer forloop will only be reached if the housekeeping cpumask has at least oneonline CPU, a NUMA node with housekeeping CPUs will eventually be found.\nhttps://www.cve.org/CVERecord?id=CVE-2026-99251https://git.kernel.org/stable/c/b3993f6dc106ff416c7a613c631e1e0af451aed7https://git.kernel.org/stable/c/f561392afb44a8a42c54c1cfd3f33dace0b50537https://git.kernel.org/stable/c/15dd3429f0e76ca071657e480cb7e6ff3a1af730https://git.kernel.org/stable/c/7141331f2d245efc07175802a6bf76badec871edhttps://git.kernel.org/stable/c/95fec47cdbf747b81ab22affd7252dda6050ad0chttps://git.kernel.org/stable/c/32ea0a33e3a0fb7c10c601b43e1b2f6c06a3f5fd#kernel
