driver inclusion category: bugfix bugzilla: NA CVE: NA DTS:DTS202107060S2FXIP1300
----------------------------
Currently, affinity_mask is set to a single value. As a result, irqbalance becomes invalid in SUBSET or EXACT mode. To solve this problem, change affinity_mask to a value range. In this way, irqbalance can be performed on the CPU of the NUMA node.
