For aarch64, the PPIs format in /proc/interrputs can be parsed and add to interrupt db, and next, the number of interrupts is counted and used to calculate the load. Finally these interrupts maybe scheduled between the NUMA domains. Acctually, the PPIs cannot change aff, and it should not be added to interrupt db. This patch fix it. Add a check before add a interrupt to db, just only reads the irq's aff, and write it back to avoid any impact on the system, According to the result of writing to fitler the irq.
