Sort the AP : list to prioritize inactive and pending IRQs, potentially spilling : active IRQs outside of the LRs. : : Handle deactivation of IRQs outside of the LRs for both EOImode=0/1, : which involves special consideration for SPIs being deactivated from a : different vCPU than the one that acked it.
