If the condition changes between these two tests, the MSR and irq\nsoft-mask state will become corrupted, leading to warnings and possible\ncrashes. For example, if the branch is initially true then false,\nMSR[EE] will be 0 but PACA_IRQ_HARD_DIS clear and EE may not get\nenabled, leading to warnings in irq_64.c."
