For EL0 entries requiring bp_hardening, daif status is kept at DAIF_PROCCTX_NOIRQ until after hardening has been done. Then interrupts are enabled through local_irq_enable(). Before using local_irq_* functions, daifflags should be properly restored to a state where IRQs are enabled. Enable IRQs by restoring DAIF_PROCCTX state after bp hardening.
