> Enable IRQs by restoring DAIF_PROCCTX state after bp hardening. Is this just for symmetry, or are you going on to add something to the daifflags state that local_irq_* functions won't change? (if so, could you allude to that in the commit message) Either way, Acked-by: James Morse <[email protected]>
