      : GICv3 pseudo-NMI fixes from Mark Rutland:
      :
      : "These patches fix a couple of issues with the way GICv3 pseudo-NMIs are
      : handled:
      :
      : * The first patch adds a barrier we missed from NMI handling due to an
      :   oversight.
      :
      : * The second patch refactors some logic around reads from ICC_IAR1_EL1
      :   and adds commentary to explain what's going on.
      :
      : * The third patch descends into madness, reworking gic_handle_irq() to
      :   consistently manage ICC_PMR_EL1 + DAIF and avoid cases where these can
      :   be left in an inconsistent state while softirqs are processed."
