    css: Ensure PSCI system off/reset is not interrupted · 0498343a
    dp-arm authored 
    

If there is a pending interrupt, it is possible for the AP to come out
of the final WFI before SCP has a chance to act on it.  Prevent this
by disabling the GIC CPU interface before issuing a WFI.

Previously, SCP would not wait on WFI before taking an action but
would shut down the core or system regardless.
