In turn, this allows device drivers\u0027 \"late\" suspend and\n\"early\" resume callbacks to sleep, execute ACPI callbacks etc.\n\nThe functions introduced here will be used to rework the handling of\ninterrupts during suspend (hibernation) and resume. Namely,\ninterrupts will only be disabled on the CPU right before suspending\nsysdevs, while device drivers will be prevented from receiving\ninterrupts, with the help of the new helper function, before their\n\"late\" suspend callbacks run (and analogously during resume).\n\nSigned-off-by: Rafael J.
