arm64: Skip irqflags tracing for NMI in IRQs disabled context
hulk inclusion category: feature bugzilla: 9291 CVE: NA ported from https://lore.kernel.org/patchwork/patch/1037479/ -------------------------------- When an NMI is raised while interrupts where disabled, the IRQ tracing already is in the correct state (i.e. hardirqs_off) and should be left as such when returning to the interrupted context. Check whether PMR was masking interrupts when the NMI was raised and skip IRQ tracing if necessary.
