In the Linux kernel, the following vulnerability has been resolved:
irqchip/gic-v3-its: Restore quirk probing for ACPI-based systems While
refactoring the way the ITSs are probed, the handling of quirks applicable
to ACPI-based platforms was lost. As a result, systems such as HIP07 lose
their GICv4 functionnality, and some other may even fail to boot, unless
they are configured to boot with DT. Move the enabling of quirks into
its_probe_one(), making it common to all firmware implementations.

Author	Note
	Priority reason: This issue is addressing a regression in how some specific ARM platforms handle interrupts, and does not appear to have a triggerable security impact.
sbeattie	this issue is fixing quirks for specific ARM platforms interrupt handling.
