+ * Discovered on X99-series.
+ * These platforms have uncore PCI bridges for 4 CPU sockets
+ * present in ACPI despite having none physically.
+ *
+ * Under normal conditions these are disabled depending on
+ * CPU presence in the socket via Processor Bit Mask (PRBM),
+ * but on X99 this code is unused or broken as such bridges
+ * simply do not exist. We fix that by writing 0 to PRBM.
+ *
+ * Doing so is important as starting with macOS 11 IOPCIFamily
+ * will crash as soon as it sees non-existent PCI bridges.
