The first commit sets up a field variable and spinlock to indicate whether the PCIe bridge is active. The second commit builds upon the first and adds a "die" handler to the driver, which, when invoked, prints out a summary of any pending PCIe errors. The "die" handler is careful not to access any registers unless the bridge is active.
