If anyone has any objections, please let me know. ------------------ From: Victor Shih commit 85dd3af64965c1c0eb7373b340a1b1f7773586b0 upstream. Due to a flaw in the hardware design, the GL9755 replay timer frequently times out when ASPM is enabled. As a result, the warning messages will often appear in the system log when the system accesses the GL9755 PCI config. Therefore, the replay timer timeout must be masked.
