The AER error information printing support is implemented in drivers/pci/pcie/aer/aer_print.c. So some string constants, functions and macros definitions can be re-used without being exported. The original PCIe AER error information printing function is not re-used directly because the overall format is quite different. And changing the original printing format may make some original users' scripts broken.
