This API does not support PCI Express AER precise errors. I prefer to
have param int message being replaced by union error_src structure as
below to include PCI Express AER precise errors.

union error_src {
	int message;	 		/* This for PCI Error */  
	struct {				/* This for PCI Express
Precise Error */
		int type;   
		unsigned int flags;  
		unsigned int status; 
		struct header_log_regs *log; 

Please let me know what you think?
