// 10/21/2000:
//  It is being proposed to modify PDRIVER_EXCPTN_CALLBACK definition for x86 to match
//  the IA64 definition as a function pointer type returning an ERROR_SEVERITY value.
//  This change was created to allow OEM MCA handlers to return information to the HAL 
//  as a hint how to continue the processing of the MCA event.
