+/**
+ Initializes all CPU exceptions entries with optional extra initializations.
+
+ By default, this method should include all functionalities implemented by
+ InitializeCpuExceptionHandlers(), plus extra initialization works, if any.
+ This is could be done by calling InitializeCpuExceptionHandlers() directly
+ in this method besides the extra works.
+
+ InitDataEx is optional and its use and content are processor arch dependent.
+ The typical usage of it is to convey resources which have to be reserved
+ elsewhere and are necessary for the extra initializations of exception.
+
+ @param[in] VectorInfo Pointer to reserved vector list.
+ @param[in] InitDataEx Pointer to data optional for extra initializations
+ of exception.
+
+ @retval EFI_SUCCESS The exceptions have been successfully
+ initialized.
+ @retval EFI_INVALID_PARAMETER VectorInfo or InitDataEx contains invalid
+ content.
+ @retval EFI_UNSUPPORTED This function is not supported.
