+/**
+  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 could be done by calling InitializeCpuExceptionHandlers() directly
+  in this method besides the extra works.
+
+  InitData 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]  InitData      Pointer to data optional for extra initializations
+                            of exception.
+
+  @retval EFI_SUCCESS             The exceptions have been successfully
+                                  initialized.
+  @retval EFI_INVALID_PARAMETER   VectorInfo or InitData contains invalid
+                                  content.
