+SetJump (
+  IN EFI_PEI_TRANSFER_CONTROL_PROTOCOL  *This,
+  IN EFI_JUMP_BUFFER                    *Jump
+  )
+/*++
+
+Routine Description:
+
+  SetJump stores the current register set in the area pointed to
+by "save".  It returns zero.  Subsequent calls to "LongJump" will
+restore the registers and return non-zero to the same location.
+  On entry, r32 contains the pointer to the jmp_buffer
+  
+Arguments:
+  
+  This  - Calling context
+  Jump  - Jump buffer
+
+Returns:
+
+  Status code

+  )
+/*++
+
+Routine Description:
+
+  LongJump initializes the register set to the values saved by a
+previous 'SetJump' and jumps to the return location saved by that
+'SetJump'.  This has the effect of unwinding the stack and returning
+for a second time to the 'SetJump'.
