+  Flush a range of  cache lines in the cache coherency domain of the calling
+  CPU.
+
+  Flushes the cache lines specified by Address and Length.  If Address is not aligned 
+  on a cache line boundary, then entire cache line containing Address is flushed.  
+  If Address + Length is not aligned on a cache line boundary, then the entire cache 
+  line containing Address + Length - 1 is flushed.  This function may choose to flush 
+  the entire cache if that is more efficient than flushing the specified range.  If 
+  Length is 0, the no cache lines are flushed.  Address is returned.   
+  This function is only available on IPF.
+
+  If Length is greater than (MAX_ADDRESS - Address + 1), then ASSERT().
+
+  @param  Address The base address of the instruction lines to invalidate. If
+                  the CPU is in a physical addressing mode, then Address is a
+                  physical address. If the CPU is in a virtual addressing mode,
+                  then Address is a virtual address.
+
+  @param  Length  The number of bytes to invalidate from the instruction cache.
+
+  @return Address.
