+        * score/include/rtems/score/protectedheap.h,
+        score/src/pheapallocate.c: Changed base implementation of protected
+        heap allocations to use _Heap_Allocate_aligned_with_boundary().
+	* libcsupport/include/rtems/malloc.h, libcsupport/src/rtems_malloc.c:
+	Check system state. Process deferred frees. Renamed rtems_malloc() in
+	rtems_heap_allocate_aligned_with_boundary().
+        * score/src/pheapallocatealigned.c: Removed file.
+        * score/Makefile.am: Update for removed file.
