KASan uses constructors for initializing redzones for global variables. Globals instrumentation in GCC 4.9.2 produces constructors with priority (.init_array.00099) Currently kernel ignores such constructors. Only constructors with default priority supported (.init_array) This patch adds support for constructors with priorities. For kernel image we put pointers to constructors between __ctors_start/__ctors_end and do_ctors() will call them on start up. For modules we merge .init_array.* sections into resulting .init_array. Module code properly handles constructors in .init_array section.
