+Subject: [PATCH 2/2] xtensa: make sure ar_base is initialized
+
+ar_base is uninitialized for cores w/o windowed registers as their
+regmap doesn't have register 0x0100.
+Check that ar_base is initialized and if not initialize it with a0_base.
+
+gdb/
+	* xtensa-tdep.c (xtensa_derive_tdep): Make sure ar_base is
