+	8197981/PR3548 and PR3601 patches AArch32 only
+	as they are now upstream in the new Shenandoah

+	as the Shenandoah versions have been removed.
+	* patches/hotspot/aarch32/pr1748.patch:
+	Replace symlink to Shenandoah version with a
+	regenerated version that applies after JDK-8062808,
+	but without JDK-8036122 being applied as in
+	the Shenandoah version.

+	* patches/hotspot/aarch32/pr3601.patch,
+	* patches/hotspot/aarch32/werror.patch:

+	Regenerated against new context in cppInterpreter_zero.cpp
+	due to JDK-8254166.
