The patch looks good (not an official review) except that I don't
understand one detail. Why does MacroAssembler::zero_words include this?


+    RuntimeAddress zero_blocks =
RuntimeAddress(StubRoutines::aarch64::zero_blocks());
+    assert(zero_blocks.target() != NULL, "zero_blocks stub has not been
generated");
+    if (StubRoutines::aarch64::complete()) {
+      trampoline_call(zero_blocks);
+    } else {
+      bl(zero_blocks);
+    }
