I think AArch64 is also broken, can you put the fix for it in your changeset too?

/pool/buildbot/slaves/sobornost/jdkX-hs/build/src/hotspot/cpu/aarch64/macroAssembler_aarch64.cpp:4517:62:
error: ‘class CardTableModRefBS’ has no member named ‘byte_map_base’
     ((CardTableModRefBS*)(Universe::heap()->barrier_set()))->byte_map_base;
                                                              ^~~~~~~~~~~~~
I can give you the fix soon-ish.
