I've concentrated on the shared code, trusting you guys on the Shenandoah changes.

The only one I'm curious about is the change to
src/os_cpu/linux_zero/vm/atomic_linux_zero.inline.hpp.  There's no
associated bug ID so where does that change come from and is it
specified to the 8u Shenandoah port?

The other shared changes as part of the pacing stats and the
cleanup of what is already a Shenandoah-only class loading
change look ok.

I'll post b05 shortly, and presume you will rebase on top of that as
discussed.

Thanks,
