John, when you submit patches, you need to add your Signed-off-by!

This patch is not reviewable in context because the messages are not
threaded together - git-send-email does that by default for you.

Alex, have you checked whether the variable can be placed in qom/cpu.c
instead once for all targets? I'd hope that would be possible with an
appropriate typedef (since target_long size etc. are unknown there).
