The webrev generally looks good, but I have a few questions and comments 
before this goes back.

Do you know why webrev shows so many files with zero changes?  I assume 
this is an artifact of the merge.

In hotspot_version, what are the semantics of JDK_PREVIOUS_VERSION?

In terms of fixing the %d vs SIZE_FORMAT in vmError.cpp, I've filed 
6929005 "Fix format specifier in vmError.cpp."  However, I notice that 
the JDK 7 master still has %d in this location.  I'll approve going back 
from %d -> SIZE_FORMAT in OpenJDK 6 conditional on the review and 
approval of a HotSpot engineer.

Thanks,
