Yes, please run the testsuite with the three patches applied. This 
should work (famous last words ;)) for the "native" Linux/sparc64 
version of hotspot (if not, I would to curious to learn why). To test 
Linux/sparc64+zero you obviously need the fourth patch applied as well.

Ah, now I think I get it :) This is for the openjdk-9-jre-zero package, 
right? Does the openjdk-9-jre package provide the "native" (using 
template interpreter, C1, C2) version of hotspot if possible?
