I applied mentioned aarch32 changes for jdk-9+99, merged the results 
with jdk-9+103 and applied on top if it aarch32-specific changes for 
JDK-8074457 [1] and 4 other patches. The resulting version was tested 
with bootstrap build on multiple dev boards.

I'll post aarch32-specific changes in separate emails.
