I looked into the aarch32-jdk9 forest updates. The current goal is to 
update aarch32-jdk9 from jdk9/jdk9 merging at least up to jdk-9+116 tag 
[1] to be able to apply and test aarch32 changes for "better byte 
behaviour" issue.

The first step is to merge aarch32-jdk9 with jdk-9+99 [2]. This tag 
contains two non-trivial hotspot changes:

  - JDK-8132510: Replace ThreadLocalStorage with compiler/language-based 
thread-local variables [3]
  - JDK-8144534: Refactor templateInterpreter and 
templateInterpreterGenerator functions [4]

aarch32 changes for these issues were applied on top of merged jdk-9+99 
tag. Merge is clean for jdk repo, root repo has a minor conflict in a 
non-functional part of generated_configure.sh, hotspot has a conflict in 
threadLocalStorage.hpp that can be resolved the following way (accepting 
mainline changes):

     hg resolve -t internal:other 
src/share/vm/runtime/threadLocalStorage.hpp

Other repositories in aarch32-jdk9 don't require merging - only need to 
be updated to  jdk-9+99 tag.

I'll post corresponding aarch32 changes in separate emails.

Build with these changes is checked to be functional ("java -version" 
works), its testing (self-rebuild) is in progress.
