As stands 12.x has picked up Justin's change . . .

stable/12 picked up the -r334498 from head:

https://svnweb.freebsd.org/base/stable/12/sys/powerpc/include/vmparam.h?view=log

shows:

Revision 334498 - (view) (download) (annotate) - [select for diffs] 
Modified Fri Jun 1 21:37:20 2018 UTC (5 months, 2 weeks ago) by jhibbits

Increase powerpc64 KVA from ~7.25GB to 32GB

This will let us use much more KVA for ZFS ARC where needed.  This may be
incresed in the future if memory requirements increase.

In turn the releng sequence later picked up the above as well:

https://svnweb.freebsd.org/base/releng/12.0/sys/powerpc/include/vmparam.h?view=log

shows:

- Copy stable/12 at r340462
 to releng/12.0 as part of the 12.0-RELEASE
  cycle.
- Prune svn:mergeinfo from the new branch.
