Hi all,

  can I have reviews for the backport of "8067469: G1 ignores
AlwaysPreTouch" for 8u60?

It did only apply with minor changes, so I need re-reviews. The problem
is that JDK-8062063 that has been pushed later has already been
backported to 8u.

Note that this change is based on "8067655: Clean up G1 remembered set
oop iteration" which is also out for review, and "8049536:
os::commit_memory on Solaris uses alignment_hint as page size" which
applied cleanly (hence no RFR for that one).

CR:

Original change:
http://hg.openjdk.java.net/jdk9/jdk9/hotspot/rev/d87c2d9c1eb4

Testing: jprt

Thanks,
