[8u-dev] Request for approval for CR JDK-8077276 and CR JDK-8017629

[Andreas Eriksson]

Hi,

I'd like approval for JDK 8 backports of these two largepages fixes.

8077276: allocating heap with UseLargePages and HugeTLBFS may trash 
existing memory mappings (linux)
Bug: https://bugs.openjdk.java.net/browse/JDK-8077276
JDK 9 changeset: http://hg.openjdk.java.net/jdk9/hs/hotspot/rev/98faabe210e9
JDK 9 review thread: 
http://mail.openjdk.java.net/pipermail/hotspot-runtime-dev/2015-April/014442.html
This fix applied cleanly except for minor whitespace differences.

8017629: G1: UseSHM in combination with a G1HeapRegionSize > 
os::large_page_size() falls back to use small pages
Bug: https://bugs.openjdk.java.net/browse/JDK-8017629
