Hello,

I have completed the upgrade of HHVM from 3.3.1 to 3.6.1 on the continuous integration slaves.

Seems everything is passing just fine now.

== context ==

We upgraded hhvm once but that failed https://phabricator.wikimedia.org/T98876

The main blocker was an issue with a mediawiki/core test that invokes gmp_init(). Stas Malyshev, Giuseppe Lavagetto, Bryan Davis and Ori Livneh all looked at it and found a workaround.
