@addaleax Created this backport PR for new Large Pages Support in v10.x release. I followed all the instructions as stated in backporting-to-release-lines.md document. One step I couldn't do is to run node-test-pull-request CI job due to permission issue. Is this step different than default Travis CI job starts with any new PR changes? Any help is appreciated.

@targos PTAL for 10.x

[lundibundi]

LGTM with a question.

[lundibundi]

Is this change intentional? If so why is it not in a separate commit (backporting this 2d4dd10)?

[uttampawar]

@lundibundi It was not intentional. I'll fix this and update the PR.

[uttampawar]

@lundibundi Fixed the accidental deletion of blank line.
