Restrict the usage of the C preprocessor directive enabling large
pages support to the large pages implementation. This cleans up the
code in src/node.cc.

Can you name this e.g. GetLargePagesSupport()? IsLargePagesEnabled() suggests it returns a boolean when it doesn't.

Alternatively, you could just inline it at the call site; there's only one caller.

struct text_region r = FindNodeTextRegion();
if (r.found_text_region == false) {
PrintWarning("failed to find text region");
return -1;
return ENOENT;
}

Can you drop the braces?

@lundibundi @devnexen @bnoordhuis I made the requested changes, and I also made the entire implementation conditional on the preprocessor flag being defined. That is, if the flag is not defined as 1, only LargePagesError() will be defined, and MapStaticCodeToLargePages() will be defined as returning ENOTSUP.

LGTM but I suspect the linter will complain about two long lines.

@bnoordhuis make lint-cpp did not complain when run locally 🤷

OTOH, cerrno must be included unconditionally, I think, because it's not included on some platforms.

This is not part of node-test-pull-request, AFAICT, so I don't know why it's here. How do I get a full-green run if this is not part of node-test-pull-request?

AFAICT the failing test suite was re-run at https://ci.nodejs.org/job/node-test-commit-linux-containered/nodes=ubuntu1804_sharedlibs_shared_x64/18250/, just not updated in the statuses.

Yes, the containered jobs currently only post status on failure which means they don’t get cleared when a subsequent run passes. It’s on my list of things to look at.
