It's not a regression, it's just new behavior.
"regression" doesn't mean "things changed". It means "something broke".
What broke?
Because if it's some manual page breakage, just fix the manual. That's
what "new behavior" is all about.
There is nothing that says that "MAP_SHARED_VALIDATE" can't work with
just the legacy flags.
Because I'd be worried about your patch breaking some actual new user
of MAP_SHARED_VALIDATE.
Because it's actual *users* of behavior we care about, not some
test-suite or manual pages.
