There's a check in make/linux/Makefile to ensure that a 2.4 or later kernel is being used. This has been extended by JDK-7072341 to accommodate Linux 3.x and JDK-8074312 for 4.x. 5.x is now imminent [0] and the build is broken again [1]. Given that 2.4 was released over 18 years ago [2], I think now is the time to just get rid of this check rather than bumping it yet again. If anyone is really trying to build OpenJDK 8 on a 2.2 kernel, I suspect they will encounter other issues than a Makefile check, and it seems far more likely that, if we just add a '5%' check, someone is going to build with Linux 6.x in a few years and hit this same bug again.
