From: Jan Beulich <redacted> Date: Mon, 19 Feb 2018 07:52:10 -0700 Subject: x86/LDT: Avoid warning in 32-bit builds with older gcc From: Jan Beulich <redacted> commit f2f18b16c779978ece4a04f304a92ff9ac8fbce5 upstream. BUG() doesn't always imply "no return", and hence should be followed by a return statement even if that's obviously (to a human) unreachable.
