From 9fd5a04d8efcbf511286dd36c46fd70a645b167d Mon Sep 17 00:00:00 2001 From: "Eric W. Biederman" Date: Wed, 20 Oct 2021 12:43:48 -0500 Subject: exit: Remove calls of do_exit after noreturn versions of die On nds32, openrisc, s390, sh, and xtensa the function die never returns. Mark die __noreturn so that no one expects die to return. Remove the do_exit calls after die as they will never be reached.
