From 7694f5143bbe2e2d08216eaee7c62c9d39252889 Mon Sep 17 00:00:00 2001 From: Christian Brauner Date: Tue, 12 May 2020 19:15:27 +0200 Subject: sparc: unconditionally enable HAVE_COPY_THREAD_TLS Now that both sparc and sparc64 support copy_thread_tls() and don't rely on do_fork() anymore, turn on HAVE_COPY_THREAD_TLS unconditionally. Once all architectures are switched over this macro will be removed and the old do_fork() calling convention fully abandoned in favor of the cleaner struct kernel_clone_args one.
