From 140c8180eb7c7cbda399f64474788b86db72db32 Mon Sep 17 00:00:00 2001 From: Christian Brauner Date: Sun, 24 May 2020 23:34:20 +0200 Subject: arch: remove HAVE_COPY_THREAD_TLS All architectures support copy_thread_tls() now, so remove the legacy copy_thread() function and the HAVE_COPY_THREAD_TLS config option. Everyone uses the same process creation calling convention based on copy_thread_tls() and struct kernel_clone_args. This will make it easier to maintain the core process creation code under kernel/, simplifies the callpaths and makes the identical for all architectures.

It's a simpler name, and doesn't imply that only tls is copied here. This finishes an outstanding chunk of internal process creation work since we've added clone3().
