From 6291ad77d7c57dfc52a6a938d1a77ec3ec3ad16c Mon Sep 17 00:00:00 2001 From: Peter Maydell Date: Fri, 28 Jun 2013 14:22:32 +0100 Subject: linux-user: Move cpu_clone_regs() and cpu_set_tls() into linux-user MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The functions cpu_clone_regs() and cpu_set_tls() are not purely CPU related -- they are specific to the TLS ABI for a a particular OS. Move them into the linux-user/ tree where they belong. target-lm32 had entirely unused implementations, since it has no linux-user target; just drop them.
