Subject: linux-user/riscv: Create init_main_thread
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=a56cf00bc06a11627ec7b695618532d0d58cf8de;p=thirdparty%2Fqemu.git

linux-user/riscv: Create init_main_thread

Merge init_thread and target_cpu_copy_regs.
There's no point going through a target_pt_regs intermediate.
