Subject: linux-user/openrisc: Create init_main_thread
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=83411d840cfd80d7288ea096d905413754a87c66;p=thirdparty%2Fqemu.git

linux-user/openrisc: Create init_main_thread

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