Guo Ren df7f0f8be3 csky: patch_text: Fixup last cpu should be master ... commit 8c4d16471e2babe9bdfe41d6ef724526629696cb upstream. These patch_text implementations are using stop_machine_cpuslocked infrastructure with atomic cpu_count. The original idea: When the master CPU patch_text, the others should wait for it. But current implementation is using the first CPU as master, which couldn't guarantee the remaining CPUs are waiting. This patch changes the last CPU as the master to solve the potential risk.
