[for-linus][PATCH 1/5] ftrace/x86: Remove possible deadlock between register_kprobe() and ftrace_run_update_code()

From: Petr Mladek The commit 9f255b632bf12c4dd7 ("module: Fix livepatch/ftrace module text permissions race") causes a possible deadlock between register_kprobe() and ftrace_run_update_code() when ftrace is using stop_machine(). The existing dependency chain (in reverse order) is: -> #1

[for-linus][PATCH 2/5] ftrace/x86: Add a comment to why we take text_mutex in ftrace_arch_code_modify_prepare()

From: "Steven Rostedt (VMware)" Taking the text_mutex in ftrace_arch_code_modify_prepare() is to fix a race against module loading and live kernel patching that might try to change the text permissions while ftrace has it as read/write. This really needs to be documented in the code. Add a
