I fell very sorry for people who reviewed my v2 patch series yesterday at https://lkml.org/lkml/2015/2/12/234 because I didn't provide enough information in commit log. This v3 patch series add those missing commit messages. There are also 2 small fix based on v2:
1. Fixes ftrace_sort_mcount_area. Original patch doesn't work for module. 2. Wraps setting of kprobes_initialized in stop_machine() context.
Wang Nan (26): kprobes: set kprobes_all_disarmed earlier to enable re-optimization. kprobes: makes kprobes/enabled works correctly for optimized kprobes. kprobes: x86: mark 2 bytes NOP as boostable. ftrace: don't update record flags if code modification fail. ftrace/x86: Ensure rec->flags no change when failure occures. ftrace: sort ftrace entries earlier. ftrace: allow search ftrace addr before ftrace fully inited. ftrace: enable make ftrace nop before ftrace_init(). ftrace: allow fixing code update failure by notifier chain. ftrace: x86: try to fix ftrace when ftrace_replace_code. early kprobes: introduce kprobe_is_early for futher early kprobe use. early kprobes: Add an KPROBE_FLAG_EARLY for early kprobe. early kprobes: ARM: directly modify code. early kprobes: ARM: introduce early kprobes related code area. early kprobes: x86: directly modify code. early kprobes: x86: introduce early kprobes related code area. early kprobes: introduces macros for allocing early kprobe resources. early kprobes: allows __alloc_insn_slot() from early kprobes slots. early kprobes: perhibit probing at early kprobe reserved area. early kprobes: core logic of eraly kprobes. early kprobes: add CONFIG_EARLY_KPROBES option. early kprobes: introduce arch_fix_ftrace_early_kprobe(). early kprobes: x86: arch_restore_optimized_kprobe(). early kprobes: core logic to support early kprobe on ftrace. early kprobes: introduce kconfig option to support early kprobe on ftrace. kprobes: enable 'ekprobe=' cmdline option for early kprobes.
