       "Xen fixes and featrues for 4.12. The main changes are:
      
         - enable building the kernel with Xen support but without enabling
           paravirtualized mode (Vitaly Kuznetsov)
      
         - add a new 9pfs xen frontend driver (Stefano Stabellini)
      
         - simplify Xen's cpuid handling by making use of cpu capabilities
           (Juergen Gross)

      Linus Torvalds authored
      Pull tracing updates from Steven Rostedt:
       "New features for this release:
      
         - Pretty much a full rewrite of the processing of function plugins.
           i.e. echo do_IRQ:stacktrace > set_ftrace_filter
      
         - The rewrite was needed to add plugins to be unique to tracing
           instances. i.e. mkdir instance/foo; cd instances/foo; echo
           do_IRQ:stacktrace > set_ftrace_filter The old way was written very
           hacky. This removes a lot of those hacks.
      
         - New "function-fork" tracing option. When set, pids in the
           set_ftrace_pid will have their children added when the processes
           with their pids listed in the set_ftrace_pid file forks.
      
         - Exposure of "maxactive" for kretprobe in kprobe_events
      
         - Allow for builtin init functions to be traced by the function
           tracer (via the kernel command line). Module init function tracing
           will come in the next release.
      
         - Added more selftests, and have selftests also test in an instance"

      Linus Torvalds authored
      Pull printk updates from Petr Mladek:
      
       - There is a situation when early console is not deregistered because
         the preferred one matches a wrong entry. It caused messages to appear
         twice.
      
         This is the 2nd attempt to fix it. The first one was wrong, see the
         commit c6c7d83b ('Revert "console: don't prefer first registered
         if DT specifies stdout-path"').
      
         The fix is coupled with some small code clean up. Well, the console
         registration code would deserve a big one. We need to think about it.
      
       - Do not lose information about the preemtive context when the console
         semaphore is re-taken.
      
       - Do not block CPU hotplug when someone else is already pushing
         messages to the console.
      
      * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/pmladek/printk:
        printk: fix double printing with earlycon
        printk: rename selected_console -> preferred_console
        printk: fix name/type/scope of preferred_console var
        printk: Correctly handle preemption in console_unlock()
        printk: use console_trylock() in console_cpu_notify()
