    Linus Torvalds authored
    Pull third pile of kernel_execve() patches from Al Viro:
     "The last bits of infrastructure for kernel_thread() et.al., with
      alpha/arm/x86 use of those.  Plus sanitizing the asm glue and
      do_notify_resume() on alpha, fixing the "disabled irq while running
      task_work stuff" breakage there.
    
      At that point the rest of kernel_thread/kernel_execve/sys_execve work
      can be done independently for different architectures.  The only
      pending bits that do depend on having all architectures converted are
      restrictred to fs/* and kernel/* - that'll obviously have to wait for
      the next cycle.
    
      I thought we'd have to wait for all of them done before we start
      eliminating the longjump-style insanity in kernel_execve(), but it
      turned out there's a very simple way to do that without flagday-style
      changes."
    
    * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/signal:
      alpha: switch to saner kernel_execve() semantics
      arm: switch to saner kernel_execve() semantics
      x86, um: convert to saner kernel_execve() semantics
      infrastructure for saner ret_from_kernel_thread semantics
      make sure that kernel_thread() callbacks call do_exit() themselves
      make sure that we always have a return path from kernel_execve()
      ppc: eeh_event should just use kthread_run()
      don't bother with kernel_thread/kernel_execve for launching linuxrc
      alpha: get rid of switch_stack argument of do_work_pending()
      alpha: don't bother passing switch_stack separately from regs
      alpha: take SIGPENDING/NOTIFY_RESUME loop into signal.c
      alpha: simplify TIF_NEED_RESCHED handling
