      * 'sched/for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip:
        sched: hrtick_enabled() should use cpu_active()
        sched, x86: clean up hrtick implementation
        sched: fix build error, provide partition_sched_domains() unconditionally
        sched: fix warning in inc_rt_tasks() to not declare variable 'rq' if it's not needed
        cpu hotplug: Make cpu_active_map synchronization dependency clear
        cpu hotplug, sched: Introduce cpu_active_map and redo sched domain managment (take 2)
        sched: rework of "prioritize non-migratable tasks over migratable ones"
        sched: reduce stack size in isolated_cpu_setup()
        Revert parts of "ftrace: do not trace scheduler functions"
      
      Fixed up conflicts in include/asm-x86/thread_info.h (due to the
      TIF_SINGLESTEP unification vs TIF_HRTICK_RESCHED removal) and
      kernel/sched_fair.c (due to cpu_active_map vs for_each_cpu_mask_nr()
      introduction).

      i386 syscall audit fast-path · af0575bb
      Roland McGrath authored
      
      
      This adds fast paths for 32-bit syscall entry and exit when
      TIF_SYSCALL_AUDIT is set, but no other kind of syscall tracing.
      These paths does not need to save and restore all registers as
      the general case of tracing does.  Avoiding the iret return path
      when syscall audit is enabled helps performance a lot.

      x86_64: remove bogus optimization in sysret_signal · 15e8f348
      Roland McGrath authored
      
      
      This short-circuit path in sysret_signal looks wrong to me.
      AFAICT, in practice the branch is never taken--and if it were,
      it would go wrong.  To wit, try loading a module whose init
      function does set_thread_flag(TIF_IRET), and see insmod crash
      (presumably with a wrong user stack pointer).
      
      This is because the FIXUP_TOP_OF_STACK work hasn't been done yet
      when we jump around the call to ptregscall_common and get to
      int_with_check--where it expects the user RSP,SS,CS and EFLAGS to
      have been stored by FIXUP_TOP_OF_STACK.
      
      I don't think it's normally possible to get to sysret_signal with no
      _TIF_DO_NOTIFY_MASK bits set anyway, so these two instructions are
      already superfluous.  If it ever did happen, it is harmless to call
      do_notify_resume with nothing for it to do.
