      * '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.
