      suspend: cleanup reference to swsusp_pg_dir[] · a6eb84bc
      Rafael J. Wysocki 提交于
      swsusp_pg_dir[] is used for suspend, but not for hibernation.
      clean-up the ifdefs which worked by accident, while implying the opposite.
      Delete the __nosavedata, which also implied the opposite.
      
      Some day we may optimize CONFIG_ACPI_SLEEP to build minimal kernels
      for just hibernate or just suspend but not both,
      but today isn't that day.

      Suspend: Introduce begin() and end() callbacks · c697eece
      Rafael J. Wysocki 提交于
      On ACPI systems the target state set by acpi_pm_set_target() is
      reset by acpi_pm_finish(), but that need not be called if the
      suspend fails.  All platforms that use the .set_target() global
      suspend callback are affected by analogous issues.
      
      For this reason, we need an additional global suspend callback that
      will reset the target state regardless of whether or not the suspend
      is successful.  Also, it is reasonable to rename the .set_target()
      callback, since it will be used for a different purpose on ACPI
      systems (due to ACPI 1.0x code ordering requirements).
      
      Introduce the global suspend callback .end() to be executed at the
      end of the suspend sequence and rename the .set_target() global
      suspend callback to .begin().

      x86: avoid section mismatch involving arch_register_cpu · d9874026
      Alexander van Heukelum 提交于
      Avoid section mismatch involving arch_register_cpu.
      
      Marking arch_register_cpu as __init and removing the export
      for non-hotplug-cpu configurations makes the following warning
      go away:
      
      Section mismatch in reference from the function
      arch_register_cpu() to the function .devinit.text:register_cpu()
      The function  arch_register_cpu() references
      the function __devinit register_cpu().
      This is often because arch_register_cpu lacks a __devinit
      annotation or the annotation of register_cpu is wrong.
      
      The only external user of arch_register_cpu in the tree is
      in drivers/acpi/processor_core.c where it is guarded by
      ACPI_HOTPLUG_CPU (which depends on HOTPLUG_CPU).

      WARNING: arch/x86/kernel/built-in.o(.exit.text+0xf8): Section mismatch in reference from the function msr_exit() to the variable .cpuinit.data:msr_class_cpu_notifier
      WARNING: arch/x86/kernel/built-in.o(.exit.text+0x158): Section mismatch in reference from the function cpuid_exit() to the variable .cpuinit.data:cpuid_class_cpu_notifier
      WARNING: arch/x86/kernel/built-in.o(.exit.text+0x171): Section mismatch in reference from the function microcode_exit() to the variable .cpuinit.data:mc_cpu_notifier
      
      In all three cases there were a function annotated __exit
      that referenced a variable annotated __cpuinitdata.
      
      The fix was to replace the annotation of the notifier
      with __refdata to tell modpost that the reference to
      a _cpuinit function in the notifier are OK.
      The unregister call that references the notifier
      variable will simple delete the function pointer
      so there is no problem ignoring the reference.
      
      Note: This looks like another case where __cpuinit
      has been used as replacement for proper use
      of CONFIG_HOTPLUG_CPU to decide what code are used for
      HOTPLUG_CPU.

      remove_cpu:maps() had a single user: __cpu_disable() so
      mark it static and annotate it with __ref to silence the
      warning from modpost.
      
      _cpu_disable() has a single user in kernel/cpu.c:
       => take_cpu_down()
          which again has a single user in the following call:
          => __stop_machine_run(take_cpu_down, &tcd_param, cpu);
      Here a kthread is created.
      
      So maybe the warning is correct and the right fix is to
      remove the __cpuinitdata annotation of cpu_initialized?
      
      Note: The analysis were disturbed by the fact that we had a variable
            with the same name in cpu/common.c - but this is 32 bit only]

      setup_node_bootmem() makes NODE_DATA cacheline aligned,
      and bootmap is page-aligned.
      
      the patch updates find_e820_area() to make sure we can meet
      the alignment constraints.

      latencytop: Change Kconfig dependency. · aa7d9350
      Heiko Carstens 提交于
      Change latencytop Kconfig entry so it doesn't list the archictectures
      that support it. Instead introduce HAVE_LATENCY_SUPPORT which any
      architecture can set. Should reduce patch conflicts.
