[PATCH] acpi: remove nested "ifdef CONFIG_ACPI"

["Andreas Herrmann" <andreas.herrmann3@amd.com>]

In include/linux/acpi.h we have following ifdefs:

  #ifndef _LINUX_ACPI_H
  #define _LINUX_ACPI_H


  #ifdef  CONFIG_ACPI    <===

  #ifndef _LINUX
  #define _LINUX
  #endif

  #include <linux/list.h>
  #include <linux/mod_devicetable.h>

  #include <acpi/acpi.h>
  #include <acpi/acpi_bus.h>
  #include <acpi/acpi_drivers.h>
  #include <acpi/acpi_numa.h>
  #include <asm/acpi.h>


  #ifdef CONFIG_ACPI     <===

The nesting of "ifdef CONFIG_ACPI" is kind of interesting.
But I guess this was not intentional.(Or did I miss something?)

Attached is a patch to remove that nesting and to clean up
this header a little bit.


Regards,

Andreas

[PATCH] acpi: remove nested "ifdef CONFIG_ACPI"

 - Remove nested ifdef CONFIG_ACPI which required minor changes of the header.
 - Remove unused function declaration for acpi_paddr_to_node. grep didn't
   find a usage of that function.
