Subject: [PATCH] acpi: remove nested "ifdef CONFIG_ACPI"
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.
