From 8b48463f89429af408ff695244dc627e1acff4f7 Mon Sep 17 00:00:00 2001

Subject: ACPI: Clean up inclusions of ACPI header files

Replace direct inclusions of <acpi/acpi.h>, <acpi/acpi_bus.h> and
<acpi/acpi_drivers.h>, which are incorrect, with <linux/acpi.h>
inclusions and remove some inclusions of those files that aren't
necessary.

First of all, <acpi/acpi.h>, <acpi/acpi_bus.h> and <acpi/acpi_drivers.h>
should not be included directly from any files that are built for
CONFIG_ACPI unset, because that generally leads to build warnings about
undefined symbols in !CONFIG_ACPI builds.  For CONFIG_ACPI set,
<linux/acpi.h> includes those files and for CONFIG_ACPI unset it
provides stub ACPI symbols to be used in that case.

Second, there are ordering dependencies between those files that always
have to be met.  Namely, it is required that <acpi/acpi_bus.h> be included
prior to <acpi/acpi_drivers.h> so that the acpi_pci_root declarations the
latter depends on are always there.  And <acpi/acpi.h> which provides
basic ACPICA type declarations should always be included prior to any other
ACPI headers in CONFIG_ACPI builds.  That also is taken care of including
<linux/acpi.h> as appropriate.

Subject: ACPI: Clean up incorrect inclusion of an ACPICA header

Since drivers/acpi/nvs.c includes <linux/acpi.h> and is only compiled
for CONFIG_ACPI set, it doesn't need to include <acpi/acpiosxf.h>
directly, which is formally incorrect.  Remove the <acpi/acpiosxf.h>
inclusion from that file.

Subject: ACPI / i915: Fix incorrect <acpi/acpi.h> inclusions via
 <linux/acpi_io.h>

To avoid build problems and breaking dependencies between ACPI header
files, <acpi/acpi.h> should not be included directly by code outside
of the ACPI core subsystem.  However, that is possible if
<linux/acpi_io.h> is included, because that file contains
a direct inclusion of <acpi/acpi.h>.

For this reason, remove the direct <acpi/acpi.h> inclusion from
<linux/acpi_io.h>, move that file from include/linux/ to include/acpi/
and make <linux/acpi.h> include it for CONFIG_ACPI set along with the
other ACPI header files.  Accordingly, Remove the inclusions of
<linux/acpi_io.h> from everywhere.

Of course, that causes the contents of the new <acpi/acpi_io.h> file
to be available for CONFIG_ACPI set only, so intel_opregion.o that
depends on it should also depend on CONFIG_ACPI (and it really should
not be compiled for CONFIG_ACPI unset anyway).

Subject: ACPI / IBFT: Fix incorrect <acpi/acpi.h> inclusion in iSCSI boot
 firmware module

To avoid build problems and breaking dependencies between ACPI header
files, <acpi/acpi.h> should not be included directly by code outside
of the ACPI core subsystem, but this is done by the ACPI iSCSI
Boot Firmware code.

The iBFT specification doesn't mention whether or not it can appear
on a non-ACPI platform, but is says that ACPI 3.0b defines the
mechanism.  The current CONFIG_ISCSI_IBFT_FIND code doesn't use the
ACPI tables API to locate the table, so it doesn't rely on CONFIG_ACPI
directly.

However, since iBFT is is an ACPI-based mechanism (please refer to
the documentation link below for more information), it should be
correct to make CONFIG_ISCSI_IBFT_FIND depend on CONFIG_ACPI (even
though the table location can be implemented without using ACPI
tables API).

After that change, include/linux/iscsi_ibft.h can be modified to
include <linux/acpi.h> instead of <acpi/acpi.h> as appropriate.

After commit 7f8f97c3cc (ACPI: acpi_table_parse() now returns
success/fail, not count), acpi_table_parse() returns '1' when it is
unable to find the table, but it should return a negative error code
in that case.  Make it return -ENODEV instead.

Fix the same problem in acpi_table_init() analogously.

Subject: ACPI / tables: Return proper error codes from acpi_table_parse() and
 fix comment.

The comment about return value of acpi_table_parse() is incorrect.
This patch fix it.

Since all callers only check if the function succeeded or not, this
patch simplifies the semantics by returning -errno for all failure
cases. This will also simply the comment.

As suggested by Toshi Kani <toshi.kani@hp.com>, also change the stub
in linux/acpi.h to return -ENODEV.
