This is a cosmetic patch only. Comparison of the resulting binary showed
only line number differences.
This patch does not affect the generation of the Linux binary.
This patch decreases 210 lines of 20121018 divergence.diff.
The ACPICA source codes uses a totally different indentation style from the
Linux to be compatible with other users (operating systems or BIOS).
Indentation differences are critical to the release automation. There are
two causes related to the "indentation" that are affecting the release
automation:
1. The ACPICA -> Linux release process is:
ACPICA source -- acpisrc - hierarchy - indent ->
linuxized ACPICA source -- diff ->
linuxized ACPICA patch (x) -- human intervention ->
linuxized ACPICA patch (o)
Where
'x' means "cannot be directly applied to the Linux"
'o' means "can be directly applied to the Linux"
Different "indent" version or "indent" options used in the "indent"
step will lead to different divergences.
The version of "indent" used for the current release process is:
GNU indent 2.2.11
The options of "indent" used for the current release process is:
-npro -kr -i8 -ts8 -sob -l80 -ss -ncs
2. Manual indentation prettifying work in the Linux side will also harm the
automatically generated linuxized ACPICA patches, making them impossible
to apply directly.
This patch fixes source code differences caused by the two causes so that
the "human intervention" can be reduced in the future.

All ACPICA locks are allocated by the same function,
acpi_os_create_lock(), with the help of a local variable called
"lock". Thus, when lockdep is enabled, it uses "lock" as the
name of all those locks and regards them as instances of the same
lock, which causes it to report possible locking problems with them
when there aren't any.
To work around this problem, define acpi_os_create_lock() as a macro
and make it pass its argument to spin_lock_init(), so that lockdep
uses it as the name of the new lock. Define this macron in a
Linux-specific file, to minimize the resulting modifications of
the OS-independent ACPICA parts.
This change is based on an earlier patch from Andrea Righi and it
addresses a regression from 2.6.39 tracked as

The ACPI_PREEMPTION_POINT() logic was introduced in commit 8bd108d
(ACPICA: add preemption point after each opcode parse). The follow up
commits abe1dfab6, 138d15692, c084ca70 tried to fix the preemption logic
back and forth, but nobody noticed that the usage of
in_atomic_preempt_off() in that context is wrong.
The check which guards the call of cond_resched() is:
if (!in_atomic_preempt_off() && !irqs_disabled())
in_atomic_preempt_off() is not intended for general use as the comment
above the macro definition clearly says:
* Check whether we were atomic before we did preempt_disable():
* (used by the scheduler, *after* releasing the kernel lock)
On a CONFIG_PREEMPT=n kernel the usage of in_atomic_preempt_off() works by
accident, but with CONFIG_PREEMPT=y it's just broken.
The whole purpose of the ACPI_PREEMPTION_POINT() is to reduce the latency
on a CONFIG_PREEMPT=n kernel, so make ACPI_PREEMPTION_POINT() depend on
CONFIG_PREEMPT=n and remove the in_atomic_preempt_off() check.

Implemented a new acpi_spinlock type for the OSL lock
interfaces. This allows the type to be customized to
the host OS for improved efficiency (since a spinlock is
usually a very small object.)
Implemented support for "ignored" bits in the ACPI
registers. According to the ACPI specification, these
bits should be preserved when writing the registers via
a read/modify/write cycle. There are 3 bits preserved
in this manner: PM1_CONTROL[0] (SCI_EN), PM1_CONTROL[9],
and PM1_STATUS[11].
http://bugzilla.kernel.org/show_bug.cgi?id=3691
Implemented the initial deployment of new OSL mutex
interfaces. Since some host operating systems have
separate mutex and semaphore objects, this feature was
requested. The base code now uses mutexes (and the new
mutex interfaces) wherever a binary semaphore was used
previously. However, for the current release, the mutex
interfaces are defined as macros to map them to the
existing semaphore interfaces.
Fixed several problems with the support for the control
method SyncLevel parameter. The SyncLevel now works
according to the ACPI specification and in concert with the
Mutex SyncLevel parameter, since the current SyncLevel is
a property of the executing thread. Mutual exclusion for
control methods is now implemented with a mutex instead
of a semaphore.
Fixed three instances of the use of the C shift operator
in the bitfield support code (exfldio.c) to avoid the use
of a shift value larger than the target data width. The
behavior of C compilers is undefined in this case and can
cause unpredictable results, and therefore the case must
be detected and avoided. (Fiodor Suietov)
Added an info message whenever an SSDT or OEM table

Removed a device initialization optimization introduced in
20051216 where the _STA method was not run unless an _INI
was also present for the same device. This optimization
could cause problems because it could allow _INI methods
to be run within a not-present device subtree (If a
not-present device had no _INI, _STA would not be run,
the not-present status would not be discovered, and the
children of the device would be incorrectly traversed.)
Implemented a new _STA optimization where namespace
subtrees that do not contain _INI are identified and
ignored during device initialization. Selectively running
_STA can significantly improve boot time on large machines
(with assistance from Len Brown.)
Implemented support for the device initialization case
where the returned _STA flags indicate a device not-present
but functioning. In this case, _INI is not run, but the
device children are examined for presence, as per the
ACPI specification.
Implemented an additional change to the IndexField support
in order to conform to MS behavior. The value written to
the Index Register is not simply a byte offset, it is a
byte offset in units of the access width of the parent
Index Field. (Fiodor Suietov)
Defined and deployed a new OSL interface,
acpi_os_validate_address(). This interface is called during
the creation of all AML operation regions, and allows
the host OS to exert control over what addresses it will
allow the AML code to access. Operation Regions whose
addresses are disallowed will cause a runtime exception
when they are actually accessed (will not affect or abort
table loading.)
Defined and deployed a new OSL interface,
acpi_os_validate_interface(). This interface allows the host OS
to match the various "optional" interface/behavior strings
for the _OSI predefined control method as appropriate
(with assistance from Bjorn Helgaas.)
Restructured and corrected various problems in the
exception handling code paths within DsCallControlMethod
and DsTerminateControlMethod in dsmethod (with assistance
from Takayoshi Kochi.)

literals while converting identifiers from mixed to lower
case. This will correct problems with the disassembler

this would cause the table load to fail, but since
there are several known cases of such tables on
existing machines, this change was made to enable
ACPI support for them. Also, this matches the

Fixed a problem where a null pointer passed to
acpi_ut_delete_generic_state() could be passed through
to acpi_os_release_object which is unexpected. Such
null pointers are now trapped and ignored, matching
the behavior of the previous implementation before the
deployment of acpi_os_release_object(). (Valery Podrezov,

Reorganized the ACPI table header files into two main
files: one for the ACPI tables consumed by the ACPICA core,

Implemented the use of a cache object for all internal
namespace nodes. Since there are about 1000 static nodes
in a typical system, this will decrease memory use for
cache implementations that minimize per-allocation overhead
(such as a slab allocator.)
Removed the reference count mechanism for internal
namespace nodes, since it was deemed unnecessary. This
reduces the size of each namespace node by about 5%-10%
on all platforms. Nodes are now 20 bytes for the 32-bit
case, and 32 bytes for the 64-bit case.
Optimized several internal data structures to reduce
object size on 64-bit platforms by packing data within
the 64-bit alignment. This includes the frequently used
ACPI_OPERAND_OBJECT, of which there can be ~1000 static
instances corresponding to the namespace objects.
Added two new strings for the predefined _OSI method:
"Windows 2001.1 SP1" and "Windows 2006".
Split the allocation tracking mechanism out to a separate
file, from utalloc.c to uttrack.c. This mechanism appears
to be only useful for application-level code. Kernels may

single EndTag. One-length buffers always cause a fatal
exception. Non-zero length buffers that do not end with
a full 2-byte EndTag cause a fatal exception.
Fixed a possible structure overwrite in the
AcpiGetObjectInfo external interface. (With assistance
from Thomas Renninger)

Added 2006 copyright.
At SuSE's suggestion, enabled all error messages
without enabling function tracing, ie with CONFIG_ACPI_DEBUG=n
Replaced all instances of the ACPI_DEBUG_PRINT macro invoked at
the ACPI_DB_ERROR and ACPI_DB_WARN debug levels with
the ACPI_REPORT_ERROR and ACPI_REPORT_WARNING macros,
respectively. This preserves all error and warning messages
in the non-debug version of the ACPICA code (this has been
referred to as the "debug lite" option.) Over 200 cases
were converted to create a total of over 380 error/warning
messages across the ACPICA code. This increases the code
and data size of the default non-debug version by about 13K.
Added ACPI_NO_ERROR_MESSAGES flag to enable deleting all messages.
The size of the debug version remains about the same.
