ACPICA commit b2294cae776f5a66a7697414b21949d307e6856f

This patch removes unwanted spaces for typedef. This solution doesn't cover
function types.

Note that the linuxize result of this commit is very giant and should have
many conflicts against the current Linux upstream. Thus it is required to
modify the linuxize result of this commit and the commits around it
manually in order to have them merged to the Linux upstream. Since this is
very costy, we should do this only once, and if we can't ensure to do this
only once, we need to revert the Linux code to the wrong indentation result
before merging the linuxize result of this commit. Lv Zheng.

Lv Zheng 8a2a2501a8 ACPICA: Debugger: Fix runtime stub issues of ACPI_DEBUGGER_EXEC using different stub mechanism
ACPICA commit 11522d6b894054fc4d62dd4f9863ec151296b386

The ACPI_DEBUGGER_EXEC is a problem now when the debugger code is compiled
but runtime disabled. They actually will get executed in this situation.
Although such executions are harmless if we can correctly make
acpi_db_single_step() a runtime stub, users may still do not want to see the
debugger print messages logged into OSPMs' kernel logs when a debugger
driver is not loaded to enable the debugger during runtime.

This patch fixes this issue by introducing new stub mechanism instead of
ACPI_DEBUGGER_EXEC. Lv Zheng.

Lv Zheng f8d3148962 ACPICA: Debugger: Convert some mechanisms to OSPM specific
The following mechanisms are OSPM specific:
1. Redirect output destination to console: no file redirection will be
   needed by an in-kernel debugger, there is even no file can be accessed
   when the debugger is running in the kernel mode.
2. Output command prompts: programs other than acpiexec can have different
   prompt characters and the prompt characters may be implemented as a
   special character sequence to form a char device IO protocol.
3. Command ready/complete handshake: OSPM debugger may wait more conditions
   to implement OSPM specific semantics (for example, FIFO full/empty
   conditions for O_NONBLOCK or IO open/close conditions).
Leaving such OSPM specific stuffs in the ACPICA debugger core blocks
Linux debugger IO driver implementation.

Several new OSL APIs are provided by this patch:
1. acpi_os_initialize_command_signals: initialize command handshake mechanism
   or any other OSPM specific stuffs.
2. acpi_os_terminate_command_signals: reversal of
   acpi_os_initialize_command_signals.
3. acpi_os_wait_command_ready: putting debugger task into wait state when a
   command is not ready. OSPMs can terminate command loop by returning
   AE_CTRL_TERMINATE from this API. Normally, wait_event() or
   wait_for_multiple_object() may be used to implement this API.
4. acpi_os_notify_command_complete: putting user task into running state when a
   command has been completed. OSPMs can terminate command loop by
   returning AE_CTRL_TERMINATE from this API. Normally, wake_up() or
   set_event() may be used to implement this API.
This patch also converts current command signaling implementation into a
generic debugger layer (osgendbg.c) to be used by the existing OSPMs or
acpiexec, in return, Linux can have chance to implement its own command
handshake mechanism. This patch also implements acpiexec batch mode in a
multi-threading mode comaptible style as a demo (this can be confirmed by
configuring acpiexec into DEBUGGER_MULTI_THREADED mode where the batch mode
is still working). Lv Zheng.

Note that the OSPM specific command handshake mechanism is required by
Linux kernel because:
1. Linux kernel trends to use wait queue to synchronize two threads, using
   mutexes to achieve that will cause false "dead lock" warnings.
2. The command handshake mechanism implemented by ACPICA is implemented in
   this way because of a design issue in debugger IO streaming. Debugger IO
   outputs are simply cached using a giant buffer, this should be tuned by
   Linux in the future.

Lv Zheng a2352db584 ACPICA: Disassembler: Cleanup acpi_gbl_db_opt_verbose acpiexec usage
ACPICA commit 42d7ad7bfb1cfb95183c1386c77509f2036f521d

When acpi_gbl_db_opt_verbose is used in acpi_dm_descending_op() (invoked by
acpi_dm_disassemble()), it is actually exported by the disassembler but used
by the debugger to distinguish the output of the disassembler for different
debugger commands. It is by default TRUE but is set to FALSE for control
method disassembly command - "disassemble". So it's initialization should
be a part of the ACPI_DISASSEMBLER conditioned code. This patch uses
ACPI_INIT_GLOBAL to achieve a clean manner so that when ACPI_DISASSEMBLER
is not defined, ACPI_DEBUGGER conditioned code needn't link to this option.
Since it is a disassembler exported variable, it is renamed to
acpi_gbl_dm_opt_Verbose in this patch.

As VERBOSE_PRINT() macro has only one user, this patch also removes the
definition of this macro. Lv Zheng.

This patch doesn't affect Linux kernel.

ACPICA commit 7a3f22baab000b186779dac64ad71d9776b8f432

It is likely that the debugger is enabled only when a userspace program
explicitly tells a kernel to do so, so it shouldn't be initialized as
early as current implementation.

The only tool requiring ACPI_DEBUGGER is acpiexec, so acpiexec need to call
the new APIs by itself. And BSD developers may also get notified to invoke
the APIs for DDB enabling. Lv Zheng.

Lv Zheng ab6c573320 ACPICA: Executer: Add interpreter tracing mode for method tracing facility
ACPICA commit 07fffd02607685b655ed92ee15c160e6a810b60b

The acpi_debug_trace() is the mechanism known as ACPI method tracing that is
used by Linux as ACPICA debugging message reducer. This facility can be
controlled through Linux ACPI subsystem - /sys/module/acpi/parameters.
This facility requires CONFIG_ACPI_DEBUG to be enabled to see ACPICA trace
logs in the kernel dmesg output.

This patch enhances acpi_debug_trace() to make it not only a message reducer,
but a real tracer to trace AML interpreter execution. Note that in addition
to the AML tracer enabling, this patch also updates the facility with the
following enhancements:
1. Allow a full path to be specified by the acpi_debug_trace() API.
2. Allow any method rather than just the entrance of acpi_evaluate_object()
   to be traced.
3. All interpreter ACPI_LV_TRACE_POINT messages are collected for
   ACPI_EXECUTER layer.

The Makefile of drivers/acpi/acpica is also updated to include exdebug.o
and the duplicated stubs are removed after that.

Note that since this patch has enhanced the method tracing facility, Linux
need also be updated after applying this patch. Lv Zheng.

Lv Zheng ed6069445d ACPICA: Linuxize: Cleanup spaces after special macro invocations.
This patch reflects the improvment of a cleanup step which is performed in
the release process.

There are still spaces in the "linuxized" ACPICA files after special macro
invocations.  This is because indent treats comments and pre-processor
directives as spaces, thus we need to skip them.

Before applying this patch, cleanup code will search from keyword back to
end of line and wipe spaces between them.

After applying this patch, cleanup code will search to the end of the macro
invocations, skip "empty lines", "comments" and "pre-processor directives",
then wipe the spaces between the new line and the first non-spaces
characters.

Following improvements are thus achieved in the release automation by this

Lv Zheng cd27d79f56 ACPICA: Fix indentation issues for macro invocations.
During the automatic translation of the upstream ACPICA source code
into Linux kernel source code some extra white spaces are added by
the "indent" program at the beginning of each line which is an
invocation of a macro and there is no ";" at the end of the line.

For this reason, a new mode has been added to the translation scripts
to remove the extra spaces inserted before invoking such macros and add
an empty line between the invocations of such macros (like the other
function declarations).  This new mode is executed after executing
"indent" during the Linux release process.  Consequently, some
existing ACPICA source code in the Linux kernel tree needs to be
adjusted to allow the new scripts to work correctly.

The affected macros and files are:
 1. ACPI_HW_DEPENDENT_RETURN (acpixf.h/acdebug.h/acevents.h):
    This macro is used as a wrapper for hardware dependent APIs to offer
    a stub when the reduced hardware is configured during compilation.
 2. ACPI_EXPORT_SYMBOL (utglobal.c):
    This macro is used by Linux to export symbols to be found by Linux
    modules.  All such invocations are well formatted except those
    exported as global variables.

This can help to reduce the source code differences between Linux
and upstream ACPICA, and also help to automate the release process.
No functional or binary generation changes should result from it.
Lv Zheng.

 This change adds full history and limited line editing for Unix and
 Linux systems. It does not use readline() because of portability issues.
 Instead it uses the POSIX termio interface to put the terminal in raw
 input mode so that the various special keys can be trapped (such as
 up-arrow and down-arrow for history support).

Since the debugger is not shipped in the kernel, it only is necessary
to update one header file to keep the kernel source in sync with the
upstream.

Lv Zheng a2fd4b4b4e ACPICA: Add support for host-installed SCI handlers.
This change adds support to allow hosts to install System Control
Interrupt handlers. Certain ACPI functionality requires the host
to handle raw SCIs. For example, the "SCI Doorbell" that is defined
for memory power state support requires the host device driver to
handle SCIs to examine if the doorbell has been activated. Multiple
SCI handlers can be installed to allow for future expansion.
Debugger support is included.
Lv Zheng, Bob Moore. ACPICA BZ 1032.

Bug summary:
It is reported when the PCC (Platform Communication Channel, via
MPST table, defined in ACPI specification 5.0) subchannel responds
to the host, it issues an SCI and the host must probe the subchannel
for channel status.

Lin Ming b0ed7a915a ACPICA/ACPI: Add new host interfaces for _OSI support
Adds install/remove interfaces so that the host can dynamically
alter the global _OSI table. Also adds support for _OSI handlers.
Additional support: new debugger command (osi), and test support in
the acpiexec utility. Adds new file, utilities/utosi.c.
ACPICA bugzilla 836.

The Linux OSL _OSI code is also changed.
acpi_osi_setup can't call acpi_install/remove_interface because ACPICA
is not initialized yet at this early time.
So we just save the osi string in acpi_osi_setup and will handle it
later in a new function acpi_osi_setup_late.
