[ACPI] acpi_register_gsi() can return error
Current acpi_register_gsi() function has no way to indicate errors to its
callers even though acpi_register_gsi() can fail to register gsi because of
some reasons (out of memory, lack of interrupt vectors, incorrect BIOS, and so
on). As a result, caller of acpi_register_gsi() cannot handle the case that
acpi_register_gsi() fails. I think failure of acpi_register_gsi() should be
handled properly.
This series of patches changes acpi_register_gsi() to return negative value on

acpi_register_gsi().
This patch changes the type of return value of acpi_register_gsi() from

ACPICA
20050708 from Bob Moore <robert.moore@intel.com>
The use of the CPU stack in the debug version of the
subsystem has been considerably reduced. Previously, a
debug structure was declared in every function that used
the debug macros. This structure has been removed in
favor of declaring the individual elements as parameters
to the debug functions. This reduces the cumulative stack
use during nested execution of ACPI function calls at the
cost of a small increase in the code size of the debug
version of the subsystem. With assistance from Alexey
Starikovskiy and Len Brown.
Added the ACPI_GET_FUNCTION_NAME macro to enable the
compiler-dependent headers to define a macro that will
return the current function name at runtime (such as
__FUNCTION__ or _func_, etc.) The function name is used
by the debug trace output. If ACPI_GET_FUNCTION_NAME
is not defined in the compiler-dependent header, the
function name is saved on the CPU stack (one pointer per
function.) This mechanism is used because apparently there
exists no standard ANSI-C defined macro that that returns
the function name.
Alexey Starikovskiy redesigned and reimplemented the
"Owner ID" mechanism used to track namespace objects
created/deleted by ACPI tables and control method
execution. A bitmap is now used to allocate and free the
IDs, thus solving the wraparound problem present in the
previous implementation. The size of the namespace node
descriptor was reduced by 2 bytes as a result.
Removed the UINT32_BIT and UINT16_BIT types that were used
for the bitfield flag definitions within the headers for
the predefined ACPI tables. These have been replaced by
UINT8_BIT in order to increase the code portability of
the subsystem. If the use of UINT8 remains a problem,
we may be forced to eliminate bitfields entirely because
of a lack of portability.
Alexey Starikovksiy enhanced the performance of
acpi_ut_update_object_reference. This is a frequently used
function and this improvement increases the performance
of the entire subsystem.
Alexey Starikovskiy fixed several possible memory leaks
and the inverse - premature object deletion.

ACPICA
20050617:
Moved the object cache operations into the OS interface
layer (OSL) to allow the host OS to handle these operations
if desired (for example, the Linux OSL will invoke the
slab allocator). This support is optional; the compile
time define ACPI_USE_LOCAL_CACHE may be used to utilize
the original cache code in the ACPI CA core. The new OSL
interfaces are shown below. See utalloc.c for an example
implementation, and acpiosxf.h for the exact interface
definitions. Thanks to Alexey Starikovskiy.
acpi_os_create_cache
acpi_os_delete_cache
acpi_os_purge_cache
acpi_os_acquire_object
acpi_os_release_object
Modified the interfaces to acpi_os_acquire_lock and
acpi_os_release_lock to return and restore a flags
parameter. This fits better with many OS lock models.
Note: the current execution state (interrupt handler
or not) is no longer passed to these interfaces. If
necessary, the OSL must determine this state by itself, a
simple and fast operation. Thanks to Alexey Starikovskiy.
Fixed a problem in the ACPI table handling where a valid
XSDT was assumed present if the revision of the RSDP
was 2 or greater. According to the ACPI specification,
the XSDT is optional in all cases, and the table manager
therefore now checks for both an RSDP >=2 and a valid
XSDT pointer. Otherwise, the RSDT pointer is used.
Some ACPI 2.0 compliant BIOSs contain only the RSDT.
Fixed an interpreter problem with the Mid() operator in the
case of an input string where the resulting output string
is of zero length. It now correctly returns a valid,
null terminated string object instead of a string object
with a null pointer.
Fixed a problem with the control method argument handling
to allow a store to an Arg object that already contains an
object of type Device. The Device object is now correctly
overwritten. Previously, an error was returned.
ACPICA
20050624:
Modified the new OSL cache interfaces to use ACPI_CACHE_T
as the type for the host-defined cache object. This allows
the OSL implementation to define and type this object in
any manner desired, simplifying the OSL implementation.
For example, ACPI_CACHE_T is defined as kmem_cache_t for
Linux, and should be defined in the OS-specific header
file for other operating systems as required.
Changed the interface to AcpiOsAcquireObject to directly
return the requested object as the function return (instead
of ACPI_STATUS.) This change was made for performance
reasons, since this is the purpose of the interface in the
first place. acpi_os_acquire_object is now similar to the
acpi_os_allocate interface. Thanks to Alexey Starikovskiy.
Modified the initialization sequence in
acpi_initialize_subsystem to call the OSL interface
acpi_osl_initialize first, before any local initialization.
This change was required because the global initialization
now calls OSL interfaces.
Restructured the code base to split some files because
of size and/or because the code logically belonged in a
separate file. New files are listed below.

Implemented support to execute Type 1 and Type 2 AML
opcodes appearing at the module level (not within a control
method.) These opcodes are executed exactly once at the
time the table is loaded. This type of code was legal up
until the release of ACPI 2.0B (2002) and is now supported
within ACPI CA in order to provide backwards compatibility
with earlier BIOS implementations. This eliminates the
"Encountered executable code at module level" warning that
was previously generated upon detection of such code.
Fixed a problem in the interpreter where an AE_NOT_FOUND
exception could inadvertently be generated during the
lookup of namespace objects in the second pass parse of
ACPI tables and control methods. It appears that this
problem could occur during the resolution of forward
references to namespace objects.
Added the ACPI_MUTEX_DEBUG #ifdef to the
acpi_ut_release_mutex function, corresponding to the same
the deadlock detection debug code to be compiled out in
the normal case, improving mutex performance (and overall
subsystem performance) considerably. As suggested by

of a 32-bit ACPI table (Revision < 2). This also affects
the iASL compiler constant folding. (Note: as per below,
the iASL compiler no longer allows 64-bit constants within
32-bit tables.)
Fixed a problem where string and buffer objects with
"static" pointers (pointers to initialization data within
an ACPI table) were not handled consistently. The internal
object copy operation now always copies the data to a newly
allocated buffer, regardless of whether the source object
is static or not.
Fixed a problem with the FromBCD operator where an
implicit result conversion was improperly performed while
storing the result to the target operand. Since this is an
"explicit conversion" operator, the implicit conversion
should never be performed on the output.
Fixed a problem with the CopyObject operator where a copy
to an existing named object did not always completely
overwrite the existing object stored at name. Specifically,

ACPICA
20050408 from Bob Moore
Fixed three cases in the interpreter where an "index"
argument to an ASL function was still (internally) 32
bits instead of the required 64 bits. This was the Index
argument to the Index, Mid, and Match operators.
The "strupr" function is now permanently local
(acpi_ut_strupr), since this is not a POSIX-defined
function and not present in most kernel-level C
libraries. References to the C library strupr function
have been removed from the headers.
Completed the deployment of static
functions/prototypes. All prototypes with the static
attribute have been moved from the headers to the owning
C file.
ACPICA
20050329 from Bob Moore
An error is now generated if an attempt is made to create
a Buffer Field of length zero (A CreateField with a length
operand of zero.)
The interpreter now issues a warning whenever executable
code at the module level is detected during ACPI table
load. This will give some idea of the prevalence of this
type of code.
Implemented support for references to named objects (other
than control methods) within package objects.
Enhanced package object output for the debug
object. Package objects are now completely dumped, showing
all elements.
Enhanced miscellaneous object output for the debug
object. Any object can now be written to the debug object
(for example, a device object can be written, and the type
of the object will be displayed.)
The "static" qualifier has been added to all local
functions across the core subsystem.
The number of "long" lines (> 80 chars) within the source
has been significantly reduced, by about 1/3.
Cleaned up all header files to ensure that all CA/iASL
functions are prototyped (even static functions) and the
formatting is consistent.
Two new header files have been added, acopcode.h and
acnames.h.
Removed several obsolete functions that were no longer
used.

When cfq I/O scheduler is selected, get_request() in __make_request() calls
__cfq_get_queue(). __cfq_get_queue() finds an existing queue (struct
cfq_queue) of the current process for the device and returns it. If it's not
found, __cfq_get_queue() creates and returns a new one if __cfq_get_queue() is
called with __GFP_WAIT flag, or __cfq_get_queue() returns NULL (this means that
get_request() fails) if no __GFP_WAIT flag.
On the other hand, in __make_request(), get_request() is called without
__GFP_WAIT flag at the first time. Thus, the get_request() fails when there is
no existing queue, typically when it's called for the first I/O request of the
process to the device.
Though it will be followed by get_request_wait() for general case,
__make_request() will just end the I/O with an error (EWOULDBLOCK) when the
request was for read-ahead.

The problem is caused by sbp2's use of scsi_host->hostdata[0] to hold a
