ACPI: increase PCIBIOS_MIN_IO on x86
since Lukas Sandströ<lukass@etek.chalmers.se> reports that this breaks
his on-board nvidia audio.
We should re-visit this later. For now we revert the change

There are lots of single-PCI-segment machines that don't
supply _SEG for the root bridges. The PCI root bridge driver
silently assumes the segment to be zero in this case,
so glue.c shouldn't complain either.

The video driver doesn't properly remove all the notify handlers
on module unload. This has a side effect of subdevices failing
to register on module reload, but sudden death looms if the
handlers trigger after the module is unloaded.

commit from running until a change has been made in
the destination. In this instance the desired result
was to choose the destination version of the file
and ignore the source version, but git would not
allow that.
Here I added a blank line to let git commit think
I resolved a merge conflict.

If there are devices that use interrupts over a suspend event, ACPI must
restore the PCI interrupt links on resume. Anything else breaks any
device that hasn't been converted to the new (dubious) PM rules.
Drivers that need the irq free/re-aquire sequence can be done one by one
independently of this one.

Implemented support to ignore an attempt to install/load
a particular ACPI table more than once. Apparently there
exists BIOS code that repeatedly attempts to load the same
SSDT upon certain events. Thanks to Venkatesh Pallipadi.
Restructured the main interface to the AML parser in
order to correctly handle all exceptional conditions. This
will prevent leakage of the OwnerId resource and should
eliminate the AE_OWNER_ID_LIMIT exceptions seen on some
machines. Thanks to Alexey Starikovskiy.
Support for "module level code" has been disabled in this
version due to a number of issues that have appeared
on various machines. The support can be enabled by
defining ACPI_ENABLE_MODULE_LEVEL_CODE during subsystem
compilation. When the issues are fully resolved, the code
will be enabled by default again.
Modified the internal functions for debug print support
to define the FunctionName parameter as a (const char *)
for compatibility with compiler built-in macros such as
__FUNCTION__, etc.
Linted the entire ACPICA source tree for both 32-bit
and 64-bit.

EC burst mode benefits many machines, some of
them significantly. However, our current
implementation fails on some machines such
as Rafael's Asus L5D.
This patch restores the alternative EC polling code,
which can be enabled at boot time via "ec_polling"

Now that all of the code paths that call acpi_power_off
have been modified to call either call kernel_power_off
(which calls apci_sleep_prepare by way of acpi_shutdown)
or to call acpi_sleep_prepare directly it is redundant to call
acpi_sleep_prepare from acpi_power_off.
So simplify the code and simply don't call acpi_sleep_prepare.
In addition there is a little error handling done so if we
can't register the acpi class we don't hook pm_power_off.
I think I have done the right thing with the CONFIG_PM define
but I'm not certain. Can this code even be compiled if
CONFIG_PM is false?

machine_power_off on i386 and x86_64 now switch to the
boot cpu out of paranoia and because the MP Specification indicates it
is a good idea on reboot, so for those architectures it is a noop.
I can't see anything in the acpi spec that requires you to be on
the boot cpu to power off the system, so this should not be an issue
for ia64. In addition ia64 has the altix a massive multi-node
system where switching to the boot cpu sounds insane as we may
hot removed the boot cpu.

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.
