ACPI table sysfs I/F is broken by commit

ACPI: processor: call _PDC early
because dynamic SSDT tables may be loaded in _PDC,
before installing the ACPI table handler.
As a result, the sysfs I/F of these dynamic tables are
located at /sys/firmware/acpi/tables instead of
/sys/firmware/acpi/tables/dynamic, which is not true.
Invoke acpi_sysfs_init() before acpi_early_processor_set_pdc(),
so that the table handler is installed before any dynamic tables loaded.

ACPI: Page based coalescing of I/O remappings optimization
This patch optimizes ACPI MMIO remappings by keeping track of the
remappings on a PAGE_SIZE granularity.
When an ioremap() occurs, the underlying infrastructure works on a 'page'
based granularity. As such, an ioremap() request for 1 byte for example,
will end up mapping in an entire (PAGE_SIZE) page. Huang Ying took
advantage of this in commit 15651291a2f8c11e7e6a42d8bfde7a213ff13262 by
checking if subsequent ioremap() requests reside within any of the list's
existing remappings still in place, and if so, incrementing a reference
count on the existing mapping as opposed to performing another ioremap().

ACPI: Pre-map 'system event' related register blocks
During ACPI initialization, pre-map fixed hardware registers that are
accessed during ACPI's 'system event' related IRQ handing.
ACPI's 'system event' handing accesses specific fixed hardware
registers; namely PM1a event, PM1b event, GPE0, and GPE1 register
blocks which are declared within the FADT. If these registers are
backed by MMIO, as opposed to I/O port space, accessing them within
interrupt context will cause a panic as acpi_os_read_memory()
depends on ioremap() in such cases - BZ 18012.
By utilizing the functionality provided in the previous two patches -
ACPI: Maintain a list of ACPI memory mapped I/O remappings, and, ACPI:
Add interfaces for ioremapping/iounmapping ACPI registers - accesses
to ACPI MMIO areas will now be safe from within interrupt contexts (IRQ
and/or NMI) provided the area was pre-mapped. This solves BZ 18012.

Author: Myron Stowe <myron.stowe@xxxxxx>
Date: Thu Oct 21 14:23:53 2010 -0600
ACPI: Maintain a list of ACPI memory mapped I/O remappings
For memory mapped I/O (MMIO) remappings, add a list to maintain the
remappings and augment the corresponding mapping and unmapping interface
routines (acpi_os_map_memory() and acpi_os_unmap_memory()) to
dynamically add to, and delete from, the list.
The current ACPI I/O accessing methods - acpi_read() and acpi_write() -
end up calling ioremap() when accessing MMIO. This prevents use of these
methods within interrupt context (IRQ and/or NMI), since ioremap() may
block to allocate memory. Maintaining a list of MMIO remappings enables
accesses to such areas from within interrupt context provided they have
been pre-mapped.

ACPI / Battery: Return -ENODEV for unknown values in get_property()
The function acpi_battery_get_property() is called by the
power supply framework's function power_supply_show_property()
implementing the sysfs interface for power supply devices as the
ACPI battery driver's ->get_property() callback. Thus it is supposed
to return error code if the value of the given property is unknown.
Unfortunately, however, it returns 0 in those cases and puts a
wrong (negative) value into the intval field of the
union power_supply_propval object provided by
power_supply_show_property(). In consequence, wrong negative
values are read by user space from the battery's sysfs files.
Fix this by making acpi_battery_get_property() return -ENODEV
for properties with unknown values (-ENODEV is returned, because
power_supply_uevent() returns with error for any other error code
returned by power_supply_show_property()).

ACPI / PM: Fix reference counting of power resources
The reference counting of ACPI power resources is currently broken
for a few reasons. First, instead of using a simple reference
counter per power resource it uses a list of objects representing
refereces to the given power resource from devices. This leads to
the second breakage, because it prevents power resources from
being referenced more than once by one device, which is necessary
if the device is configured to signal wakeup. Namely, when putting
the device into a low power state we first call
acpi_enable_wakeup_device_power() that should reference count power
resources needed for signaling wakeup and then we call
acpi_power_transition() to power off the device. The latter call
drops references to the device's power resources, possibly including
the ones added by acpi_enable_wakeup_device_power(), so the device
can't signal wakeup as a result. Apart from this, the locking
in acpi_power_on() and acpi_power_off_device() doesn't prevent
all possible races from happening, which may be problematic for
runtime PM and asynchronous suspend and resume.
Fix the problem by using a counter for power resources reference
counting and putting the evaluation of ACPI _ON and _OFF methods
under the power resource mutex.

Subject: [PATCH] ACPICA: Fix Scope() op in module level code
Some Panasonic Toughbooks create nodes in module level code.
Module level code is the executable AML code outside of control method,
for example, below AML code creates a node \_SB.PCI0.GFX0.DD02.CUBL
If (\_OSI ("Windows 2006"))
{
Scope (\_SB.PCI0.GFX0.DD02)
{
Name (CUBL, Ones)
...
}
}
Scope() op does not actually create a new object, it refers to an
existing object(\_SB.PCI0.GFX0.DD02 in above example). However, for
Scope(), we want to indeed open a new scope, so the child nodes(CUBL in
above example) can be created correctly under it.

ACPI battery: support percentage battery remaining capacity
According to the ACPI spec, some kinds of primary battery can
report percentage battery remaining capacity directly to OS.
In this case, it reports the LastFullChargedCapacity == 100,
BatteryPresentRate = 0xFFFFFFFF, and BatteryRemaingCapacity a
percentage value, which actually means RemainingBatteryPercentage.
Now we found some battery follows this rule even if it's a rechargeable.

Handle these batteries correctly in ACPI battery driver
so that they won't break userspace.

ACPI: Make Embedded Controller command timeout delay configurable
Here and then there show up machines which need higher timeout values.
Finding this on affected machines can be cumbersome, because
ACPI_EC_DELAY is a compile option -> make it configurable via boot param.
This can even be provided writable at runtime via:
/sys/modules/acpi/parameters/ec_delay
Known machines where this helps:
Some HP machines where for whatever reasons specific EC accesses take
very long at resume from S3 (in _WAK function).
The AE_TIME error is passed upwards and the ACPI interpreter will
not execute the rest of the _WAK function which results in not properly
initialized devices/variables with different side-effects.
Afaik, on some MSI machines this helped as well.
If this param is needed there probably are underlying problems like:
- EC firmware bug
- A kernel EC driver bug
- An ACPI interpreter behavior (e.g. timings when specific
EC accesses happen and how) which the EC does not like
- ...
which should get evaluated further, but often are nasty or
impossible to fix from OS side.

ACPI dock: move some functions to .init.text
find_dock and find_bay are only called by dock_init which lives in
.init.text dock_add is only called by find_dock and find_bay. So all
three functions can be moved to .init.text, too.
This fixes:

ACPI: delete dedicated MAINTAINERS entries for ACPI EC and BATTERY drivers
We thank Alexey Starikovskiy for his significant contributions

positive impact on the ACPICA core itself.
Alexey is busy with new challenges now, and so we'll take his

ACPI / PM: Fix problems with acpi_pm_device_sleep_state()
There is a number of problems with acpi_pm_device_sleep_state() now.
First, if _S0W is not defined, it prevents devices from being put
into D3 by PCI runtime PM, which shouldn't happen. Second, it
shouldn't use adev->wakeup.state.enabled, because if it's set, it
only means that either the device is permanently enabled to wake up
the system, or that it has been enabled to do that through
/proc/acpi/wakeup. Finally, it should be compiled if CONFIG_PM_SLEEP
is not set, so that PCI runtime PM works correctly in that case.
Fix these problems.

ACPI: Do not export hid/modalias sysfs file for ACPI objects without a HID
Boot and compile tested.
The fact that pnp.ids can now be empty needs testing on some
further machines, though.
This should handle a "modprobe is wrongly called by udev" issue:
https://bugzilla.kernel.org/show_bug.cgi?id=19162
Modaliase files in
/sys/devices/LNXSYSTM:00/
went down from 113 to 71 on my tested system.
This is a sysfs change, but userspace must already be able to handle it.
Also do not fill up pnp.ids list with a "struct hid"
entry. This comment:
* This generic ID isn't useful for driver binding, but it provides
* the useful property that "every acpi_device has an ID."
is still half way true:
Best you never touch pnp.ids list directly or make sure it can be empty,
instead use:
char *acpi_device_hid()
which always returns a value ("device" as a dummy if the object
has no hid).

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.

ACPICA: Revert "Revert "Enable multi-byte EC transfers
This reverts commit f23b9c7(http://git.moblin.org/cgit.cgi/acpica/commit/?id=f23b9c7)
The problem with this change was determined to be a problem with
the FreeBSD host OSL (OS services layer), not with this patch
itself. Therefore, re-introducing this change into the main ACPICA
code. See ACPICA bugzilla 863.

ACPI / ACPICA: Defer enabling of runtime GPEs (v3)
The current ACPI GPEs initialization code has a problem that it
enables some GPEs pointed to by device _PRW methods, generally
intended for signaling wakeup events (system or device wakeup).
These GPEs are then almost immediately disabled by the ACPI namespace
scanning code with the help of acpi_gpe_can_wake(), but it would be
better not to enable them at all until really necessary.
Modify the initialization of GPEs so that the ones that have
associated _Lxx or _Exx methods and are not pointed to by any _PRW
methods will be enabled after the namespace scan is complete.
