Convert code away from ->read_proc/->write_proc interfaces. Switch to
proc_create()/proc_create_data() which make addition of proc entries
reliable wrt NULL ->proc_fops, NULL ->data and so on.Problem with ->read_proc et al is described here commit

Add pnp_acpi_device(pnp_dev), which takes a PNP device and returns the
associated ACPI device (or NULL, if the device is not a PNPACPI device).This allows us to write a PNP driver that can manage both traditional
PNPBIOS and ACPI devices, treating ACPI-only functionality as an optional
extension.Signed-off-by: Bjorn Helgaas

Makes use of skip_spaces() defined in lib/string.c for removing leading
spaces from strings all over the tree.It decreases lib.a code size by 47 bytes and reuses the function tree-wide:
text data bss dec hex filename
64688 584 592 65864 10148 (TOTALS-BEFORE)
64641 584 592 65817 10119 (TOTALS-AFTER)Also, while at it, if we see (*str && isspace(*str)), we can be sure to
remove the first condition (*str) as the second one (isspace(*str)) also
evaluates to 0 whenever *str == 0, making it redundant. In other words,
"a char equals zero is never a space".Julia Lawall tried the semantic patch (http://coccinelle.lip6.fr) below,
and found occurrences of this pattern on 3 more files:

Jesse accidentally applied v1 [1] of the patchset instead of v2 [2]. This
is the diff between v1 and v2.The changes in this patch are:
- tidied vsprintf stack buffer to shrink and compute size more
accurately
- use %pR for decoding and %pr for "raw" (with type and flags) instead
of adding %pRt and %pRf[1] http://lkml.org/lkml/2009/10/6/491

Every acpi_device has at least one ID (if there's no _HID or _CID, we
give it a synthetic or default ID). So there's no longer a need to
check whether an ID exists; we can just use it.Signed-off-by: Bjorn Helgaas
Signed-off-by: Len Brown -
There's no need to treat _HID and _CID differently. Keeping them in
a single list makes code that uses the IDs a little simpler because it
can just traverse the list rather than checking "do we have a HID?",
"do we have any CIDs?"Signed-off-by: Bjorn Helgaas

Completed a major update for the acpi_get_object_info external interface.
Changes include:
- Support for variable, unlimited length HID, UID, and CID strings
- Support Processor objects the same as Devices (HID,UID,CID,ADR,STA, etc.)
- Call the _SxW power methods on behalf of a device object
- Determine if a device is a PCI root bridge
- Change the ACPI_BUFFER parameter to ACPI_DEVICE_INFO.
These changes will require an update to all callers of this interface.
See the ACPICA Programmer Reference for details.Also, update all invocations of acpi_get_object_info interface

Extended Address Space Descriptors are new in ACPI 3.0 and allow the
BIOS to communicate device resource cacheability attributes (write-back,
write-through, uncacheable, etc) to the OS.Previously, PNPACPI ignored these descriptors, so if a BIOS used them,
a device could be responding at addresses the OS doesn't know about.
This patch adds support for these descriptors in _CRS and _PRS. We
don't attempt to encode them for _SRS (just like we don't attempt to
encode the existing 16-, 32-, and 64-bit Address Space Descriptors).Unfortunately, I don't have a way to test this.

"Enable PNPACPI _PSx Support, v3"added a call to acpi_bus_set_power(handle, ACPI_STATE_D3)
to pnpacpi_disable_resource() before the existing call
to evaluate _DIS on the device.This caused suspend to fail on the system in
http://bugzilla.kernel.org/show_bug.cgi?id=13243
because the sanity check to verify we entered _PS3
failed on the serial port.As a work-around, that sanity check can be disabled
system-wide with "acpi.power_nocheck=1"Or perhaps we should just shrug off the _PS3 failure
and carry on with _DIS like we used to -- which is
what this patch does.Signed-off-by: Len Brown

(This is an update to the patch presented earlier in
http://lkml.org/lkml/2008/12/8/284, with new error handling.)This patch sets the power of PnP ACPI devices to D0 when they
are activated and to D3 when they are disabled. The latter is
in correspondence with the ACPI 3.0 specification, whereas the
former is added in order to be able to power up a device after
it has been previously disabled (or when booting up a system).
(As a consequence, the patch makes the PnP ACPI code more ACPI
compliant.)Section 6.2.2 of the ACPI Specification (at least versions 1.0b
and 3.0a) states: "Prior to running this control method [_DIS],
the OS[PM] will have already put the device in the D3 state."
Unfortunately, there is no clear statement as to when to put
a device in the D0 state. :-( Therefore, the patch executes the
method calls as _PS3/_DIS and _SRS/_PS0. What is clear: "If the
device is disabled, _SRS enables the device at the specified
resources." (From the ACPI 3.0a Specification.)The patch fixes a problem with some IBM ThinkPads (at least the
600E and the 600X) where the serial ports have a dedicated
power source that needs to be brought up before the serial port
can be used. Without this patch, the serial port is enabled
but has no power. (In the past, the tpctl utility had to be
utilized to turn on the power, but support for this feature
stopped with version 5.9 as it did not support the more recent
kernel versions.)The error handlers that handle any errors that can occur during
the power up/power down phases return the error codes to the
caller directly. Comments welcome! :-)No regressions were observed on hardware that does not require
this patch.The patch is applied against 2.6.27.x.

According to ACPI spec when the status of some device is not present
but functional, the device is valid and the children of this device
should be enumerated. It means that the device should be added to
linux acpi device tree. But the device driver for this device should not
be loaded.
The detailed info can be found in the section 6.3.7 of ACPI 3.0b spec.
_STA may return bit 0 clear (not present) with bit 3 set (device is
functional). This case is used to indicate a valid device for which no
device driver should be loaded (for example, a bridge device.).
Children of this device may be present and valid. OS should continue
enumeration below a device whose _STA returns this bit combinationhttp://bugzilla.kernel.org/show_bug.cgi?id=3358
