Pull VFS updates from Al Viro,
Misc cleanups all over the place, mainly wrt /proc interfaces (switch
create_proc_entry to proc_create(), get rid of the deprecated
create_proc_read_entry() in favor of using proc_create_data() and
seq_file etc).
7kloc removed.

Supply a function (proc_remove()) to remove a proc entry (and any subtree
rooted there) by proc_dir_entry pointer rather than by name and (optionally)
root dir entry pointer. This allows us to eliminate all remaining pde->name
accesses outside of procfs.

The only part of proc_dir_entry the code outside of fs/proc
really cares about is PDE(inode)->data. Provide a helper
for that; static inline for now, eventually will be moved
to fs/proc, along with the knowledge of struct proc_dir_entry
layout.

points
Commit 4ae46be "Thermal: Introduce thermal_zone_trip_update()"
introduced a regression causing the fan to be always on even when
the system is idle.
My original idea in that commit is that:
- when the current temperature is above the trip point,
keep the fan on, even if the temperature is dropping.
- when the current temperature is below the trip point,
turn on the fan when the temperature is raising,
turn off the fan when the temperature is dropping.
But this is what the code actually does:
- when the current temperature is above the trip point,
the fan keeps on.
- when the current temperature is below the trip point,
the fan is always on because thermal_get_trend()
in driver/acpi/thermal.c returns THERMAL_TREND_RAISING.
Thus the fan keeps running even if the system is idle.
Fix this in drivers/acpi/thermal.c.

acpi_video_bus_get_devices() may fail due to some video output device
doesn't have the _ADR method, and in this case, the error processing
is to simply free the video structure in acpi_video_bus_add(), while
leaving those already registered video output devices in the wild,
which means for some video output device, we have already registered
a backlight interface and installed a notification handler for it.
So it can happen when user is using this system, on hotkey pressing,
the notification handler will send a keycode through a non-existing
input device, causing kernel freeze.
To solve this problem, free all those already registered video output
devices once something goes wrong in acpi_video_bus_get_devices(), so
that no wild backlight interfaces and notification handlers exist.

Commit 53aac44 (ACPI: Store valid ACPI tables passed via early initrd
in reserved memblock areas) introduced acpi_initrd_override() that
passes a wrong value as the second argument to memblock_reserve().
Namely, the second argument of memblock_reserve() is the size of the
region, not the address of the top of it, so make
acpi_initrd_override() pass the size in there as appropriate.

Currently we decide if the _BQC is using index by first setting the
level to maximum, and then check if _BQC returned maximum; if not, we
say it is using index.
This is not true for some buggy systems, where the _BQC method will
always return a constant value(e.g. 0 or 100 for the two broken system)
and thus break the current logic. So this patch tries to enhance the
quirk detect logic for _BQC: we do this by picking a test_level, it can
be the maximum level or the mininum one based on some condition. And we
don't make the assumption that if _BQC returned a value that is not what
we just set, it must be using an index. Instead, we will compare the
value returned from _BQC and if it doesn't match, see if the returned
value is an index. And if still no, clear the capability of _BQC.

Kconfig symbol ACPI_DEBUG_FUNC_TRACE was only used (through its
corresponding macro) in drivers/acpi/acpica/acmacros.h. That macro
was removed from that header in v3.8, with commit
86ff0e508f88eda6e479a897476026055831d2d8 ("ACPICA: Fix unmerged
acmacros.h divergences."), so ACPI_DEBUG_FUNC_TRACE can now be
removed too, as it is unused.

Found problem on system that firmware that could handle pci aer.
Firmware get error reporting after pci injecting error, before os boots.
But after os boots, firmware can not get report anymore, even pci=noaer
is passed.
Root cause: BIOS _OSC has problem with query bit checking.
It turns out that BIOS vendor is copying example code from ACPI Spec.
In ACPI Spec 5.0, page 290:
If (Not(And(CDW1,1))) // Query flag clear?
{ // Disable GPEs for features granted native control.
If (And(CTRL,0x01)) // Hot plug control granted?
{
Store(0,HPCE) // clear the hot plug SCI enable bit
Store(1,HPCS) // clear the hot plug SCI status bit
}
...
}
When Query flag is set, And(CDW1,1) will be 1, Not(1) will return 0xfffffffe.
So it will get into code path that should be for control set only.
BIOS acpi code should be changed to "If (LEqual(And(CDW1,1), 0)))"
Current kernel code is using _OSC query to notify firmware about support
from OS and then use _OSC to set control bits.
During query support, current code is using all possible controls.
So will execute code that should be only for control set stage.
That will have problem when pci=noaer or aer firmware_first is used.
As firmware have that control set for os aer already in query support stage,
but later will not os aer handling.
We should avoid passing all possible controls, just use osc_control_set
instead.
That should workaround BIOS bugs with affected systems on the field
as more bios vendors are copying sample code from ACPI spec.

In particular, this fixes brightness control initialization for all
devices that return index values from _BQC and don't happen to have the
initial index set by the BIOS in their _BCL table. One example for that
is the Dell Inspiron 15R SE (model number 7520).
What happened for those devices is that acpi_init_brightness queried the
initial brightness by calling acpi_video_device_lcd_get_level_current.
This called _BQC, which returned e.g. 13. As _BQC_use_index isn't
determined at this point (and thus has its initial value of 0), the
index isn't converted into the actual level. As '13' isn't present in
the _BCL list, *level is later overwritten with brightness->curr, which
was initialized to max_level (100) before. Later in
acpi_init_brightness, level_old (with the value 100) is used as an index
into the _BCL table, which causes a value outside of the actual table to
be used as input into acpi_video_device_lcd_set_level(). Depending on
the (undefined) value of that location, this call will fail, causing the
brightness control for the device in question not to be enabled.
Fix that by returning the raw value returned by the _BQC call in the
initialization case.

Commit 18a3870 (ACPI / PM: Expose lists of device power resources
to user space) exposed the lists of ACPI power resources associated
with power states of ACPI devices, but it didn't expose the lists
of ACPI wakeup power resources, which also is necessary to get the
full picture of dependencies between ACPI devices and power
resources.
For this reason, for every ACPI device node having a list of ACPI
wakeup power resources associated with it, expose that list to user
space in analogy with commit 18a3870.

Theoretically, in some situations acpi_device_get_power() may return
an incorrect result, because the settings of the power resources
depended on by the device may indicate a power state shallower than
the actual power state of the device.
Say that two devices, A and B, depend on two power resources, X and
Y, in such a way that _PR0 for both A and B list both X and Y and
_PR3 for both A and B list power resource Y alone. Also suppose
that _PS0 and _PS3 are present for both A and B. Then, if devices
A and B are initially in D0, power resources X and Y are initially
"on" and their reference counters are equal to 2. To put device A
into power state D3hot the kernel will decrement the reference
counter of power resource X, but that power resource won't be turned
off, because it is still in use by device B (its reference counter is
equal to 1). Next, _PS3 will be executed for device A. Afterward
the configuration of the power resources will indicate that device
A is in power state D0 (both X and Y are "on"), but in fact it is
in D3hot (because _PS3 has been executed for it).
In that situation, if acpi_device_get_power() is called to get the
power state of device A, it will first execute _PSC for it which
should return 3. That will cause acpi_device_get_power() to run
acpi_power_get_inferred_state() for device A and the resultant power
state will be D0, which is incorrect.
To fix that change acpi_device_get_power() to first execute
acpi_power_get_inferred_state() for the given device (if it
depends on power resources) and to evaluate _PSC for it subsequently,
so that the result inferred from the power resources configuration
can be amended by the _PSC return value.

Found with a network device in QEMU/KVM guest not working anymore.
Bisected to commit c13085e5
ACPICA: Resource Mgr: Prevent infinite loops in resource walks
That commit will check acpi_resource length strictly which causes
acpi_set_current_resources to return failure and IRQ for PCI
devices is not set properly.
Set length for all those TYPE_END_TAG acpi_resources.

For the predefined names that return fully variable-length
packages, allow a zero-length package with no warning, since it
is technically a legal construct (and BIOS writers use it.)

Flags the case where external control methods are unresolved,
meaning that the disassembler had no idea how many arguments to
parse for the method invocation.
