ACPI / PM: Move ACPI video resume to a PM notifier

There is a problem with the ACPI video resume routine that it's
executed before the GPU that may be accessed by it. To fix this
issue, move the ACPI video resume to a power management notifier,
so that's executed after resuming all devices, including the GPU.

Fixes https://bugzilla.kernel.org/show_bug.cgi?id=15096, which is
a listed regression from 2.6.31.

ACPI: Reduce ACPI resource conflict message to KERN_WARNING, printk cleanup

By default, ACPI resource conflict messages are logged at level
KERN_ERR. This is a rather high level for a message that is more a
warning than an indication of a real kernel error. Also, KERN_ERR level
messages can appear over some boot splash screens, and this message is
not serious enough to warrant such treatment. Thus, the log level has
been reduced to KERN_WARNING.

[lenb changed to KERN_WARNING rather than all the way to KERN_INFO]

Also, cleanup message to use %pR resource printing format.

ACPI: battery drivers should call power_supply_changed()

Calling kobject_uevent() directly is a layering violation. In
particular, it means we'll miss updating the generic LED trigger.

ACPI: battery: Fix CONFIG_ACPI_SYSFS_POWER=n

Disabling CONFIG_ACPI_SYSFS_POWER changes the behaviour of
acpi_battery_update(). It will call acpi_battery_get_info()
even if the battery is not present. I haven't noticed this
causing any problem, but it does look like a bad idea.

PNPACPI: truncate _CRS windows with _LEN > _MAX - _MIN + 1

The ACPI spec (sec 6.4.3.5 in v4.0) requires that for Address Space Resource
Descriptors, _LEN <= _MAX - _MIN + 1 in all cases, but there are BIOSes that
violate this. We experimentally determined that Windows truncates the
resource so it doesn't extend past _MAX, so let's do the same thing in
Linux.

ACPI: Don't send KEY_UNKNOWN for random video notifications

I have a machine here that's sending 0xD1 notifications on the video
device once every second or so. I have no idea why (it's a prototype,
it may be broken), but sending KEY_UNKNOWN is unhelpful and results in
the console becoming unusable. Let's not report keys unless we have
something useful to say about them.

ACPI: NUMA: map pxms to low node ids

pxms are mapped to low node ids to maintain generic kernel use of
functions such as pxm_to_node() that are used to determine device
affinity. Otherwise, there is no pxm-to-node and node-to-pxm matching
rule for x86_64 users of NUMA emulation where a single pxm may be bound
to multiple NUMA nodes.

ACPI: use _HID when supplied by root-level devices

Previously, we assumed the only Device object immediately below the root
was the \_SB Scope (which the ACPI CA treats as a Device), so we forced
the HID of all such objects to ACPI_BUS_HID ("LNXSYBUS").

However, there are DSDTs that supply root-level Device objects with _HIDs.
This patch makes us pay attention to those _HIDs and only add the synthetic
ACPI_BUS_HID for root-level objects that do not supply their own _HID.

For example, this DSDT: https://bugzilla.kernel.org/show_bug.cgi?id=15605
contains:

Scope (_SB) {
...
}
Device (AMW0) {
Name (_HID, EisaId ("PNP0C14"))
...
}

and we should use "PNP0C14" for the AMW0 device, not "LNXSYBUS".

ACPI / ACPICA: Do not check reference counters in acpi_ev_enable_gpe()

acpi_ev_enable_gpe() should enable the GPE at the hardware level
regardless of the value of the GPE's runtime reference counter.

There are only two callers of acpi_ev_enable_gpe(), acpi_enable_gpe()
and acpi_set_gpe(). The first one checks the GPE's runtime
reference counter itself and only calls acpi_ev_enable_gpe() if it's
equal to one, and the other one is supposed to enable the GPE
unconditionally (if called with ACPI_GPE_ENABLE).

This change fixes the problem in acpi_enable_wakeup_device() where
the GPE will not be enabled for wakeup if it's runtime reference
counter is zero, which is a regression from 2.6.33.
