ACPI: Fix acpi_processor_idle and idle= boot parameters interaction
acpi_processor_idle and "idle=" boot parameter interaction is broken.
The problem is that, at boot time acpi driver is checking for "idle=" boot
option and not registering the acpi idle handler. But, when there is a CST
changed callback (typically when switching AC <-> battery or suspend-resume)
there are no checks for boot_option_idle_override and acpi idle handler tries
to get installed with nasty side effects.
With CPU_IDLE configured this issue causes results in a nasty oops on CST
change callback and without CPU_IDLE there is no oops, but boot option
of "idle=" gets ignored and acpi idle handler gets installed.
Change the behavior to not do anything in acpi idle handler when there is a
"idle=" boot option.
Note that the problem is only there when "idle=" boot option is used.

ACPI: thinkpad-acpi: warn once about weird hotkey masks
thinkpad-acpi knows for a while now how to best program the hotkeys by
default, and always enable them by default. Unfortunately, this
information has not filtered down everywhere it needs to, yet. Notably,
old ibm-acpi documentation and most "thinkpad setup guides" will have wrong
information on this area.
Warn the local admin once whenever any of the following patterns are met:
1. Attempts to set hotkey mask to 0xffff (artifact from docs and config
for the old ibm-acpi driver and behaviour). This mask makes no
real-world sense;
2. Attempts to set hotkey mask to 0xffffffff, which means the user is
trying to just have "everything work" without even reading the
documentation, or that we need to get a bug report, because there
is a new thinkpad out there with new exciting hot keys :-)
3. Attempts to set hotkey mask to 0xffffff, which is almost never the
correct way to set up volume and brightness event reporting (and with
the current state-of-the-art, it is known to never be right way to do
it).
The driver will perform any and all requested operations, though,
regardless of any warnings. I hope these warnings can be removed one or
two years from now.

ACPI: thinkpad-acpi: BIOS backlight mode helper (v2.1)
Lenovo ThinkPads with generic ACPI backlight level control can be easily
set to react to keyboard brightness key presses in a more predictable way
than what they do when in "DOS / bootloader" mode after Linux brings
up the ACPI interface.
The switch to the ACPI backlight mode in the firmware is designed to be
safe to use only as an one way trapdoor. One is not to force the firmware
to switch back to "DOS/bootloader" mode except by rebooting. The mode
switch itself is performed by calling any of the ACPI _BCL methods at least
once.
When in ACPI mode, the backlight firmware just issues (standard) events for
the brightness up/down hot key presses along with the non-standard HKEY
events which thinkpad-acpi traps, and doesn't touch the hardware.
thinkpad-acpi will:
1. Place the ThinkPad firmware in ACPI backlight control mode
if one is available
2. Suppress HKEY backlight change notifications by default
to avoid double-reporting when ACPI video is loaded when
the ThinkPad is in ACPI backlight control mode
3. Urge the user to load the ACPI video driver
The user is free to use either the ACPI video driver to get the brightness
key events, or to override the thinkpad-acpi default hotkey mask to get
them from thinkpad-acpi as well (this will result in duplicate events if
ACPI video is loaded, so let's hope distros won't screw this up).
Provided userspace is sane, all should work (and *keep* working), which is
more that can be said about the non-ACPI mode of the new Lenovo ThinkPad
BIOSes when coupled to current userspace and X.org drivers.
Full guidelines for backlight hot key reporting and use of the
thinkpad-acpi backlight interface have been added to the documentation.

PNP: check for conflicts with all resources, not just earlier ones
This patch removes a use of "idx" in pnp_check_port() and similar
functions, in preparation for replacing idx with a pointer to the
resource itself.
I split this out because it changes the behavior slightly: we used
to check for conflicts only with earlier resources, e.g., we checked
resource 2 against resources 0 and 1 but not against 3, 4, etc. Now
we will check against all resources except 2.
Since resources are assigned in ascending order, the old behavior
was probably safe, but I don't like to depend on that ordering.
