Add some safety check for CONFIG_PM around zeus_power_off(). Without
it linking can fail like this:

This function gets only called from scoop_suspend() and scoop_resume() which are
only built in if we have CONFIG_PM set. Make it the same for check_scoop_reg().
This fixes the following warning:

The IRQs for card detect and status change are currently hardcoded in
SA1111 PCMCIA driver, which can be actually obtained from the .irq[]
from 'struct sa1111_dev' to keep it generic.

IRQ_LOCOMO_* are never used elsewhere, remove these definitions. As well
as the cascade of these IRQs. IRQ_LOCOMO_*_BASE changed to IRQ_LOCOMO_*.
IRQ_LOCOMO_LT and IRQ_LOCOMO_SPI are likely to be used in a same way as
IRQ_LOCOMO_KEY.
IRQ_LOCOMO_GPIO and the demultiplex handler should really be living
somewhere else.

It is not necessary and is over-complicated for IRQ_LOCOMO_KEY to
be a cascaded IRQ of IRQ_LOCOMO_KEY_BASE. Removed and introduced
locomokbd_{open,close} for masking/unmasking of the keyboard IRQ.

These IRQ definitions related to LOCOMO are never referenced anywhere,
thus could be safely removed.

Now most (if not all) PXA platforms have been switched to the new MFP
API, it's rather safe to remove these unnecessary pxa_gpio_mode() calls
in pxa2xx-ac97-lib.c now.

* Modification of Kconfig to add the Option
* 1 new file : buffalo-wxl-setup.c
This file is inspired from the db-78xx0-setup.c already present.
The following is done:
- Configure MPP Lines for the plateform (see my patch for MPP)
This is taken from the stock kernel provided by buffalotech (the vendor)
- GigaBit Ethernet
- Sata
- Uart are initiallized in a different way than on the dev board as we
have one core only.
- USB
The kernel has been running for some days now on my plateform.

This patch is composed of two new files :
- mpp.c which is mainly inspired by the same file as in mach-kirkwood
- mpp.h that is written from the documentation provided by Marvell
http://www.marvell.com/products/processors/embedded/discovery_innovation/HW_MV78100_OpenSource.pdf
Moreover, due to some implementation problem, I have
defined some MPPX_UNUSED that offer developers the possibility
to SET MPP to some unused value (such as for Buffalo WXL).
Note: This patch doesn't support MV78200 yet (only 78100 MPP lines have
been written)

Most laptops have keys that are intended to toggle all device state, not
just wifi. These are currently generally mapped to KEY_WLAN. As a result,
rfkill will only kill or enable wifi in response to the key press. This
confuses users and can make it difficult for them to enable bluetooth
and wwan devices.
This patch adds a new keycode, KEY_RFKILL. It indicates that the system
should toggle the state of all rfkillable devices.

633aae2 "Input: i8042 - switch to using dev_pm_ops" removed handling
for PMSG_THAW, since we do not need to do anything during freeze and
thus it was thougt that thaw is not needed as well. However, there is
a period when interrupts are kept off, and if key happens to be pressed
during that time KBC becomes jammed. To avoid the jam we simply need
to poll KBC once during thaw.

Callers (acpi_memhotplug.c, dock.c and others) check for the return
value of acpi_bus_add() and assume a valid device was returned in
case zero was returned.
Thus return -ENODEV if no device was found in acpi_bus_scan and
propagate this through acpi_bus_add and acpi_bus_start.
Also remove a confusing comment in acpiphp_glue.c, acpi_bus_scan
will and cannot invoke if acpi_bus_add returns no valid device.

Since the rewrite of the CPU idle governor in 2.6.32, two laptops have
surfaced where the BIOS advertises a C2 power state, but for some reason
this state is not functioning (as verified in both cases by powertop
before the patch in .32).
The old governor had the accidental behavior that if a non-working state
was chosen too many times, it would end up falling back to C1. The new
governor works differently and this accidental behavior is no longer
there; the result is a high temperature on these two machines.
This patch adds these 2 machines to the DMI table for C state anomalies;
by just not using C2 both these machines are better off (the TSC can be
used instead of the pm timer, giving a performance boost for example).

Commit fe06fba2 (ACPI: dock: add struct dock_station * directly
to platform device data) changed dock_add() to use the
platform_device_register_data() API.
We passed that interface a stack variable, which is kmemdup'ed
and assigned to the device's platform_data pointer.
Unfortunately, whatever random garbage is in the stack variable
gets coped during the kmemdup, and that leads to broken behavior.
Explicitly zero out the structure before passing it to the API.
This fixes the T41 docking button issue:

We broke "acpi=ht" in 2.6.32 by disabling MADT parsing
for acpi=disabled. e5b8fc6ac158f65598f58dba2c0d52ba3b412f52
This also broke systems which invoked acpi=ht via DMI blacklist.
acpi=ht is a really ugly hack,
but restore it for those that still use it.
