Commit 906b17dc089f7fa87e37a9cfe6ee185efc90e0da introduced a condition
where the kernel will crash unless a earlyprintk parameter is specified.
Without this parameter, sci_console_init is called during early console
setup without any port being initialized, and the kernel crashes a
little bit later when uart_set_options attemps to invoke set_termios on a
port with an ops member equal to NULL.
This patch just checks in sci_console_init that the port is properly
initialized, and aborts the early console setup if it is not.

The irq numbers of tranfer end and address error are assigned same number
on some CPU. So the sh_dmae_err() should check the AE flag in DMAOR.

We incorrectly returned -EINVAL when none of the devices in the array
had an integrity profile. This in turn prevented mdadm from starting
the metadevice. Fix this so we only return errors on mismatched
profiles and memory allocation failures.

This is what I intended to do since:
1) the driver handles variable waits just fine, and
2) interruptible waits aren't reported as load in the load avg.

Acer WMI hotkey event's result include current device status, just
need sync the status to killswitch after acer-wmi driver receive
hotkey event but not always poll device status. This is good for
performance.
But, if use EC raw mode, Acer BIOS will not emit wmi event and
leave EC to control device status. So, still startup polling job
when doesn't detect WMI event GUID or user choice to use ec_raw_mode.
Tested on Acer TravelMate 8572 notebook.

Acer BIOS keeps devices state when system reboot, but reset to default
device states (Wlan on, Bluetooth off, wwan on) if system cold boot.
That means BIOS's initial state is not always real persistence.
So, removed rfkill_init_sw_state because it sets initial state to
persistence then replicate to other new killswitch when rfkill-input
enabled.
After removed it, acer-wmi set initial soft-block state after rfkill
register, and doesn't allow set_block until rfkill initial finished.

MSI BIOS's raw behavior is send out KEY_TOUCHPAD_TOGGLE key when user
pressed touchpad hotkey.
Actually, we can capture the real touchpad status by read 0xE4 EC address
on MSI netbook/notebook. So, add msi-laptop input device for send out
KEY_TOUCHPAD_ON or KEY_TOUCHPAD_OFF key when user pressed Fn+F3 touchpad
hotkey. It leave userland applications to know the real touchpad status.
Tested on MSI netbook U-100, U-115, U160(N051), U160DX, N014, N034
Tested on MSI notebook CR620

Introduce a new driver for Asus Notebooks shipped with
a WMI device instead of the old ACPI device. The WMI
device is almost the same as the one present in Eee PC,
but the event guid and the keymap are different.
The keymap comes from asus-laptop module.
On Asus notebooks, when you call the WMI device, you always
need a 64bit buffer, even if you only want to get the state
of a device (tested on a G73).

This is tricky, new WMI aware notebooks seems to use
0x53545344 while Eee PCs are using 0x53544344. But there
is no way to know if there is an Eee PC in that wild that is
using 0x53545344 or a notebook using 0x53544344. So the
driver try to guess the available DSTS method ... But most Eee PCs
never return 0xFFFFFFFE when a method is not available, they return
0 instead (and that's useless).
So, first, try 0x53544344 then 0x53545344. We will find
a better way when we got more data.

This patch create a single function to call the
WMI methods. This function handle inexistent methods (when
implemented by the WMI devices, and this is not the case on
Eee PCs), ACPI errors, etc..
Also pack struct bios_arg, and make sure that we always send
a 64bit buffer when calling a WMI method, because this is
needed on Asus notebooks.

New Asus notebooks are using a WMI device similar to
the one used in Eee PCs. Since we don't want to load
eeepc-wmi module on Asus notebooks, and we want to
keep the eeepc-wmi module for backward compatibility,
this patch introduce a new module, named asus-wmi, that
will be used by eeepc-wmi and the new Asus Notebook WMI
Driver.
eeepc-wmi's input device strings (device name and phys)
are kept, but rfkill and led names are changed (s/eeepc/asus/).
This should not break anything since rfkill are used by type or
index, not by name, and the eeepc::touchpad led wasn't working
correctly before 2.6.39 anyway.

New Asus notebooks are using a WMI device similar to
the one used in Eee PCs. Since we don't want to load
a module named eeepc-laptop on Asus Notebooks, start by
copying all the code to asus-wmi.c.

This is the basic thermal sensor driver for Intel MID platform using the
Medfield chipset. It plugs in via the thermal drivers and provides sensor
readings for the device sensors.

hp_wmi_rfkill_setup cleans up after itself now, so failing completely is
no longer necessary.

NULLify rfkill pointers during initialization. This prevents dereference
of invalid pointer in case the driver is rebound and some rfkill device
isn't detected anymore. Clear them also in hp_wmi_rfkill_setup failure
path so that an rfkill initialization failure doesn't need to be fatal
for the whole driver.

Split initialization of rfkill devices from hp_wmi_bios_setup() to
hp_wmi_rfkill_setup(). This makes the code somewhat cleaner, especially
with the future command 0x1b rfkill support.
