2011-03-28ips: use interruptible waits in ips-monitorJesse Barnes1-1/+1
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.

2011-03-28acer-wmi: does not poll device status when WMI event is availableLee, Chun-Yi1-2/+18
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.

2011-03-28acer-wmi: does not set persistence state by rfkill_init_sw_stateLee, Chun-Yi1-5/+14
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.

2011-03-28asus-nb-wmi: Asus Notebooks WMI DriverCorentin Chary4-28/+117
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).

2011-03-28asus-wmi: try to guess the right DSTS methodsCorentin Chary1-33/+66
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. Signed-off-by: Corentin Chary <[email protected]> Signed-off-by: Matthew Garrett <[email protected]>

2011-03-28eeepc-wmi: asus generic asus-wmi.ko moduleCorentin Chary6-498/+681
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.

Existing callers are changed to use the same value for insize and outsize to avoid any regressions, with the exception of hp_wmi_set_block where the output buffer is unused and therefore outsize is set to 0 (this change is not seen by BIOS code). The maximum input buffer size is kept at 4 bytes as per struct bios_args. Some commands exist that take longer buffers, but they haven't been implemented.
