eeepc-laptop provides a sysfs interface to read and control what it
calls cpufv. When WMI is enabled, the ACPI interface changes slightly
and becames a write-only control with 3 valid values.Expose cpufv again to allow for user space utils that can extended battery
life noticably and come a little closer to parity with eeepc-laptop.Write-only is OK for most user space apps because read status was
mostly used to prevent unneeded mode changes. Since this same check
to ignore changes to same mode also exists in the DSDT then it was
wasted ACPI call.acpi_osi="!Windows 2009" can be used for get back eeepc-laptop's
read support of cpufv for debugging things such as behaviour
during resume.This patch was tested with EEE PC 1005PE by monitoring powertop output while
writing values of "0", "1", and "2" and by reviewing the decompiled DSDT of
an 1201NL and comparing it to 1005PE's DSDT.Signed-off-by: Chris Bagwell

Added 4 hotkeys using same keymap values as eeepc-latop.
These are mousepad toggle, resolution change, screen off,
and task manager. These were tested on 1005PE and are the
Fn-F3, F4, F7, and F9, respectively.Also, added a new hot key for power toggles (Fn-Space on 1005PE)
and is meant to drive cpufv interface from userspace.Signed-off-by: Chris Bagwell

Function acpi_pcc_retrieve_biosdata is always called with parameters
(pcc, pcc->sinf), so we can drop the second parameter. It was
dangerous to pass the sinf array separately anyway, as its length is
checked as pcc->num_sifr, which pretty much assumed it was pcc->sinf
(or at least had the same size.)This change makes the code slightly more compact and thus marginally
faster.Signed-off-by: Jean Delvare

acpi_pcc_retrieve_biosdata() returns success instead of error if
HKEY.SINF is invalid. Fix this.Furthermore, if acpi_pcc_retrieve_biosdata() returns an error
during device addition, initialization is properly reverted but value
0 is returned, which means success. This would cause a crash when
later using or removing the device, so fix this too.Signed-off-by: Jean Delvare

After a period of RFC for this driver, I think it is ready
for inclusion in the platform-driver-x86 tree, hopefully to
be staged in the next merge window into Linus's tree.--Vernon
------------------------------------------------------------
IBM Real-Time "SMI Free" mode driver
This driver supports the Real-Time Linux (RTL) BIOS feature.
The RTL feature allows non-fatal System Management Interrupts
(SMIs) to be disabled on supported IBM platforms and is
intended to be coupled with a user-space daemon to monitor
the hardware in a way that can be prioritized and scheduled
to better suit the requirements for the system.The Device is presented as a special "_RTL_" table to the OS
in the Extended BIOS Data Area. There is a simple protocol
for entering and exiting the mode at runtime. This driver
creates a simple sysfs interface to allow a simple entry and
exit from RTL mode in the UFI/BIOS.Since the driver is specific to IBM SystemX hardware (x86-
based servers) it only builds on x86 builds. To reduce the
risk of loading on the wrong hardware, the module uses DMI
information and checks a list of servers that are known to
work.Signed-off-by: Vernon Mauery

The hdaps driver isn't a hardware monitoring driver, so it shouldn't
live under driver/hwmon. drivers/platform/x86 seems much more

Add new module parameter that force module not to register bluetooth rfkill.
There is report that saying using this bluetooth rfkill to enable/disable
bluetooth will let bluetooth device initial failed when enable on Lenovo
ideapad S12. Fortunately there is another rfkill registered by bluetooth
driver for S12 and user can shutdown the bluetooth by either bluetooth driver
or HW RF switch.For dual OS user, it may have some trouble that using Linux after turning off
bluetooth with another OS if we do not register bluetooth rfkill at all. So
we will force bluetooth enable when no_bt_rfkill=1.Signed-off-by: Ike Panhc
