2010-10-21panasonic-laptop: Simplify calls to acpi_pcc_retrieve_biosdataJean Delvare1-10/+10
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.

2010-10-21panasonic-laptop: Handle errors properly if they happenJean Delvare1-0/+2
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.

2010-10-21IBM Real-Time "SMI Free" mode driver -v7Vernon Mauery4-1/+380
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.

2010-10-21Move hdaps driver to platform/x86Jean Delvare6-24/+24
The hdaps driver isn't a hardware monitoring driver, so it shouldn't live under driver/hwmon. drivers/platform/x86 seems much more appropriate, as the driver is only useful on x86 laptops.

2010-10-21ideapad: Add param: no_bt_rfkillIke Panhc1-0/+12
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.

2010-10-20virtio: console: Don't block entire guest if host doesn't read dataAmit Shah1-3/+14
If the host is slow in reading data or doesn't read data at all, blocking write calls not only blocked the program that called write() but the entire guest itself. To overcome this, let's not block till the host signals it has given back the virtio ring element we passed it. Instead, send the buffer to the host and return to userspace. This operation then becomes similar to how non-blocking writes work, so let's use the existing code for this path as well. This code change also ensures blocking write calls do get blocked if there's not enough room in the virtio ring as well as they don't return -EAGAIN to userspace.
