2009-06-15hwmon: (f71882fg) Add support for the F71858FHans de Goede
Add support for the hwmon part of the Fintek F71858FG superio IC to the f71882fg driver. Many thanks to Jelle de Jong for lending me a motherboard with this superio on it. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Jean Delvare <khali@linux-fr.org>
2009-06-15hwmon: (f71882fg) Add temp#_fault sysfs attr for f8000Hans de Goede
While working on f71852fg support I noticed that the f8000 sysfs attr table was missing entries for temp#_fault, which the f8000 does have and which we were already reading. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Jean Delvare <khali@linux-fr.org>
2009-06-15hwmon: (f71882fg) Sanity check f8000 pwm settingsHans de Goede
We depend up on the pwm_enable register (0x96) not containing any reserved settings in various places. We were already checking to make sure there were no reserved settings in the register for the f71862fg, this patch adds the same checking for the f8000, while at it it also moves the code to a more apropriate place so we don't need to check if the fan/pwm part of the IC is enabled twice.

2009-06-15hwmon: (f71882fg) Cleanup f8000 pwm handlingHans de Goede
Currently we are using separate per model sysfs attr for the 3th pwm, because the 3th pwm of the f8000 only has automatic mode and not manual mode. Doing things this way was getting in the way for adding f71858fg support, so this patch makes the pwm attr identical for all models, and instead adds a check to store_pwm_enable() disallowing setting the 3th pwm to manual mode on a f8000 IC.

2009-06-15hwmon: PCI quirk for hwmon access on MSI MS-7031 boardJean Delvare
The MSI MS-7031 is based on an ATI IXP300 south bridge. On this south bridge, accessible I/O ports must be enabled explicitly. Unfortunately the BIOS forgets to enable access to the hardware monitoring chip I/O ports, so hardware monitoring fails. Add a quirk enabling access to the required ports (0x295-0x296). This is exactly what MSI's own hardware monitoring application is doing, so it has to be the right way. Signed-off-by: Jean Delvare <khali@linux-fr.org>
2009-06-15hwmon: (w83627ehf) Add W83627DHG-P supportJean Delvare
Add support for the new incarnation of the Winbond/Nuvoton W83627DHG chip known as W83627DHG-P. It is basically the same as the original W83627DHG with an additional automatic can speed control mode (not supported by the driver yet.)

2009-06-15hwmon: (tmp401) Add support for TI's TMP401 sensor chipHans de Goede
This is a new hwmon driver for TI's TMP401 temperature sensor IC. This driver was written on behalf of an embedded systems vendor under the Linux driver project.

2009-06-15i2c: Do not probe for TV chips on Voodoo3 adaptersJean Delvare
There's no point in giving the I2C bus of Voodoo3 adapters a class value, there's no video chip driver checking for it anymore. If support is ever needed, the video device should be instantiated explicitly rather than probed.

2009-06-15signal: fix __send_signal() false positive kmemcheck warningVegard Nossum
This false positive is due to field padding in struct sigqueue. When this dynamically allocated structure is copied to the stack (in arch- specific delivery code), kmemcheck sees a read from the padding, which is, naturally, uninitialized. Hide the false positive using the __GFP_NOTRACK_FALSE_POSITIVE flag. Also made the rlimit override code a bit clearer by introducing a new variable.

2009-06-15fs: fix do_mount_root() false positive kmemcheck warningVegard Nossum
This false positive is due to the fact that do_mount_root() fakes a mount option (which is normally read from userspace), and the kernel unconditionally reads a whole page for the mount option. Hide the false positive by using the new __getname_gfp() with the __GFP_NOTRACK_FALSE_POSITIVE flag. Cc: Al Viro <viro@zeniv.linux.org.uk> Signed-off-by: Vegard Nossum <vegard.nossum@gmail.com>
2009-06-15fs: introduce __getname_gfp()Vegard Nossum
