2014-03-03hsr: off by one sanity check in hsr_register_frame_in()Dan Carpenter
This is a sanity check and we never pass invalid values so this patch doesn't change anything. However the node->time_in[] array has HSR_MAX_SLAVE (2) elements and not HSR_MAX_DEV (3). Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2014-03-03drm/i915: vlv: reserve GT power context earlyImre Deak
We reserve the space for the power context in stolen memory at a fixed address from a delayed work. This races with the subsequent driver init/resume code which could allocate something at that address, so the reservation for the power context fails. Reserve the space up-front, so this can't happen. This also adds a missing struct_mutex lock around the stolen allocation, which wasn't taken in the delayed work path.

2014-03-03Thermal: thermal zone governor fixZhang Rui
This patch does a cleanup about the thermal zone govenor, setting and make the following rule. 1. For thermal zone devices that are registered w/o tz->tzp, they can use the default thermal governor only. 2. For thermal zone devices w/ governor name specified in tz->tzp->governor_name, we will use the default govenor if the governor specified is not available at the moment, and update tz->governor when the matched governor is registered. This also fixes a problem that OF registered thermal zones are running with no governor. Signed-off-by: Zhang Rui <rui.zhang@intel.com> Acked-by: Javi Merino <javi.merino@arm.com>

2014-03-03x86_pkg_temp_thermal: Fix the thermal zone typeJean Delvare
The thermal zone type should not include an instance number. Otherwise each zone is considered a different type and the thermal-to-hwmon bridge fails to group them all in a single hwmon device. I also changed the type to "x86_pkg_temp", because "pkg" was too generic, and other thermal drivers use an underscore, not a dash, as a separator. Or maybe "cpu_pkg_temp" would be better?

2014-03-03can: remove CAN FD compatibility for CAN 2.0 socketsOliver Hartkopp
In commit e2d265d3b587 (canfd: add support for CAN FD in CAN_RAW sockets) CAN FD frames with a payload length up to 8 byte are passed to legacy sockets where the CAN FD support was not enabled by the application. After some discussions with developers at a fair this well meant feature leads to confusion as no clean switch for CAN / CAN FD is provided to the application programmer. Additionally a compatibility like this for legacy CAN_RAW sockets requires some compatibility handling for the sending, e.g. make CAN2.0 frames a CAN FD frame with BRS at transmission time (?!?). This will become a mess when people start to develop applications with real CAN FD hardware. This patch reverts the bad compatibility code together with the documentation describing the removed feature.

2014-03-03spi: spi-ath79: fix initial GPIO CS line setupGabor Juhos
The 'ath79_spi_setup_cs' function initializes the chip select line of a given SPI device in order to make sure that the device is inactive. If the SPI_CS_HIGH bit is set for a given device, it means that the CS line of that device is active HIGH so it must be set to LOW initially. In case of GPIO CS lines, the 'ath79_spi_setup_cs' function does the opposite of that due to the wrong GPIO flags. Fix the code to use the correct GPIO flags.

2014-03-02b44: always set duplex mode why phy changesHauke Mehrtens
Without this patch b44_check_phy() was called when the phy called the adjust callback. This method only change the mac duplex mode when the carrier was off. When the phy changed the duplex mode after the carrier was on the mac was not changed. This happened when an external phy was used.

Sleep control and status registers need santity checks as well before ACPI installs acpi_power_off to pm_power_off hook. The checking code in acpi_enter_sleep_state() is too late, we should not allow a not-working pm_power_off function to be hooked up.
