2012-05-08fork: Provide weak arch_release_[task_struct|thread_info] functionsThomas Gleixner
These functions allow us to move most of the duplicated thread_info allocators to the core code. Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Link: http://lkml.kernel.org/r/20120505150141.366461660@linutronix.de
2012-05-08fork: Move thread info gfp flags to headerThomas Gleixner
These flags can be useful for extra allocations outside of the core code. Add __GFP_NOTRACK to them, so the archs which have kmemcheck do not have to provide extra allocators just for that reason.

2012-05-08regulator: tps62360: fix stylistic issue and optimize codeLaxman Dewangan
Fix multiple stylistic issue like: - The print message should be not break into multiple line. - line gap after variable declaration and statement. - checkpatch error. - some typo. Some enhancement on error message printing to print error value also along with proper text. Avoid voltage_base conversion to microvolts every time. Put init functions in init section. Using efficient function inplace of calling multiple function to reduce the code size.

2012-05-08powerpc: Fix broken cpu_idle_wait() implementationThomas Gleixner
commit 771dae818 (powerpc/cpuidle: Add cpu_idle_wait() to allow switching of idle routines) implemented cpu_idle_wait() for powerpc. The changelog says: "The equivalent routine for x86 is in arch/x86/kernel/process.c but the powerpc implementation is different.": Unfortunately the changelog is completely useless as it does not tell _WHY_ it is different. Aside of being different the implementation is patently wrong. The rescheduling IPI is async. That means that there is no guarantee, that the other cores have executed the IPI when cpu_idle_wait() returns. But that's the whole purpose of this function: to guarantee that no CPU uses the old idle handler anymore. Use the smp_functional_call() based implementation, which fulfils the requirements.

2012-05-08openrisc: use scratch regs in atomic syscallJonas Bonn

2012-05-08openrisc: provide dma_map_opsJonas Bonn
This switches OpenRISC over to fully using the generic dma-mapping framework. This was almost already the case as the architecture's implementation was essentially a copy of the generic header.

2012-05-07netdev/of/phy: Add MDIO bus multiplexer support.David Daney
This patch adds a somewhat generic framework for MDIO bus multiplexers. It is modeled on the I2C multiplexer. The multiplexer is needed if there are multiple PHYs with the same address connected to the same MDIO bus adepter, or if there is insufficient electrical drive capability for all the connected PHY devices. Conceptually it could look something like this: ------------------ | Control Signal | --------+--------- | --------------- --------+------ | MDIO MASTER |---| Multiplexer | --------------- --+-------+---- | | C C h h i i l l d d | | --------- A B --------- | | | | | | | PHY@1 +-------+ +---+ PHY@1 | | | | | | | --------- | | --------- --------- | | --------- | | | | | | | PHY@2 +-------+ +---+ PHY@2 | | | | | --------- --------- This framework configures the bus topology from device tree data. The mechanics of switching the multiplexer is left to device specific drivers. The follow-on patch contains a multiplexer driven by GPIO lines.

2012-05-07netdev/of/phy: New function: of_mdio_find_bus().David Daney
Add of_mdio_find_bus() which allows an mii_bus to be located given its associated the device tree node. This is needed by the follow-on patch to add a driver for MDIO bus multiplexers. The of_mdiobus_register() function is modified so that the device tree node is recorded in the mii_bus. Then we can find it again by iterating over all mdio_bus_class devices. Because the OF device tree has now become an integral part of the kernel, this can live in mdio_bus.c (which contains the needed mdio_bus_class structure) instead of of_mdio.c.

2012-05-07mtd: fix oops in dataflash driverWill Newton
I'm seeing an oops in mtd_dataflash.c with Linux 3.3. What appears to be happening is that otp_select_filemode calls mtd_read_fact_prot_reg with -1 for offset and length and a NULL buffer to test if OTP operations are supported. This finds its way down to otp_read in mtd_dataflash.c and causes an oops when memcpying the returned data into the NULL buf. None of the checks in otp_read catches the negative length and offset. Changing the length of the dummy read to 0 prevents the oops.
