On MST systems the monitors don't appear when we set the fb up, but plymouth opens the drm device and holds it open while they come up, when plymouth finishes and lastclose gets called we don't do the delayed fb probe, so the monitor never appears on the console. Fix this by moving the delayed checking into the mode restore. v2: Daniel suggested that ->delayed_hotplug is set under the mode_config mutex, so we should check it under that as well, while we are in the area.

At least on two MST devices I've tested with, when they are link training downstream, they are totally unable to handle aux ch msgs, so they defer like nuts. I tried 16, it wasn't enough, 32 seems better. This fixes one Dell 4k monitor and one of the MST hubs. v1.1: fixup comment (Tom). Acked-by:

This patch checks if the process that opens the /dev/kfd device is 32-bit process. If so, it returns -EPERM and prints a warning message in dmesg. This is done to prevent 32-bit user processes from using amdkfd, and hence, HSA features. AMD's HSA userspace stack will also support only 64-bit processes on Linux. Reviewed-by:

Cadence I2C controller has bug wherein it generates invalid read transactions after timeout in master receiver mode. This driver does not use the HW timeout and this interrupt is disabled but the feature itself cannot be disabled. Hence, this patch writes the maximum value (0xFF) to this register. This is one of the workarounds to this bug and it will not avoid the issue completely but reduces the chances of error. Signed-off-by:

According to I2C specification the NACK should be handled as follows: "When SDA remains HIGH during this ninth clock pulse, this is defined as the Not Acknowledge signal. The master can then generate either a STOP condition to abort the transfer, or a repeated START condition to start a new transfer." [I2C spec Rev. 6, 3.1.6: http://www.nxp.com/documents/user_manual/UM10204.pdf] Currently the Davinci i2c driver interrupts the transfer on receipt of a NACK but fails to send a STOP in some situations and so makes the bus stuck until next I2C IP reset (idle/enable). For example, the issue will happen during SMBus read transfer which consists from two i2c messages write command/address and read data: S Slave Address Wr A Command Code A Sr Slave Address Rd A D1..Dn A P <--- write -----------------------> <--- read ---------------------> The I2C client device will send NACK if it can't recognize "Command Code" and it's expected from I2C master to generate STP in this case. But now, Davinci i2C driver will just exit with -EREMOTEIO and STP will not be generated. Hence, fix it by generating Stop condition (STP) always when NACK is received. This patch fixes Davinci I2C in the same way it was done for OMAP I2C commit cda2109a ("i2c: omap: query STP always when NACK is received"). Reviewed-by:

It appears that some SCHEDULE_USER (asm for schedule_user) callers in arch/x86/kernel/entry_64.S are called from RCU kernel context, and schedule_user will return in RCU user context. This causes RCU warnings and possible failures. This is intended to be a minimal fix suitable for 3.18. Reported-and-tested-by:

Pull devicetree bugfix from Grant Likely: "One more bug fix for v3.18. I debated whether or not to send you this merge request because we're at such a late rc. The bug isn't critical in that there is only one system known to be affected and the patch is easy to backport. The codepath is used by pretty much every DT based system, so there is risk a of regression (it /should/ be safe, but I've been bitten by stuff that should be safe before). I've had it in linux-next for a week and haven't received any complaints. I think it probably should just be merged right away rather than waiting for the merge window and backporting. It does fix a real bug and the code is theoretically safer after the change. I can't think of any situation where it would be dangerous to reserve the DT memory an extra time. Summary from tag: Single bugfix for boot failure seen in the wild. The memory reserve code tries to be clever about reserving the FDT, but it should just go ahead and reserve it unconditionally to avoid the problem of partial overlap described in the patch" * tag 'devicetree-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/glikely/linux: of/fdt: memblock_reserve /memreserve/ regions in the case of partial overlap
