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: Vishnu Motghare

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
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

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.

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:
