ARM: PMU: fix runtime PM enable
Commit 7be2958 (ARM: PMU: Add runtime PM Support) updated the ARM PMU code to
use runtime PM which was prototyped and validated on the OMAP devices. In this
commit, there is no call pm_runtime_enable() and for OMAP devices
pm_runtime_enable() is currently being called from the OMAP PMU code when the
PMU device is created. However, there are two problems with this:
1. For any other ARM device wishing to use runtime PM for PMU they will need
to call pm_runtime_enable() for runtime PM to work.
2. When booting with device-tree and using device-tree to create the PMU
device, pm_runtime_enable() needs to be called from within the ARM PERF
driver as we are no longer calling any device specific code to create the
device. Hence, PMU does not work on OMAP devices that use the runtime PM
callbacks when using device-tree to create the PMU device.
Therefore, call pm_runtime_enable() directly from the ARM PMU driver when
registering the device. For platforms that do not use runtime PM,
pm_runtime_enable() does nothing and for platforms that do use runtime PM but
may not require it specifically for PMU, this will just add a little overhead
when initialising and uninitialising the PMU device.
Tested with PERF on OMAP2420, OMAP3430 and OMAP4460.

SERIAL: omap: fix hardware assisted flow control
When the UART device has hardware flow control enabled, it ignores the
MCR RTS bit in the MCR register, and keeps RTS asserted as long as we
continue to read characters from the UART receiver FIFO. This means
that when the TTY buffers become full, the UART doesn't tell the remote
end to stop sending, which causes the TTY layer to start dropping
characters.
A similar problem exists with software flow control. We need the FIFO
register to fill when software flow control is enabled to provoke the
UART to send the XOFF character.
Fix this by implementing the throttle/unthrottle callbacks, and use
these to disable receiver interrupts. This in turn means that the UART
FIFO will fill, which will then cause the UART's hardware to deassert
the RTS signal and/or send the XOFF character, stopping the remote end.

This change makes the SMP_TWD clock .setup()/.stop() pair reentrant
by splitting the .setup() function in three parts:
- One COMMON part that is executed the first time the first CPU
in the TWD cluster is initialized. This will fetch the TWD
clk for the cluster and prepare+enable it. If no clk is
available it will calibrate the rate instead.
- One part that is executed the FIRST TIME a certain CPU is
brought on-line. This initializes and sets up the clock event
for a certain CPU.
- One part that is executed on every subsequent .setup() call.

NFS4: nfs4_opendata_access should return errno
NFSv4: Initialise the NFSv4.1 slot table highest_used_slotid correctly
SUNRPC: return proper errno from backchannel_rqst
NFS: add nfs_sb_deactive_async to avoid deadlock
nfs: Show original device name verbatim in /proc/*/mount{s,info}
nfsv3: Make v3 mounts fail with ETIMEDOUTs instead EIO on mountd timeouts
nfs: Check whether a layout pointer is NULL before free it
NFS: fix bug in legacy DNS resolver.
NFSv4: nfs4_locku_done must release the sequence id
NFSv4.1: We must release the sequence id when we fail to get a session slot
NFS: Wait for session recovery to finish before returning

Merge branch 'release' of git://git.kernel.org/pub/scm/linux/kernel/git/rzhang/linux
Pull thermal management & ACPI update from Zhang Rui,
Ho humm. Normally these things go through Len. But it's just three
small fixes, I guess I can pull directly too.
* 'release' of git://git.kernel.org/pub/scm/linux/kernel/git/rzhang/linux:
exynos4_tmu_driver_ids should be exynos_tmu_driver_ids.
ACPI video: Ignore errors after _DOD evaluation.
thermal: solve compilation errors in rcar_thermal

Merge branch 'i2c-embedded/for-current' of git://git.pengutronix.de/git/wsa/linux
Pull i2c embedded fixes from Wolfram Sang:
"Two patches are usual stuff.
The bigger patch is needed to correct a wrong decision made in this
merge window. We hoped to get the PIOQUEUE mode in the mxs driver
working with DMA, but it turned out to be too broken (leading to data
loss), so we now think it is best to remove it entirely and work only
with DMA now. The patch should be in 3.7. IMO, so users never get
the chance to use both modes in parallel."
* 'i2c-embedded/for-current' of git://git.pengutronix.de/git/wsa/linux:
i2c: tegra: set irq name as device name
i2c-nomadik: Fixup clock handling
i2c: mxs: remove broken PIOQUEUE support
it's slightly bigger than I'd probably like, but nothing looked
dangerous enough to hold off on."
