Currently, the LP55xx DT structure supports max 3 channels.
However, LP5523 has max 9 channels and LP5562 has 4 channels.
To enhance this constraint, the DT structure has been changed.
(a) Use the child node for various channel settings instead of fixed array
(b) Remove 'num_channel' property.
This value can be retrieved by counting the children node.
(c) 'chan-name' property supported
(d) Documentation updates for LP5521 and LP5523

This adds basic support for gate-clocks on Rockchip SoCs.
There are 16 gates in each register and use the HIWORD_MASK
mechanism for changing gate settings.
The gate registers form a continuos block which makes the dt node
structure a matter of taste, as either all 160 gates can be put into
one gate clock spanning all registers or they can be divided into
the 10 individual gates containing 16 clocks each.
The code supports both approaches.

The Nomadik clock implementation was a stub just using
fixed clocks.
This implements the clocks properly instead of relying
on them all being on at boot and leaving them all on.
The PLLs are on the top locking to the main chrystal
oscillator, then the HCLK for the peripherals are
below PLL2.
The gated clocks are implemented with zero cells and
given the clock ID as a property of each node, so every
gate need to have its own node in the device tree.
This is because the gate registers contain both HCLK
gates and PCLK gates, where the latter has HCLK as
parent. As can be seen from the register layout, this
is a complete mixup, which means all these gates need
their own node to properly model parent/child relations
for PCLKs apart from the HCLKs.
This driver also adds a helpful debugfs file to inspect
the hardware state of the clock gates.
This is the end result in <debugfs>/clk/clk_summary
after applying a proper device tree:

VFIO implements platform independent stuff such as
a PCI driver, BAR access (via read/write on a file descriptor
or direct mapping when possible) and IRQ signaling.
The platform dependent part includes IOMMU initialization
and handling. This implements an IOMMU driver for VFIO
which does mapping/unmapping pages for the guest IO and
provides information about DMA window (required by a POWER
guest).

Add a traceoff_on_warning option in both the kernel command line as well
as a sysctl option. When set, any WARN*() function that is hit will cause
the tracing_on variable to be cleared, which disables writing to the
ring buffer.
This is useful especially when tracing a bug with function tracing. When
a warning is hit, the print caused by the warning can flood the trace with
the functions that producing the output for the warning. This can make the
resulting trace useless by either hiding where the bug happened, or worse,
by overflowing the buffer and losing the trace of the bug totally.

b0f1a59a "tracing/filters: Use a different op for glob match" added
glob matching to tracepoint filter strings. It uses the ftrace function
tracing glob matching facility that allows for the wild card character (*)
to be used at the start and/or end of the matching string.
But the documentation still states that the filtering only allows for
exact string matches.

There are some cases when filtering on a set flag of a field of a tracepoint
is useful. But currently the only filtering commands for numbered fields
is ==, !=, <, <=, >, >=. This does not help when you just want to trace if
a specific flag is set. For example:
> # sudo trace-cmd record -e brcmfmac:brcmf_dbg -f 'level & 0x40000'
> disable all
> enable brcmfmac:brcmf_dbg
> path = /sys/kernel/debug/tracing/events/brcmfmac/brcmf_dbg/enable
> (level & 0x40000)
> ^
> parse_error: Invalid operator
>
When trying to trace brcmf_dbg when level has its 1 << 18 bit set, the
filter fails to perform.
By allowing a binary '&' operation, this gives the user the ability to
test a bit.
Note, a binary '|' is not added, as it doesn't make sense as fields must
be compared to constants (for now), and ORing a constant will always return
true.

The ath9k Kconfig conflict was a change of a Kconfig option name right
next to the deletion of another option.
The xen-netback conflict was overlapping changes involving the
handling of the notify list in xen_netbk_rx_action().
Batman conflict resolution provided by Antonio Quartulli, basically
keep everything in both conflict hunks.
The nl80211 conflict is a little more involved. In 'net' we added a
dynamic memory allocation to nl80211_dump_wiphy() to fix a race that
Linus reported. Meanwhile in 'net-next' the handlers were converted
to use pre and post doit handlers which use a flag to determine
whether to hold the RTNL mutex around the operation.
However, the dump handlers to not use this logic. Instead they have
to explicitly do the locking. There were apparent bugs in the
conversion of nl80211_dump_wiphy() in that we were not dropping the
RTNL mutex in all the return paths, and it seems we very much should
be doing so. So I fixed that whilst handling the overlapping changes.
To simplify the initial returns, I take the RTNL mutex after we try
to allocate 'tb'.

To disable spurious interrupts, that get triggered on certain hardware, the
irqpin driver masks them on the parent interrupt controller. To specify
such broken devices a .control_parent parameter can be provided in the
platform data. In the DT case we need a property, to do the same.

Pull RCU changes from Paul E. McKenney:
"The major changes for this series are:
1. Simplify RCU's grace-period and callback processing based on
the new numbering for callbacks. These were posted to LKML at
https://lkml.org/lkml/2013/5/20/330.
2. Documentation updates. These were posted to LKML at
https://lkml.org/lkml/2013/5/20/348.
3. Miscellaneous fixes, including converting a few remaining printk()
calls to pr_*(). These were posted to LKML at
https://lkml.org/lkml/2013/5/20/324.
4. SRCU-related changes and fixes. These were posted to LKML at
https://lkml.org/lkml/2013/5/20/425.
5. Removal of TINY_PREEMPT_RCU in favor of TREE_PREEMPT_RCU for
single-CPU low-latency systems. These were posted to LKML at
https://lkml.org/lkml/2013/5/20/427."

Most of the stuff from kernel/sched.c was moved to kernel/sched/core.c long time
back and the comments/Documentation never got updated.
I figured it out when I was going through sched-domains.txt and so thought of
fixing it globally.
I haven't crossed check if the stuff that is referenced in sched/core.c by all
these files is still present and hasn't changed as that wasn't the motive behind
this patch.

Add AM43x ePOS EVM minimal DT source - this is a minimal one to get
it booting. Also include it in omap2plus dtbs and document bindings.
The hardware is under development.
