"These changes provide support for PCIe root complex and USB host mode
for tilegx's on-chip I/Os.
In addition, this pull provides the required underpinning for the
on-chip networking support that was pulled into 3.5. The changes have
all been through LKML (with several rounds for PCIe RC) and on
linux-next."

Pull powerpc updates from Benjamin Herrenschmidt:
"Notable highlights:
- iommu improvements from Anton removing the per-iommu global lock in
favor of dividing the DMA space into pools, each with its own lock,
and hashed on the CPU number. Along with making the locking more
fine grained, this gives significant improvements in multiqueue
networking scalability.
- Still from Anton, we know provide a vdso based variant of getcpu
which makes sched_getcpu with the appropriate glibc patch something
like 18 times faster.
- More anton goodness (he's been busy !) in other areas such as a
faster __clear_user and copy_page on P7, various perf fixes to
improve sampling quality, etc...
- One more step toward removing legacy i2c interfaces by using new
device-tree based probing of platform devices for the AOA audio
drivers
- A nice series of patches from Michael Neuling that helps avoiding
confusion between register numbers and litterals in assembly code,
trying to enforce the use of "%rN" register names in gas rather
than plain numbers.
- A pile of FSL updates
- The usual bunch of small fixes, cleanups etc...
You may spot a change to drivers/char/mem. The patch got no comment
or ack from outside, it's a trivial patch to allow the architecture to
skip creating /dev/port, which we use to disable it on ppc64 that
don't have a legacy brige. On those, IO ports 0...64K are not mapped
in kernel space at all, so accesses to /dev/port cause oopses (and
yes, distros -still- ship userspace that bangs hard coded ports such
as kbdrate)."

This adds support for three new SoC types:
* The mvebu platform includes Marvell's Armada XP and Armada 370 chips,
made by the mvebu business unit inside of Marvell. Since the same
group also made the older but similar platforms we call "orion5x",
"kirkwood", "mv78xx0" and "dove", we plan to move all of them into
the mach-mvebu directory in the future.
* socfpga is Altera's platform based on Cortex-A9 cores and a lot of
FPGA space. This is similar to the Xilinx zynq platform we already
support. The code is particularly clean, which is helped by the fact
that the hardware doesn't do much besides the parts that are
expected to get added in the FPGA.
* The OMAP subarchitecture gains support for the latest generation,
the OMAP5 based on the new Cortex-A15 core. Support is rather
rudimentary for now, but will be extended in the future.

This branch contains two kinds of updates: Some platforms in the process
of getting converted to device tree based booting, and the platform
specific patches necessary for that are included here. Other platforms
are already converted, so we just need to update the actual device
tree source files and the binding documents to add support for new board
and new drivers.
In the future we will probably separate those into two branches, and
in the long run, the plan is to move the device tree source files out
of the kernel repository, but that has to wait until we have completed
a much larger portion of the binding documents.

Pull the big VFS changes from Al Viro:
"This one is *big* and changes quite a few things around VFS. What's in there:
- the first of two really major architecture changes - death to open
intents.
The former is finally there; it was very long in making, but with
Miklos getting through really hard and messy final push in
fs/namei.c, we finally have it. Unlike his variant, this one
doesn't introduce struct opendata; what we have instead is
->atomic_open() taking preallocated struct file * and passing
everything via its fields.
Instead of returning struct file *, it returns -E... on error, 0
on success and 1 in "deal with it yourself" case (e.g. symlink
found on server, etc.).
See comments before fs/namei.c:atomic_open(). That made a lot of
goodies finally possible and quite a few are in that pile:
->lookup(), ->d_revalidate() and ->create() do not get struct
nameidata * anymore; ->lookup() and ->d_revalidate() get lookup
flags instead, ->create() gets "do we want it exclusive" flag.
With the introduction of new helper (kern_path_locked()) we are rid
of all struct nameidata instances outside of fs/namei.c; it's still
visible in namei.h, but not for long. Come the next cycle,
declaration will move either to fs/internal.h or to fs/namei.c
itself. [me, miklos, hch]
- The second major change: behaviour of final fput(). Now we have
__fput() done without any locks held by caller *and* not from deep
in call stack.
That obviously lifts a lot of constraints on the locking in there.
Moreover, it's legal now to call fput() from atomic contexts (which
has immediately simplified life for aio.c). We also don't need
anti-recursion logics in __scm_destroy() anymore.
There is a price, though - the damn thing has become partially
asynchronous. For fput() from normal process we are guaranteed
that pending __fput() will be done before the caller returns to
userland, exits or gets stopped for ptrace.
For kernel threads and atomic contexts it's done via
schedule_work(), so theoretically we might need a way to make sure
it's finished; so far only one such place had been found, but there
might be more.
There's flush_delayed_fput() (do all pending __fput()) and there's
__fput_sync() (fput() analog doing __fput() immediately). I hope
we won't need them often; see warnings in fs/file_table.c for
details. [me, based on task_work series from Oleg merged last
cycle]
- sync series from Jan
- large part of "death to sync_supers()" work from Artem; the only
bits missing here are exofs and ext4 ones. As far as I understand,
those are going via the exofs and ext4 trees resp.; once they are
in, we can put ->write_super() to the rest, along with the thread
calling it.
- preparatory bits from unionmount series (from dhowells).
- assorted cleanups and fixes all over the place, as usual.
This is not the last pile for this cycle; there's at least jlayton's
ESTALE work and fsfreeze series (the latter - in dire need of fixes,
so I'm not sure it'll make the cut this cycle). I'll probably throw
symlink/hardlink restrictions stuff from Kees into the next pile, too.
Plus there's a lot of misc patches I hadn't thrown into that one -
it's large enough as it is..."

Lots and lots of fixes from Axel and some others here, plus some framework
enhancements which continue the theme of factoring code out of the drivers
and into the core.
- Initial framework support for GPIO controlled enable signals, saving a
bunch of code in drivers.
- Move fixed regulator enable time and voltage mapping table
specifications to data.
- Used some of the recent framework enhancements to make voltage change
notifications more useful, passing the voltage in as an argument to the
notification.
- Fixed the pattern used for finding individual regulators on a device
to not rely on the node name, supporting the use of multiple PMICs of
the same type in the system.
- New drivers for Maxim MAX77686, TI LP872x and LP8788, Samsung S2MPS11,
and Wolfson Arizona microphone supplies and LDOs.

Merge tag 'regmap-3.6' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regmap
Pull regmap updates from Mark Brown:
"A few fixes plus a few features, the most generally useful thing being
the register paging support which can be used by quite a few devices:
- Support for wake IRQs in regmap-irq
- Support for register paging
- Support for explicitly specified endianness, mostly for MMIO."
* tag 'regmap-3.6' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regmap:

regmap: Add hook for printk logging for debugging during early init
regmap: Fix work_buf switching for page update during virtual range access.
regmap: Add support for register indirect addressing.
regmap: Move lock out from internal function _regmap_update_bits().
regmap: mmio: Staticize regmap_mmio_gen_context()
regmap: Remove warning on stubbed dev_get_regmap()
regmap: Implement support for wake IRQs
regmap: Don't try to map non-existant IRQs

For ext3/4 htree directories, using the vfs llseek function with
SEEK_END goes to i_size like for any other file, but in reality
we want the maximum possible hash value. Recent changes
in ext4 have cut & pasted generic_file_llseek() back into fs/ext4/dir.c,
but replicating this core code seems like a bad idea, especially
since the copy has already diverged from the vfs.
This patch updates generic_file_llseek_size to accept
both a custom maximum offset, and a custom EOF position. With this
in place, ext4_dir_llseek can pass in the appropriate maximum hash
position for both maxsize and eof, and get what it wants.
As far as I know, this does not fix any bugs - nfs in the kernel
doesn't use SEEK_END, and I don't know of any user who does. But
some ext4 folks seem keen on doing the right thing here, and I can't
really argue.
(Patch also fixes up some comments slightly)

... and schedule_work() for interrupt/kernel_thread callers
(and yes, now it *is* OK to call from interrupt).
We are guaranteed that __fput() will be done before we return
to userland (or exit). Note that for fput() from a kernel
thread we get an async behaviour; it's almost always OK, but
sometimes you might need to have __fput() completed before
you do anything else. There are two mechanisms for that -
a general barrier (flush_delayed_fput()) and explicit
__fput_sync(). Both should be used with care (as was the
case for fput() from kernel threads all along). See comments
in fs/file_table.c for details.

Host has different current capabilities at different voltages, we need
to record these settings seperately. The defined voltages are 1.8/3.0/3.3.
For other voltages, we do not touch current limit setting.
Before we set the current limit for the sd card, find out the host's
operating voltage first and then find out the current capabilities of
the host at that voltage to set the current limit.

Add a new flag of SDHCI_USING_RETUNING_TIMER to represent if the host
is using a retuning timer for the card inserted.
This flag is set when the host does tuning the first time for the card
and the host's retuning mode is 1. This flag is used afterwards whenever
needs to decide if the host is currently using a retuning timer.
This flag is cleared when the card is removed in sdhci_reinit.
The set/clear of the flag and the start/stop of the retuning timer is
associated with the card's init/remove time, so there is no need to
touch it when the host is to be removed as at that time the card should
have already been removed.

Currently only the capability_0 register can be set if
SDHCI_QUIRK_MISSING_CAPS is defined. This is a problem when
the capability_1 register also needs changing. Use the quirk
SDHCI_QUIRK_MISSING_CAPS to allow both registers to be set.
Redefining caps[1] is useful when the board design does not
support 1.8v vccq so UHS modes are not available. The code that
calls sdhci_add_host can then detect this condition and adjust
the caps so the UHS mode will not be attempted on UHS cards.

Pull RCU changes from Ingo Molnar:
"Quoting from Paul, the major features of this series are:
1. Preventing latency spikes of more than 200 microseconds for
kernels built with NR_CPUS=4096, which is reportedly becoming the
default for some distros. This is a first step, as it does not
help with systems that actually -have- 4096 CPUs (work on this case
is in progress, but is not yet ready for mainline).
This category also includes improving concurrency of rcu_barrier(),
placed here due to conflicts. Posted to LKML at:
https://lkml.org/lkml/2012/6/22/381
Note that patches 18-22 of that series have been defered to 3.7, as
they have not yet proven themselves to be mainline-ready (and yes,
these are the ones intended to get rid of RCU's latency spikes for
systems that actually have 4096 CPUs).
2. Updates to documentation and rcutorture fixes, the latter category
including improvements to rcu_barrier() testing. Posted to LKML at
http://lkml.indiana.edu/hypermail/linux/kernel/1206.1/04094.html.

Merge emailed kgdb dmesg fixups patches from Anton Vorontsov:
"The dmesg command appears to be broken after the printk rework. The
old logic in the kdb code makes no sense in terms of current
printk/logging storage format, and KDB simply hangs forever upon
entering 'dmesg' command.
The first patch revives the command by switching to kmsg_dumper
iterator. As a side-effect, the code is now much more simpler.
A few changes were needed in the printk.c: we needed unlocked variant
of the kmsg_dumper iterator, but these can surely wait for 3.6.
It's probably too late even for the first patch to go to 3.5, but I'll
try to convince otherwise. :-) Here we go:
- The current code is broken for sure, and has no hope to work at
all. It is a regression
- The new code works for me, and probably works for everyone else;
- If it compiles (and I urge everyone to compile-test it on your
setup), it hardly can make things worse."

kdb: Switch to nolock variants of kmsg_dump functions
printk: Implement some unlocked kmsg_dump functions
printk: Remove kdb_syslog_data
kdb: Revive dmesg command
If used from KDB, the locked variants are prone to deadlocks (suppose we
got to the debugger w/ the logbuf lock held).
So, we have to implement a few routines that grab no logbuf lock.
Yet we don't need these functions in modules, so we don't export them.
