Pull i2c updates from Wolfram Sang:
- new drivers: Kontron PLD, Wondermedia VT
- mv64xxx driver gained sun4i support and a bigger cleanup
- duplicate driver 'intel-mid' removed
- added generic device tree binding for sda holding time (and
designware driver already uses it)
- we tried to allow driver probing with only device tree and no i2c
ids, but I had to revert it because of side effects. Needs some
rethinking.
- driver bugfixes, cleanups...

Merge Kconfig menu diet patches from Dave Hansen:
"I think the "Kernel Hacking" menu has gotten a bit out of hand. It is
over 120 lines long on my system with everything enabled and options
are scattered around it haphazardly.
http://sr71.net/~dave/linux/kconfig-horror.png
Let's try to introduce some sanity. This set takes that 120 lines
down to 55 and makes it vastly easier to find some things. It's a
start.
This set stands on its own, but there is plenty of room for follow-up
patches. The arch-specific debug options still end up getting stuck
in the top-level "kernel hacking" menu. OPTIMIZE_INLINING, for
instance, could obviously go in to the "compiler options" menu, but
the fact that it is defined in arch/ in a separate Kconfig file keeps
it on its own for the moment.
The Signed-off-by's in here look funky. I changed employers while
working on this set, so I have signoffs from both email addresses"

tweak compilation in some way, or perform extra compile-time

These runtime tests are great, except that there are a lot of them,
and they are very rarely needed. Give them their own menu so that
only the folks who need them will have to go looking for them.
Note that there are some other runtime tests that are not in here,
like for RCU or locking. This menu should only be used for tests
that do not have a more appropriate home.

There are a *LOT* of memory debugging options. They are just scattered
all over the "Kernel Hacking" menu. Sure, "memory debugging" is a very
vague term and it's going to be hard to make absolute rules about what
goes in here, but this has to be better than what we had before.
This does, however, leave out the architecture-specific memory
debugging options (like x86's DEBUG_SET_MODULE_RONX). There would need
to be some substantial changes to move those in here. Kconfig can not
easily mix arch-specific and generic options together: it really
requires a file per-architecture, and I think having an
arch/foo/Kconfig.debug-memory might be taking things a bit too far

Pull powerpc updates from Ben Herrenschmidt:
"This is the powerpc changes for the 3.11 merge window. In addition to
the usual bug fixes and small updates, the main highlights are:
- Support for transparent huge pages by Aneesh Kumar for 64-bit
server processors. This allows the use of 16M pages as transparent
huge pages on kernels compiled with a 64K base page size.
- Base VFIO support for KVM on power by Alexey Kardashevskiy
- Wiring up of our nvram to the pstore infrastructure, including
putting compressed oopses in there by Aruna Balakrishnaiah
- Move, rework and improve our "EEH" (basically PCI error handling
and recovery) infrastructure. It is no longer specific to pseries
but is now usable by the new "powernv" platform as well (no
hypervisor) by Gavin Shan.
- I fixed some bugs in our math-emu instruction decoding and made it
usable to emulate some optional FP instructions on processors with
hard FP that lack them (such as fsqrt on Freescale embedded
processors).
- Support for Power8 "Event Based Branch" facility by Michael
Ellerman. This facility allows what is basically "userspace
interrupts" for performance monitor events.
- A bunch of Transactional Memory vs. Signals bug fixes and HW
breakpoint/watchpoint fixes by Michael Neuling.
And more ... I appologize in advance if I've failed to highlight
something that somebody deemed worth it."

Intuos4 WL is separately reporting power supply and battery
charging status - now hid-wacom is using that information.
Previously hid-wacom was wrongly treating "battery charging" bit
as "power supply connected". Now it should report battery charging,
battery discharging, battery full and power supply status.
Intuos4 WL sends reports when is in use (obvious) and when unplugging
power supply. If means that if the device is being charged, but it's not
being used it will never report "battery full". The same problem happens
after the device has been connected, but it's not in use - the
battery/ac status will be incorrect. Currently there is no mechanism to
ask the device to send a report containing battery/ac status.

The recent comment:
commit 7e83ccbecd
md/raid10: Allow skipping recovery when clean arrays are assembled
Causes raid10 to skip a recovery in certain cases where it is safe to
do so. Unfortunately it also causes a reshape to be skipped which is
never safe. The result is that an attempt to reshape a RAID10 will
appear to complete instantly, but no data will have been moves so the
array will now contain garbage.
(If nothing is written, you can recovery by simple performing the
reverse reshape which will also complete instantly).
Bug was introduced in 3.10, so this is suitable for 3.10-stable.

There is a bug in 'check_reshape' for raid5.c To checks
that the new minimum number of devices is large enough (which is
good), but it does so also after the reshape has started (bad).
This is bad because
- the calculation is now wrong as mddev->raid_disks has changed
already, and
- it is pointless because it is now too late to stop.
So only perform that test when reshape has not been committed to.
