Adds support for the sensors integrated in to the Cintiq Companion
Hybrid. These sensors use by-and-large the same protocol as the
Cintiq 24HD touch.
NOTE: The ExpressKeys on the Cintiq Companion Hybrid are wired to
both the EMR controller and CPU GPIO pins. It may be necessary to
disable their functionality in this driver if building a custom
Android kernel for this device (lest two events be sent to userspace
for every button press).

Add a new driver to support synthetic keyboard. On the next generation
Hyper-V guest firmware, many legacy devices will not be emulated and this
driver will be required.
I would like to thank Vojtech Pavlik <vojtech@suse.cz> for helping me with the
details of the AT keyboard driver. I would also like to thank
Dan Carpenter <dan.carpenter@oracle.com> and

Pull networking fixes from David Miller:
1) There was a simplification in the ipv6 ndisc packet sending
attempted here, which avoided using memory accounting on the
per-netns ndisc socket for sending NDISC packets. It did fix some
important issues, but it causes regressions so it gets reverted here
too. Specifically, the problem with this change is that the IPV6
output path really depends upon there being a valid skb->sk
attached.
The reason we want to do this change in some form when we figure out
how to do it right, is that if a device goes down the ndisc_sk
socket send queue will fill up and block NDISC packets that we want
to send to other devices too. That's really bad behavior.
Hopefully Thomas can come up with a better version of this change.
2) Fix a severe TCP performance regression by reverting a change made
to dev_pick_tx() quite some time ago. From Eric Dumazet.
3) TIPC returns wrongly signed error codes, fix from Erik Hugne.
4) Fix OOPS when doing IPSEC over ipv4 tunnels due to orphaning the
skb->sk too early. Fix from Li Hongjun.
5) RAW ipv4 sockets can use the wrong routing key during lookup, from
Chris Clark.
6) Similar to #1 revert an older change that tried to use plain
alloc_skb() for SYN/ACK TCP packets, this broke the netfilter owner
mark which needs to see the skb->sk for such frames. From Phil
Oester.
7) BNX2x driver bug fixes from Ariel Elior and Yuval Mintz,
specifically in the handling of virtual functions.
8) IPSEC path error propagations to sockets is not done properly when
we have v4 in v6, and v6 in v4 type rules. Fix from Hannes Frederic
Sowa.
9) Fix missing channel context release in mac80211, from Johannes Berg.
10) Fix network namespace handing wrt. SCM_RIGHTS, from Andy
Lutomirski.
11) Fix usage of bogus NAPI weight in jme, netxen, and ps3_gelic

12) Hopefully a complete and correct fix for the genetlink dump locking
and module reference counting. From Pravin B Shelar.
13) sk_busy_loop() must do a cpu_relax(), from Eliezer Tamir.

Commit dc975382 "net: fec: add napi support to improve proformance"
converted the fec driver to the napi model. However, that commit
forgot to remove the call to skb_defer_rx_timestamp which is only
needed in non-napi drivers.
(The function napi_gro_receive eventually calls netif_receive_skb,
which in turn calls skb_defer_rx_timestamp.)
This patch should also be applied to the 3.9 and 3.10 kernels.

the series of patches for irqdomain core in 3.11 has broken sirf
irq which uses legacy mapping. all users fail in the new kernel
while setupping irq.
this patch moves to linear irqdomain and drop old legacy irqdomain
codes since we don't need it any more, and at the same time, it
also fixes the broken interrupts of sirfsoc in 3.11.
on the other hand, we actually only have 64 interrupt sources for
prima2 and atlas6, but there are 128 interrupt souces for marco
which uses GIC. in the legacy codes, sirf gpio also uses legacy
irqdomain, so to make gpio interrupt mapping not depend on the
prima2/atlas6/marco an use unified marco,we enlarge prima2/atlas6
interrupt number to 128. here we don't need this workaround any
more as sirf gpio also moved to linear mode before. so we move
SIRFSOC_NUM_IRQS back to 64 too.

"cat /sys/devices/system/memory/memory*/removable" crashed the system.
The problem is that show_mem_removable() is passing a
bad pfn to is_mem_section_removable(), which causes
if (!node_online(page_to_nid(page)))
to blow up. Why is it passing in a bad pfn?
The reason is that show_mem_removable() will loop sections_per_block
times. sections_per_block is 16, but mem->section_count is 8,
indicating holes in this memory block. Checking that the memory section
is present before checking to see if the memory section is removable
fixes the problem.

This patch adds another entry (HP hs2434 Mobile Broadband) to the list
of exceptional devices that require a zero length packet in order to
function properly. This list was added in commit 844e88f0. The hs2434
is manufactured by Sierra Wireless, who also produces the MC7710,
which the ZLP exception list was created for in the first place. So
hopefully it is just this one producer's devices that will need this
workaround.

If driver will fail to allocate all queues, it will shrink the number of
queues and move the storage queue to its correct place (i.e., the last
queue among the newly supported number).
When changing the pointers of the new location of the FCoE queue, we need
to pay special attention to the aggregations pointer - that memory is allocated
during probe and released upon driver removal. Current implementation has 2
pointers pointing to the same chunk of allocated memory, meaning upon removal
there will be two kfree() of the same chunk while the other won't be released.

handshake problem causing the console to fail to show up on a bunch of
machines until we reach userspace, which I deem annoying enough to
warrant going to stable, and a nasty gcc miscompile causing us to pass
virtual instead of physical addresses to the firmware under some
circumstances"
* 'merge' of git://git.kernel.org/pub/scm/linux/kernel/git/benh/powerpc:
powerpc/hvsi: Increase handshake timeout from 200ms to 400ms.
powerpc: Work around gcc miscompilation of __pa() on 64-bit
powerpc: Don't Oops when accessing /proc/powerpc/lparcfg without hypervisor

This solves a problem observed in kexec'ed kernel where 200ms timeout is
too short and bootconsole fails to initialize. Console did eventually
become workable but much later into the boot process.
Observed timeout was around 260ms, but I decided to make it a little bigger
for more reliability.
This has been tested on Power7 machine with Petitboot as a primary
bootloader and PowerNV firmware.

Commit 9a11899c5e69 (USB: OHCI: add missing PCI PM callbacks to
ohci-pci.c) added missing ohci_suspend and ohci_resume callback
pointers, but forgot that these callbacks are declared and defined
only when CONFIG_PM is enabled.
This patch adds a preprocessor conditional to avoid build errors when
PM is disabled.

In suspend-resume sequence, the OS could attempt to initialize the controller
before it is ready, check for POST state before going ahead.

This driver adds support for slidebars found on some Lenovo IdeaPad
laptops (the slidebars work with SlideNav/Desktop Navigator under
Windows).
Fixes: https://bugzilla.kernel.org/show_bug.cgi?id=16004
Registers 'IdeaPad Slidebar' input device and
/sys/devices/platform/ideapad_slidebar/slidebar_mode
for switching slidebar's modes.
Now works on:
IdeaPad Y550, Y550P.
May work on (testing and adding new models is needed):
Ideapad Y560, Y460, Y450, Y650,
and, probably, some others.

The IO command size is 128 bytes for these new controllers as opposed to 64
for the old 8001 controller.
The Adaptec out-of-tree driver did this correctly. After comparing the two
this turned out to be the crucial difference.
So don't hardcode the IO command size, instead use pm8001_ha->iomb_size as
that is the correct value for both old and new controllers.

OMAP4 is DT only, so read the keypad IRQ type from DT instead hard-coding
it in the driver.
