This patch programs the core and timing generator registers using the
timing data provided in drm_display_mode and not using hard-coded
configurations.
Additional PHY configs has been added. This allows us to support more
permissible resolutions and refresh rates.

With this patch, mixer driver find the correct resolution mode for
the range of resolutions, upto 1080 vertical lines. Resolution will
be categorized to NTSC SD, PAL SD or HD and the correct mode is
set to the mixer configuration register.

This patch adds the implementation of check_timing callback in the mixer
driver. Based on the mixer version, correct set of restrictions will be
exposed by the mixer driver. A resolution will be acceptable only if passes
the criteria set by mixer and hdmi IPs.

This patch adds the display mode check operation to exynos_mixer_ops
in drm-common-hdmi. In Exynos SoCs, mixer IP can put certain restrictions
on the proposed display modes. These restriction needs to be considered
during mode negotiation, which happens immediately after edid parsing.
Both, mixer check-mode and hdmi check-timing callbacks are called one after
another and ANDed result is returned back.

This patch fixes wrong pointer access issue to filp->f_op and
filp->private_data.
The exynos_drm_gem_mmap_ioctl() changes filp->f_op and
filp->private_data temporarily and restore them to use
original ones in exynos_drm_gem_mmap_buffer() but there
was no lock between the changing and the restoring so
wrong pointer access to filp->f_op and filp->private_data
was induced by vm close callback.
So this patch uses mutex lock properly to resolve this issue.

Pull networking update from David Miller:
1) Checkpoint/restarted TCP sockets now can properly propagate the TCP
timestamp offset. From Andrey Vagin.
2) VMWARE VM VSOCK layer, from Andy King.
3) Much improved support for virtual functions and SR-IOV in bnx2x,
from Ariel ELior.
4) All protocols on ipv4 and ipv6 are now network namespace aware, and
all the compatability checks for initial-namespace-only protocols is
removed. Thanks to Tom Parkin for helping deal with the last major
holdout, L2TP.
5) IPV6 support in netpoll and network namespace support in pktgen,
from Cong Wang.
6) Multiple Registration Protocol (MRP) and Multiple VLAN Registration
Protocol (MVRP) support, from David Ward.
7) Compute packet lengths more accurately in the packet scheduler, from
Eric Dumazet.
8) Use per-task page fragment allocator in skb_append_datato_frags(),
also from Eric Dumazet.
9) Add support for connection tracking labels in netfilter, from
Florian Westphal.
10) Fix default multicast group joining on ipv6, and add anti-spoofing
checks to 6to4 and 6rd. From Hannes Frederic Sowa.
11) Make ipv4/ipv6 fragmentation memory limits more reasonable in modern
times, rearrange inet frag datastructures for better cacheline
locality, and move more operations outside of locking. From Jesper
Dangaard Brouer.
12) Instead of strict master <--> slave relationships, allow arbitrary
scenerios with "upper device lists". From Jiri Pirko.
13) Improve rate limiting accuracy in TBF and act_police, also from Jiri
Pirko.
14) Add a BPF filter netfilter match target, from Willem de Bruijn.
15) Orphan and delete a bunch of pre-historic networking drivers from
Paul Gortmaker.
16) Add TSO support for GRE tunnels, from Pravin B SHelar. Although
this still needs some minor bug fixing before it's %100 correct in
all cases.
17) Handle unresolved IPSEC states like ARP, with a resolution packet
queue. From Steffen Klassert.
18) Remove TCP Appropriate Byte Count support (ABC), from Stephen
Hemminger. This was long overdue.
19) Support SO_REUSEPORT, from Tom Herbert.
20) Allow locking a socket BPF filter, so that it cannot change after a
process drops capabilities.
21) Add VLAN filtering to bridge, from Vlad Yasevich.
22) Bring ipv6 on-par with ipv4 and do not cache neighbour entries in
the ipv6 routes, from YOSHIFUJI Hideaki.

If an fsync occurs on a read-only array, we need to send a
completion for the IO and may not increment the active IO count.
Otherwise, we hit a bug trace and can't stop the MD array anymore.
By advice of Christoph Hellwig we return success upon a flush
request but we return -EROFS for other writes.
We detect flush requests by checking if the bio has zero sectors.
This patch is suitable to any -stable kernel to which it applies.

People are playing odd games with IRQF_DISABLED, remove it.
Its not reliable, since shared interrupt lines could disable it for you,
and its possible and allowed for archs to disable IRQs to limit IRQ nesting.
Therefore, simply mandate that _ALL_ IRQ handlers are run with IRQs disabled.
[ This _should_ not break anything, since we've mandated that IRQ handlers
_must_ be able to deal with this for a _long_ time ]
IRQ handlers should be fast, no if buts and any other exceptions. We also have
plenty instrumentation to find any offending IRQ latency sources.

This patch adds support for emulation of WRITE_SAME w/ UNMAP=0 within
fd_execute_write_same() backend code.
The emulation uses vfs_writev() to submit a locally populated buffer
from the received WRITE_SAME scatterlist block for duplication, and by
default enforces a limit of max_write_same_len=0x1000 (8192) sectors up
to the limit of 1024 iovec entries for the single call to vfs_writev().
It also sets max_write_same_len to the operational default at setup ->
fd_configure_device() time.
Tested with 512, 1k, 2k, and 4k block_sizes.

Pull battery updates from Anton Vorontsov:
"Four new drivers:
- goldfish_battery:
This is Android Emulator battery driver. Originally from Google,
but Intel folks reshaped it for mainline
- pm2301_charger:
A new driver for ST-Ericsson 2301 Power Management chip, uses
AB8500 battery management core
- qnap-poweroff:
The driver adds poweroff functionality for QNAP NAS boxes
- restart-poweroff:
A generic driver that implements 'power off by restarting'. The
actual poweroff functionality is implemented through a bootloader,
so Linux' task is just to restart the box. The driver is useful on
Buffalo Linkstation LS-XHL and LS-CHLv2 boards. Andrew Lunn worked
on submitting the driver (as well as qnap-poweroff above).
Additionally:
- A lot of fixes for ab8500 drivers. This is a part of efforts of
syncing internal ST-Ericsson development tree with the mainline.
Lee Jones @ Linaro worked on compilation and reshaping these
series.
- New health properties for the power supplies: "Watchdog timer
expire" and "Safety timer expire"
- As usual, a bunch of fixes/cleanups here and there"

power: Add battery driver for goldfish emulator
u8500-charger: Delay for USB enumeration
ab8500-bm: Remove individual [charger|btemp|fg|chargalg] pdata structures

...
Fix up fairly straightforward conflicts in the ab8500 driver. But since
it seems to be ARM-specific, I can't even compile-test the result..

Pull pinctrl changes from Linus Walleij:
"These are the main pinctrl changes for the v3.9 merge window. The
most interesting change by far is how the device core grabs pinctrl
default handles avoiding the need to stick boilerplate into driver
consumers.
- Grabbing of default pinctrl handles from the device core. These
are the hunks hitting drivers/base. All is ACKed by Greg, after a
long discussion about different alternatives.
- Some stuff also touches the MFD and ARM SoC trees, this has been
coordinated and ACKed.
- New drivers for:
- The Tegra 114 sub-SoC
- Allwinner sunxi
- New ABx500 driver and sub-SoC drivers for AB8500, AB8505, AB9540
and AB8540.
- Make it possible for hogged pins to enter a sleep mode, and make it
possible for drivers to control that mode.
- Various clean-up, extensions and device tree support to various pin
controllers."

Pull regmap updates from Mark Brown:
"Several nice new features and performance improvements here,
especially the first:
- Support for using the cache infrastructure without the physical
I/O, allowing devices which don't fit the physical model regmap has
to take advantage of the cache infrastructure, contributed by
Andrey Smirnov.
- Several small improvements to the support for wake capable IRQs.
- Support for asynchronous I/O, allowing us to come much closer to
saturating fast buses like SPI.
- Support for simple array caches, giving higher performance for use
with MMIO devices.
- Restoration of the use of bulk reads for handling interrupts,
giving a performance improvement.
- Support for 24 bit register addresses.
- More performance improvements for debugfs."
