Attempt to use the new DLM operations. If it is not supported, use the
traditional ocfs2_controld.
To exchange ocfs2 versioning, we use the LVB of the version dlm lock.
It first attempts to take the lock in EX mode (non-blocking). If
successful (which means it is the first mount), it writes the version
number and downconverts to PR lock. If it is unsuccessful, it reads the
version from the lock.
If this becomes the standard (with o2cb as well), it could simplify
userspace tools to check if the filesystem is mounted on other nodes.
Dan: Since ocfs2_protocol_version are two u8 values, the additional
checks with LONG* don't make sense.

This is done to differentiate between using and not using controld and
use the connection information accordingly.
We need to be backward compatible. So, we use a new enum
ocfs2_connection_type to identify when controld is used and when it is
not.

We perform this because the DLM recovery callbacks will require the
ocfs2_live_connection structure to record the node information when
dlm_new_lockspace() is updated (in the last patch of the series).
Before calling dlm_new_lockspace(), we need the structure ready for the
.recover_done() callback, which would set oc_this_node. This is the
reason we allocate ocfs2_live_connection beforehand in user_connect().
[AKPM] rc initialization is not required because it assigned in case of
errors. It will be cleared by compiler anyways.

These are the callbacks called by the fs/dlm code in case the membership
changes. If there is a failure while/during calling any of these, the
DLM creates a new membership and relays to the rest of the nodes.
- recover_prep() is called when DLM understands a node is down.
- recover_slot() is called once all nodes have acknowledged
recover_prep and recovery can begin.
- recover_done() is called once the recovery is complete. It returns
the new membership.

This is an effort of removing ocfs2_controld.pcmk and getting ocfs2 DLM
handling up to the times with respect to DLM (>=4.0.1) and corosync
(2.3.x). AFAIK, cman also is being phased out for a unified corosync
cluster stack.
fs/dlm performs all the functions with respect to fencing and node
management and provides the API's to do so for ocfs2. For all future
references, DLM stands for fs/dlm code.
The advantages are:
+ No need to run an additional userspace daemon (ocfs2_controld)
+ No controld device handling and controld protocol
+ Shifting responsibilities of node management to DLM layer
For backward compatibility, we are keeping the controld handling code.
Once enough time has passed we can remove a significant portion of the
code. This was tested by using the kernel with changes on older
unmodified tools. The kernel used ocfs2_controld as expected, and
displayed the appropriate warning message.
This feature requires modification in the userspace ocfs2-tools. The
changes can be found at: https://github.com/goldwynr/ocfs2-tools branch:
nocontrold Currently, not many checks are present in the userspace code,
but that would change soon.
This patch (of 6):
Add clustername to cluster connection.

dma_pte_free_level() has an off-by-one error when checking whether a pte
is completely covered by a range. Take for example the case of
attempting to free pfn 0x0 - 0x1ff, ie. 512 entries covering the first
2M superpage.
The level_size() is 0x200 and we test:
static void dma_pte_free_level(...
...
if (!(0 > 0 || 0x1ff < 0 + 0x200)) {
...
}
Clearly the 2nd test is true, which means we fail to take the branch to
clear and free the pagetable entry. As a result, we're leaking
pagetables and failing to install new pages over the range.
This was found with a PCI device assigned to a QEMU guest using vfio-pci
without a VGA device present. The first 1M of guest address space is
mapped with various combinations of 4K pages, but eventually the range
is entirely freed and replaced with a 2M contiguous mapping.
intel-iommu errors out with something like:
ERROR: DMA PTE for vPFN 0x0 already set (to 5c2b8003 not 849c00083)
In this case 5c2b8003 is the pointer to the previous leaf page that was
neither freed nor cleared and 849c00083 is the superpage entry that
we're trying to replace it with.

Currently fsnotify framework creates one event structure for each
notification event and links this event into all interested notification
groups. This is done so that we save memory when several notification
groups are interested in the event. However the need for event
structure shared between inotify & fanotify bloats the event structure
so the result is often higher memory consumption.
Another problem is that fsnotify framework keeps path references with
outstanding events so that fanotify can return open file descriptors
with its events. This has the undesirable effect that filesystem cannot
be unmounted while there are outstanding events - a regression for
inotify compared to a situation before it was converted to fsnotify
framework. For fanotify this problem is hard to avoid and users of
fanotify should kind of expect this behavior when they ask for file
descriptors from notified files.
This patch changes fsnotify and its users to create separate event
structure for each group. This allows for much simpler code (~400 lines
removed by this patch) and also smaller event structures. For example
on 64-bit system original struct fsnotify_event consumes 120 bytes, plus
additional space for file name, additional 24 bytes for second and each
subsequent group linking the event, and additional 32 bytes for each
inotify group for private data. After the conversion inotify event
consumes 48 bytes plus space for file name which is considerably less
memory unless file names are long and there are several groups
interested in the events (both of which are uncommon). Fanotify event
fits in 56 bytes after the conversion (fanotify doesn't care about file
names so its events don't have to have it allocated). A win unless
there are four or more fanotify groups interested in the event.
The conversion also solves the problem with unmount when only inotify is
used as we don't have to grab path references for inotify events.

Record actively mapped pages and provide an api for asserting a given
page is dma inactive before execution proceeds. Placing
debug_dma_assert_idle() in cow_user_page() flagged the violation of the
dma-api in the NET_DMA implementation (see commit 7787380336 "net_dma:
mark broken").
The implementation includes the capability to count, in a limited way,
repeat mappings of the same page that occur without an intervening
unmap. This 'overlap' counter is limited to the few bits of tag space
in a radix tree. This mechanism is added to mitigate false negative
cases where, for example, a page is dma mapped twice and
debug_dma_assert_idle() is called after the page is un-mapped once.

It was holiday season, so no wonder that there are little changes in
framework level, although diffstat shows quite many changes spreaded
over sound/* directories. Most of changes are cleanups, code
refactoring and fixes.
Some highlights:
- Removal of OSS sleep_on usages by Arnd
- Simplified memalloc helper codes, drop obsoleted features;
now it's built into PCM driver instead of an individual module
- Warn if PCM buffer preallocation fails, which will show page
allocation issues more clearly
- Compress offload API updates for sample rates by Vinod
- PCM glitch workaround on ctxfi emu20k1 by Sarah
- Drop cs46xx DSP blobs, using firmware loader now
- USB-audio quitks for Plantronics Gamecom 780, Creative VF0420,
and Focusrite Saffire 6
HD-audio specifics:
- Standardize Kconfigs of HD-audio codec drivers;
now "make localmodconfig" recognizes configs properly (finally!)
- Parallel PM implementation by Mengdong
- BayleyBay/ValleyView2 board fixups
- Broadwell audio support
- Runtime PM improvement (PantherPoint, etc)
- Quirks: Dell subwooer, Gigabyte mobo jack detection oddity,
Dell AiO click noise fixes, Dell headset mic fixes, etc
- Automatic bind with HDMI codec parser without generic parser
- More AD codec fixes (since 3.12 regression) including the automatic
stereo mix support
- Common Thinkpad ACPI helper for Realtek and Conexant codecs
ASoC specifics:
- Update to the generic DMA code to support deferred probe and managed
resources
- New drivers for BCM2835 (used in Raspberry Pi), Tegra with MAX98090
and Analog Devices AXI I2S and S/PDIF controller IPs
- Device tree support for the simple card, max98090 and cs42l52
- Conversion of the Samsung drivers to native dmaengine, making them
multiplatform compatible and hopefully helping keep them more modern
and up to date.
- More regmap conversions, including a very welcome one for twl6040
from Peter Ujfalusi
- A big overhaul of the DaVinci drivers also from Peter Ujfalusi
- Lots of DMA updates from Lars-Peter
- Improvements to the constraints handling code from Lars-Peter
- A very helpful conversion of the TWL4030 driver to regmap from Peter
- A new driver for the Freescale ESAI controller from Nicolin Chen
- Conversion of some of the drivers to use params_width()

framework level, although diffstat shows quite many changes spreaded
over sound/* directories. Most of changes are cleanups, code
refactoring and fixes.
Some highlights:
- Removal of OSS sleep_on usages by Arnd
- Simplified memalloc helper codes, drop obsoleted features; now it's
built into PCM driver instead of an individual module
- Warn if PCM buffer preallocation fails, which will show page
allocation issues more clearly
- Compress offload API updates for sample rates by Vinod
- PCM glitch workaround on ctxfi emu20k1 by Sarah
- Drop cs46xx DSP blobs, using firmware loader now
- USB-audio quitks for Plantronics Gamecom 780, Creative VF0420, and
Focusrite Saffire 6
HD-audio specifics:
- Standardize Kconfigs of HD-audio codec drivers; now "make
localmodconfig" recognizes configs properly (finally!)
- Parallel PM implementation by Mengdong
- BayleyBay/ValleyView2 board fixups
- Broadwell audio support
- Runtime PM improvement (PantherPoint, etc)
- Quirks: Dell subwooer, Gigabyte mobo jack detection oddity, Dell
AiO click noise fixes, Dell headset mic fixes, etc
- Automatic bind with HDMI codec parser without generic parser
- More AD codec fixes (since 3.12 regression) including the automatic
stereo mix support
- Common Thinkpad ACPI helper for Realtek and Conexant codecs
ASoC specifics:
- Update to the generic DMA code to support deferred probe and
managed resources
- New drivers for BCM2835 (used in Raspberry Pi), Tegra with MAX98090
and Analog Devices AXI I2S and S/PDIF controller IPs
- Device tree support for the simple card, max98090 and cs42l52
- Conversion of the Samsung drivers to native dmaengine, making them
multiplatform compatible and hopefully helping keep them more
modern and up to date.
- More regmap conversions, including a very welcome one for twl6040
from Peter Ujfalusi
- A big overhaul of the DaVinci drivers also from Peter Ujfalusi
- Lots of DMA updates from Lars-Peter
- Improvements to the constraints handling code from Lars-Peter
- A very helpful conversion of the TWL4030 driver to regmap from Peter
- A new driver for the Freescale ESAI controller from Nicolin Chen
- Conversion of some of the drivers to use params_width()
- Extensions to DPCM for use with compressed audio from Liam"

A big set this merge window, as we have much going on in
this subsystem. Major changes this time:
- Some core improvements and cleanups to the new GPIO
descriptor API. This seems to be working now so we can
start the exodus to this API, moving gradually away from
the global GPIO numberspace.
- Incremental improvements to the ACPI GPIO core, and move
the few GPIO ACPI clients we have to the GPIO descriptor
API right *now* before we go any further. We actually
managed to contain this *before* we started to litter
the kernel with yet another hackish global numberspace for
the ACPI GPIOs, which is a big win.
- The RFkill GPIO driver and all platforms using it have
been migrated to use the GPIO descriptors rather than
fixed number assignments. Tegra machine has been migrated
as part of this.
- New drivers for MOXA ART, Xtensa GPIO32 and SMSC SCH311x.
Those should be really good examples of how I expect a
nice GPIO driver to look these days.
- Do away with custom GPIO implementations on a major
part of the ARM machines: ks8695, lpc32xx, mv78xx0.
Make a first step towards the same in the horribly
convoluted Samsung S3C include forest. We expect to
continue to clean this up as we move forward.
- Flag GPIO lines used for IRQ on adnp, bcm-kona, em,
intel-mid and lynxpoint.
This makes the GPIOlib core aware that a certain GPIO line
is used for IRQs and can then enforce some semantics such
as disallowing a GPIO line marked as in use for IRQ to be
switched to output mode.
- Drop all use of irq_set_chip_and_handler_name().
The name provided in these cases were just unhelpful
tags like "mux" or "demux".
- Extend the MCP23s08 driver to handle interrupts.
- Minor incremental improvements for rcar, lynxpoint, em
74x164 and msm drivers.
- Some non-urgent bug fixes here and there, duplicate
#includes and that usual kind of cleanups.

mfd_add_device() assigns .of_node in the device objects it creates only
if the mfd_cell for the device has the .of_compatible field set and the
DT node for the top-level MFD device contains a child whose compatible
property matches the cell's .of_compatible field.
This leaves .of_node unset in many cases. When this happens, entries in
the DT /aliases property which refer to the top-level MFD DT node will
never match the MFD child devices, hence causing the requested alias not
to be honored.
Solve this by setting each MFD child device's .of_node equal to the top-
level MFD device's .of_node field in the cases where it would otherwise
remain unset.
The first use-case for this will be aliases for the TPS6586x's RTC
device.

The EC has specific timing it requires. Add support for an optional delay
after raising CS to fix timing issues. This is configurable based on
a DT property "google,cros-ec-spi-msg-delay".
If this property isn't set, then no delay will be added. However, if set
