Persuant to Liran's comments on node_type on linux-rdma
mailing list:
In an effort to reform the RDMA core and ULPs to minimize use of
node_type in struct ib_device, an additional bit is added to
struct ib_device for is_switch (IB switch). This is needed
to be initialized by any IB switch device driver. This is a
NEW requirement on such device drivers which are all
"out of tree".
In addition, an ib_switch helper was added to ib_verbs.h
based on the is_switch device bit rather than node_type
(although those should be consistent).
The RDMA core (MAD, SMI, agent, sa_query, multicast, sysfs)
as well as (IPoIB and SRP) ULPs are updated where
appropriate to use this new helper. In some cases,
the helper is now used under the covers of using
rdma_[start end]_port rather than the open coding
previously used.

This reverts commit 19ee835cdb0b5a8eb11a68f25a51b8039d564488.
It breaks existing old userspace which doesn't handle UNKNOWN
swizzling correct. Yes UNKNOWN was a thing back in 2009 and probably
still is on some other platforms, but it still pretty clearly broke
the testers machine. If we want this we need to extend the ioctl with
new paramters that only new userspace looks at.

Previously only core DRM ioctls under the DRM_COMMAND_BASE were being
forwarded, but the drm.h header suggests (and reality confirms) ones
after (and including) DRM_COMMAND_END should be forwarded as well.
We need this to correctly forward the compat ioctl for the botched-up

When a cdev is contained in a dynamic structure the cdev parent kobj
should be set to the kobj that controls the lifetime of the enclosing
structure. In TPM's case this is the embedded struct device.
Also, cdev_init 0's the whole structure, so all sets must be after,
not before. This fixes module ref counting and cdev.

- fix missing REGMAP_I2C dependency
- rework the error handling for raw readings to fix an failure to power

* mmc35240 - reported samplign frequencies were wrong.
* ltr501 fixes
- fix a case of returning the return value of a regmap_read instead of
the value read.
- fix missing regmap dependency
* sx9500 - fix missing default values for ret in a couple of places to handle
the case of no enabled channels.
* tmp006 - check that writes to info_mask elements are actually to writable

Jonathan writes:
First set of IIO fixes for the 4.2 cycle.
* Fix a regression in hid sensors suspend time as a result of adding runtime
pm. The normal flow of waking up devices in order to go into suspend
(given the devices are normally suspended when not reading) to a regression
in suspend time on some laptops (reports of an additional 8 seconds).
Fix this by checking to see if a user action resulting in the wake up, and
make it a null operation if it didn't. Note that for hid sensors, there is
nothing useful to be done when moving into a full suspend from a runtime
suspend so they might as well be left alone.
* rochip_saradc: fix some missing MODULE_* data including the licence so that
the driver does not taint the kernel incorrectly and can build as a module.
* twl4030 - mark irq as oneshot as it always should have been.
* inv-mpu - write formats for attributes not specified, leading to miss
interpretation of the gyro scale channel when written.
* Proximity ABI clarification. This had snuck through as a mess. Some
drivers thought proximity went in one direction, some the other. We went
with the most common option, documented it and fixed up the drivers going
the other way. Fix for sx9500 included in this set.
* ad624r - fix a wrong shift in the output data.
* at91_adc - remove a false limit on the value of the STARTUP register
applied by too small a type for the device tree parameter.
* cm3323 - clear the bits when setting the integration time (otherwise
we can only ever set more bits in the relevant field).
* bmc150-accel - multiple triggers are registered, but on error were not being
unwound in the opposite order leading to removal of triggers that had not
yet successfully been registered (count down instead of up when unwinding).
* tcs3414 - ensure right part of val / val2 pair read so that the integration
time is not always 0.
* cc10001_adc - bug in kconfig dependency. Use of OR when AND was intended.

Indeed embarrassing. I've missed that we still have 1 caller left that's
using the transitional helpers, and those don't fill out
plane_state->state backpointers to the global atomic update since there is
no global atomic update for transitional helpers. Below diff should fix
this - we need to preferentially check crts_state->active and if that's
not set intel_crtc->active should yield the right result for the one
remaining caller (it's in the crtc_disable paths).

We have 3 types of DMA mappings for GEM objects:
1. physically contiguous for stolen and for objects needing contiguous
memory
2. DMA-buf mappings imported via a DMA-buf attach operation
3. SG DMA mappings for shmem backed and userptr objects
For 1. and 2. the lifetime of the DMA mapping matches the lifetime of the
corresponding backing pages and so in practice we create/release the
mapping in the object's get_pages/put_pages callback.
For 3. the lifetime of the mapping matches that of any existing GPU binding
of the object, so we'll create the mapping when the object is bound to
the first vma and release the mapping when the object is unbound from its
last vma.
Since the object can be bound to multiple vmas, we can end up creating a
new DMA mapping in the 3. case even if the object already had one. This
is not allowed by the DMA API and can lead to leaked mapping data and
IOMMU memory space starvation in certain cases. For example HW IOMMU
drivers (intel_iommu) allocate a new range from their memory space
whenever a mapping is created, silently overriding a pre-existing
mapping.
Fix this by moving the creation/removal of DMA mappings to the object's
get_pages/put_pages callbacks. These callbacks already check for and do
an early return in case of any nested calls. This way objects of the 3.
case also become more like the other object types.
I noticed this issue by enabling DMA debugging, which got disabled after
a while due to its internal mapping tables getting full. It also reported
errors in connection to random other drivers that did a DMA mapping for
an address that was previously mapped by i915 but was never released.
Besides these diagnostic messages and the memory space starvation
problem for IOMMUs, I'm not aware of this causing a real issue.
The fix is based on a patch from Chris.
v2:
- move the DMA mapping create/remove calls to the get_pages/put_pages
callbacks instead of adding new callbacks for these (Chris)
v3:
- also fix the get_page cache logic on the userptr async path (Chris)

The hang checker needs to inspect whether or not the ring request list is empty
as well as if the given engine has reached or passed the most recently
submitted request. The problem with this is that the hang checker cannot grab
the struct_mutex, which is required in order to safely inspect requests since
requests might be deallocated during inspection. In the past we've had kernel
panics due to this very unsynchronized access in the hang checker.
One solution to this problem is to not inspect the requests directly since
we're only interested in the seqno of the most recently submitted request - not
the request itself. Instead the seqno of the most recently submitted request is
stored separately, which the hang checker then inspects, circumventing the
issue of synchronization from the hang checker entirely.
This fixes a regression introduced in

Linux 4.2-rc1 Commit 0f20972f7bf6 ("dm: factor out a common
cleanup_mapped_device()") moved a common cleanup code to a separate
function. Unfortunately, that commit incorrectly changed the order of
cleanup, so that it destroys the mapped_device's srcu structure
'io_barrier' before destroying its workqueue.
The function that is executed on the workqueue (dm_wq_work) uses the srcu
structure, thus it may use it after being freed. That results in a
crash in the LVM test suite's mirror-vgreduce-removemissing.sh test.

The dasd device driver selects which (alias or base) device is used
for a given requests when the request is build. If the chosen alias
device is set offline before the request gets queued to the device
queue the starting function may use device structures that are
already freed. This might lead to a hanging offline process or a
kernel panic.
Add a check to the starting function that returns the request to the
upper layer if the device is already in offline processing.
In addition to that prevent that an alias device that's already in
offline processing gets chosen as start device.

Rather than (incompletely [0]) re-implementing drm_gem_mmap() and
drm_gem_mmap_obj() helpers, call them directly from the rockchip mmap
routines.
Once the core functions return successfully, the rockchip mmap routines
can still use dma_mmap_attrs() to simply mmap the entire buffer.
[0] Previously, we were performing the mmap() without first taking a
reference on the underlying gem buffer. This could leak ptes if the gem
object is destroyed while userspace is still holding the mapping.

This reverts commit dec4f799d0a4c9edae20512fa60b0a36f3299ca2.
Jörg Otte reports a NULL pointder dereference due to this commit, as
'crtc_state' very much can be NULL:
crtc_state = state->base.state ?
intel_atomic_get_crtc_state(state->base.state, intel_crtc) : NULL;
So the change to test 'crtc_state->base.active' cannot possibly be
correct as-is.
There may be some other minimal fix (like just checking crtc_state for
NULL), but I'm just reverting it now for the rc2 release, and people
like Daniel Vetter who actually know this code will figure out what the
right solution is in the longer term.

Commit 514ac99c64b "can: fix multiple delivery of a single CAN frame for
overlapping CAN filters" requires the skb->tstamp to be set to check for
identical CAN skbs.
Without timestamping to be required by user space applications this timestamp
was not generated which lead to commit 36c01245eb8 "can: fix loss of CAN frames
in raw_rcv" - which forces the timestamp to be set in all CAN related skbuffs
by introducing several __net_timestamp() calls.
This forces e.g. out of tree drivers which are not using alloc_can{,fd}_skb()
to add __net_timestamp() after skbuff creation to prevent the frame loss fixed
in mainline Linux.
This patch removes the timestamp dependency and uses an atomic counter to
create an unique identifier together with the skbuff pointer.
Btw: the new skbcnt element introduced in struct can_skb_priv has to be
initialized with zero in out-of-tree drivers which are not using
alloc_can{,fd}_skb() too.

The previous change 3973c526ae9c (net: can: c_can: Disable pins when CAN
interface is down) causes a slight glitch on the pinctrl settings when used.
Since commit ab78029 (drivers/pinctrl: grab default handles from device core),
the device core will automatically set the default pins. This causes the pins
to be momentarily set to the default and then to the sleep state in
register_c_can_dev(). By adding an optional "enable" state, boards can set the
default pin state to be disabled and avoid the glitch when the switch from
default to sleep first occurs. If the "enable" state is not available
c_can_pinctrl_select_state() falls back to using the "default" pinctrl state.

rcar_can_probe() regards 0 as a wrong IRQ #, despite platform_get_irq() that it
calls returns negative error code in that case. This leads to the following
being printed to the console when attempting to open the device:
error requesting interrupt fffffffa
because rcar_can_open() calls request_irq() with a negative IRQ #, and that
function naturally fails with -EINVAL.
Check for the negative error codes instead and propagate them upstream instead
of just returning -ENODEV.

Now that those apis are merged we implement them in the BLK driver
to guarantee that mmio aperture moves stay ordered with respect to
incoming read/write requests, and that writes are flushed through
those mmio-windows and platform-buffers to be persistent on media.

This patch adds hardware assisted scrolling. The code is based upon the
following investigation: https://parisc.wiki.kernel.org/index.php/NGLE#Blitter
A simple 'time ls -la /usr/bin' test shows 1.6x speed increase over soft
copy and 2.3x increase over FBINFO_READS_FAST (prefer soft copy over
screen redraw) on Artist framebuffer.

USB-serial fixes for v4.2-rc2
Here's an idr memory-leak fix and a couple of new device ids.
Included is also a build fix for mos7720 on the mn10300 architecture,
which has a register with the same name as one of the driver defines.
