Many dprintk's in vb2 use a hardcoded prefix with the function name. In
many cases that is now outdated. To keep things consistent the dprintk
macro has been changed to print the function name in addition to the "vb2:"
prefix. Superfluous prefixes elsewhere in the code have been removed.

The application should really always fill in bytesused for output
buffers, unfortunately the vb2 framework never checked for that.
So for single planar formats replace a bytesused of 0 by the length
of the buffer, and for multiplanar format do the same if bytesused is
0 for ALL planes.
This seems to be what the user really intended if v4l2_buffer was
just memset to 0.
I'm afraid that just checking for this and returning an error would
break too many applications. Quite a few drivers never check for bytesused
at all and just use the buffer length instead.

The videobuf2-core did not zero the 'planes' array in __qbuf_userptr()
and __qbuf_dmabuf(). That's now memset to 0. Without this the reserved
array in struct v4l2_plane would be non-zero, causing v4l2-compliance
errors.
More serious is the fact that data_offset was not handled correctly:
- for capture devices it was never zeroed, which meant that it was
uninitialized. Unless the driver sets it it was a completely random
number. With the memset above this is now fixed.
- __qbuf_dmabuf had a completely incorrect length check that included
data_offset.
- in __fill_vb2_buffer in the DMABUF case the data_offset field was
unconditionally copied from v4l2_buffer to v4l2_plane when this
should only happen in the output case.
- in the single-planar case data_offset was never correctly set to 0.
The single-planar API doesn't support data_offset, so setting it
to 0 is the right thing to do. This too is now solved by the memset.
All these issues were found with v4l2-compliance.

This patch adds support for the PCI-8604PW card equipped with four 878A.
It is unknown who the manufacturer of this card is and no drivers were
available during development of the patch. According to images found
online, the card is originally sold with Linux DVR software.
A CPLD on the card prevents the 878A from requesting access to the
bus until an initialization sequence has been issued via GPIOs. The
implemented sequence uses the minimum number of GPIOs needed to
successfully unlock bus access. As there are many more GPIOs connected
to the CPLD, it is very likely that some of the others have an influence
on the bus arbitration scheduling. This should be investigated further
in case of performance issues.
The tested card contains an EEPROM on one of the 878A, but it is
completely empty (i.e. contains only 0xff), so it is not possible
to detect the card.

In core_init make sure access to EDID DDC lines are disabled
before chip is powered up. Also DISABLE_AUTO_EDID before power up.
The correct setting is applied later when setting the EDID.
Some sources (MAC) kept on reading EDID even when Hotplug was low
and in the short period in core_init before the DDC lines was enabled
read a corrupt EDID.

Fix the use of __user in the check_array_args() prototype: instead of
using 'void * __user *' you should use 'void __user **' for sparse to
understand this correctly.
This also required the use of __force in the '*kernel_ptr = user_ptr'
assignment.
Also replace a wrong cast (void *) with the correct one (void **)
in check_array_args().
This fixes these sparse warnings:

The edid array is copied to kernelspace by the v4l2 core, so drivers
shouldn't see the __user annotation. This conforms to other structs like
v4l2_ext_controls where the data pointed to is copied to from user to
kernelspace.

These are caused by the call*op defines which do something like this:
(ops->op) ? ops->op(args) : 0
which is OK as long as op is not a void function, because in that case one part
of the conditional expression returns void, the other an integer. Hence the sparse
errors.
I've replaced this by introducing three variants of the call_ macros:
call_*op for int returns, call_void_*op for void returns and call_ptr_*op for
pointer returns.
That's the bad news. The good news is that the fail_*op macros could be removed
since the call_*op macros now have enough information to determine if the op
succeeded or not and can increment the op counter only on success. This at least
makes it more robust w.r.t. future changes.

The notify function is a void function, yet the v4l2_subdev_notify
define uses it in a ? : construction, which causes sparse warnings.
Replace the define by a static inline function and move it to
v4l2-device.h, which is where it belongs since it needs to know the
v4l2_device struct. This wasn't a problem when it was a define, but
as a static inline function this no longer compiles in v4l2-subdev.h.

The sn9c102 driver is deprecated. It was moved to staging in
anticipation of its removal in a future kernel version. However, USB
devices 0C45:6024 and 0C45:6025 are still handled by sn9c102 when
both sn9c102 and gspca_sonixb are enabled.
We must migrate all the users of these devices to the gspca_sonixb
driver now, so that it gets sufficient testing before the sn9c102
driver is finally phased out.

"vb2: only call start_streaming if sufficient buffers are queued"
the vb2 framework warns on (WARN_ON()) if all the active buffers
are not released when streaming is stopped, initially the vb2 silently
released the buffer internally if the buffer was not released by
the driver.
This patch fixes following issue:

"vb2: only call start_streaming if sufficient buffers are queued"
the vb2 framework warns on (WARN_ON()) if all the active buffers
are not released when streaming is stopped, initially the vb2 silently
released the buffer internally if the buffer was not released by
the driver.
This patch fixes following issue:

This patch fixes I/O errors with the sym53c8xx_2 driver when the disk
returns QUEUE FULL status.
When the controller encounters an error (including QUEUE FULL or BUSY
status), it aborts all not yet submitted requests in the function
sym_dequeue_from_squeue.
This function aborts them with DID_SOFT_ERROR.
If the disk has full tag queue, the request that caused the overflow is
aborted with QUEUE FULL status (and the scsi midlayer properly retries
it until it is accepted by the disk), but the sym53c8xx_2 driver aborts
the following requests with DID_SOFT_ERROR --- for them, the midlayer
does just a few retries and then signals the error up to sd.
The result is that disk returning QUEUE FULL causes request failures.
The error was reproduced on 53c895 with COMPAQ BD03685A24 disk
(rebranded ST336607LC) with command queue 48 or 64 tags. The disk has
64 tags, but under some access patterns it return QUEUE FULL when there
are less than 64 pending tags. The SCSI specification allows returning
QUEUE FULL anytime and it is up to the host to retry.

Commit 8f619b5429d9 ("powerpc/ppc64: Do not turn AIL (reloc-on
interrupts) too early") added code to set the AIL bit in the LPCR
without checking whether the kernel is running in hypervisor mode. The
result is that when the kernel is running as a guest (i.e., under
PowerKVM or PowerVM), the processor takes a privileged instruction
interrupt at that point, causing a panic. The visible result is that
the kernel hangs after printing "returning from prom_init".
This fixes it by checking for hypervisor mode being available before
setting LPCR. If we are not in hypervisor mode, we enable relocation-on
interrupts later in pSeries_setup_arch using the H_SET_MODE hcall.

Commits 11d4616bd07f ("futex: revert back to the explicit waiter
counting code") and 69cd9eba3886 ("futex: avoid race between requeue and
wake") changed some of the finer details of how we think about futexes.
One was a late fix and the other a consequence of overlooking the whole

The first change caused our documentation to be incorrect, and the
second made us aware that we need to explicitly add more details to it.

The vfs merge caused a latent bug to show up:
In file included from fs/ceph/super.h:4:0,
from fs/ceph/ioctl.c:3:
include/linux/ceph/ceph_debug.h:4:0: warning: "pr_fmt" redefined [enabled by default]
#define pr_fmt(fmt) KBUILD_MODNAME ": " fmt
^
In file included from include/linux/kernel.h:13:0,
from include/linux/uio.h:12,
from include/linux/socket.h:7,
from include/uapi/linux/in.h:22,
from include/linux/in.h:23,
from fs/ceph/ioctl.c:1:
include/linux/printk.h:214:0: note: this is the location of the previous definition
#define pr_fmt(fmt) fmt
^
where the reason is that <linux/ceph_debug.h> is included much too late
for the "pr_fmt()" define.
The include of <linux/ceph_debug.h> needs to be the first include in the
file, but fs/ceph/ioctl.c had for some reason missed that, and it wasn't
noticeable until some unrelated header file changes brought in an
indirect earlier include of <linux/kernel.h>.

Before the patch, it was possible to add two times the same tunnel:
ip l a vti1 type vti remote 10.16.0.121 local 10.16.0.249 key 41
ip l a vti2 type vti remote 10.16.0.121 local 10.16.0.249 key 41
It was possible, because ip_tunnel_newlink() calls ip_tunnel_find() with the
argument dev->type, which was set only later (when calling ndo_init handler
in register_netdevice()). Let's set this type in the setup handler, which is
called before newlink handler.
Introduced by commit b9959fd3b0fa ("vti: switch to new ip tunnel code").

This patch fixes the initialization of an array used in the TX
datapath that was mistakenly initialized together with the
RX datapath arrays. An out of range array access could happen
when RX and TX rings had different sizes.

O_APPEND handling there hadn't been completely fixed by Pavel's
patch; it checks the right value, but it's racy - we can't really
do that until i_mutex has been taken.
Fix by switching to __generic_file_aio_write() (open-coding
generic_file_aio_write(), actually) and pulling mutex_lock() above
inode_size_read().

Similarly to commit 43279500deca ("packet: respect devices with
LLTX flag in direct xmit"), we can basically apply the very same
to pktgen. This will help testing against LLTX devices such as
dummy driver (or others), which only have a single netdevice txq
and would otherwise require locking their txq from pktgen side
while e.g. in dummy case, we would not need any locking. Fix this
by making use of HARD_TX_{UN,}LOCK API, so that NETIF_F_LLTX will
be respected.

When the device is unplugged, the driver would try to disable the
device. Add checking the flag of RTL8152_UNPLUG to skip setting
the device when it is unplugged. This could shorten the time of
unloading the driver.

The sun4i-emac driver is rather primitive, and doesn't support
promiscuous mode. This makes usage such as bridging impossible,
which is a shame on virtualization capable HW such as the
Allwinner A20.
The fix is fairly simple: move the RX setup code to the ndo_set_rx_mode
vector, and add the required HW configuration when IFF_PROMISC is passed
by the core code.
This has been tested on a generic A20 box running a few virtual
machines hanging off a bridge with the EMAC chip as the link to the
outside world.

In v3.2 the Analog Devices ADT75 temperature sensor driver was removed
as an IIO driver and support for it was added to the LM75 HWMON driver.
But it was apparently overlooked to rename one reference to CONFIG_ADT75
to CONFIG_SENSORS_LM75. Do so now. Use the IS_ENABLED() macro, while
we're at it.
