It was used to early block fbdev dirty processing. Replace it with an
unprotected check of the par->dirty.active field. While this might
race with the vmw_fb_off() function, we do a protected check later so
the race will at worst lead to grabbing and releasing a couple of locks.

fbdev framebuffers were previously pinned to be able to keep them mapped
across updates.
This commit introduces a mechanism that instead revalidates the map on
each update, keeping the map cached across updates. The cached map is torn
down if the underlying pages change. Typically on buffer object moves and
swapouts.
This should be nicer to the system when we have resource contention.
Testing done: Basic fbdev functionality under Fedora 27.

The start / stop and preempt commands don't honor the context argument
but rather acts on all available contexts.
Also add detection for context 1 availability.
Note that currently there's no driver interface for submitting buffers
using the high-priority command queue (context 1).
Testing done:
Change the default context for command submission to 1 instead of 0,
verify basic desktop functionality including faulty command injection and
recovery.

This blit was previously performed using two large vmaps, one of which
was teared down and remapped on each blit. Use the more resource-
conserving TTM cpu blit instead.
The blit is used in boundary-box computing mode which makes it possible
to minimize the bounding box used in host operations.

The utility uses kmap_atomic() instead of vmapping the whole buffer
object. As a result there will be more book-keeping but on some
architectures this will help avoid exhausting vmalloc space and also
avoid expensive TLB flushes.
The blit utility also adds a provision to compute a bounding box of
changed content, which is very useful to optimize presentation speed
of ill-behaved applications that don't supply proper damage regions, and
for page-flips. The cost of computing the bounding box is not that
expensive when done in a cpu-blit utility like this.

Instead of switching capture mode depending on how many buffers are
available use a scratch buffer and always run in continuous mode. By
using a scratch buffer the responsiveness of the capture loop is
increased as it can keep running even if there are no buffers available
from userspace.
As soon as a userspace queues a buffer it is inserted into the capture
loop and returned as soon as it is filled. This is a improvement on the
previous logic where the whole capture loop was stopped and switched to
single capture mode if userspace did not feed the VIN driver buffers at
the same time it consumed them. To make matters worse it was difficult
for the driver to reenter continuous mode if it entered single mode even
if userspace started to queue buffers faster. This resulted in
suboptimal performance where if userspace where delayed for a short
period the ongoing capture would be slowed down and run in single mode
until the capturing process where restarted.
An additional effect of this change is that the capture logic can be
made much simple as we know that continuous mode will always be used.

Before starting a capture, allocate a scratch buffer which can be used
by the driver to give to the hardware if no buffers are available from
userspace. The buffer is not used in this patch but prepares for future
refactoring where the scratch buffer can be used to avoid the need to
fallback on single capture mode if userspace can't queue buffers as fast
as the VIN driver consumes them.

When loading the budget_av driver for ie. a KNC1 DVB-C TDA10024 card,
which makes use of the ttpci eeprom check functionality (that always

to the kernel log:

with the 'ff' being repeated for a total of 20 times. Improve that by
using the %*phC format specifier instead dprintk()'ing every byte of the

The bitfield dma_inuse is allocated of size dma_requests bits, thus a
valid bit address is from 0 to (dma_requests - 1).
When find_first_zero_bit() fails, it returns dma_requests as invalid
address.
Using such address for the following set_bit() is incorrect and, if
dma_requests is a multiple of BITS_PER_LONG, it will cause a buffer
overflow.
Currently this driver is only used in DT stm32h743.dtsi where a safe value
dma_requests=16 is not triggering the buffer overflow.
Fixed by checking the return value of find_first_zero_bit() _before_
using it.

This reverts commit 2170dd04316e0754cbbfa4892a25aead39d225f7
The intent of commit 2170dd04316e ("vfio-pci: Mask INTx if a device is
not capabable of enabling it") was to disallow the user from seeing
that the device supports INTx if the platform is incapable of enabling
it. The detection of this case however incorrectly includes devices
which natively do not support INTx, such as SR-IOV VFs, and further
discussions reveal gaps even for the target use case.

The persistence domain is a point in the platform where once writes
reach that destination the platform claims it will make them persistent
relative to power loss. In the ACPI NFIT this is currently communicated
as 2 bits in the "NFIT - Platform Capabilities Structure". The bits
comprise a hierarchy, i.e. bit0 "CPU Cache Flush to NVDIMM Durability on
Power Loss Capable" implies bit1 "Memory Controller Flush to NVDIMM
Durability on Power Loss Capable".
Commit 96c3a239054a "libnvdimm: expose platform persistence attr..."
shows the persistence domain as flags, but it's really an enumerated
hierarchy.
Fix this newly introduced user ABI to show the closest available
persistence domain before userspace develops dependencies on seeing, or
needing to develop code to tolerate, the raw NFIT flags communicated
through the libnvdimm-generic region attribute.

In case we failed to create UMR resources, mark them as invalid so we
won't try to destroy them on the unwind path.
Add the relevant checks to destroy_umrc_res(), this is done for the
unlikely event ib_register_device() or create_umr_res() err out and we
try to destroy invalid objects.

Problem:
When unloading due to failure amdgpu_device_fini was called twice
which was leading to NULL ptr in amdgpu_irq_disable_all.
Fix:
Call amdgpu_device_fini only once from amdgpu_driver_unload_kms.

Mixed up exporter and importer here. E.g. while mapping the BO we need
to check the importer not the exporter.

Replace "cant" with "can't".
"cant" is not same as "Can not" or "Can't".
