Since commit f959dcd6ddfd
("dma-direct: Fix potential NULL pointer dereference")
an error is reported when we load vdpa_sim and virtio-vdpa:
[ 129.351207] net eth0: Unexpected TXQ (0) queue failure: -12
It seems that dma_mask is not initialized.
This patch initializes dma_mask() and calls dma_set_mask_and_coherent()
to fix the problem.

This patch introduces a new ioctl for vhost-vdpa device that can
report the iova range by the device.
For device that implements get_iova_range() method, we fetch it from
the vDPA device. If device doesn't implement get_iova_range() but
depends on platform IOMMU, we will query via DOMAIN_ATTR_GEOMETRY,
otherwise [0, ULLONG_MAX] is assumed.
For safety, this patch also rules out the map request which is not in
the valid range.

If riov and wiov are both defined and they point to different
objects, only riov is initialized. If the wiov is not initialized
by the caller, the function fails returning -EINVAL and printing
"Readable desc 0x... after writable" error message.
This issue happens when descriptors have both readable and writable
buffers (eg. virtio-blk devices has virtio_blk_outhdr in the readable
buffer and status as last byte of writable buffer) and we call
__vringh_iov() to get both type of buffers in two different iovecs.
Let's replace the 'else if' clause with 'if' to initialize both
riov and wiov if they are not NULL.
As checkpatch pointed out, we also avoid crashing the kernel
when riov and wiov are both NULL, replacing BUG() with WARN_ON()
and returning -EINVAL.

set_map() is used by mlx5 vdpa to create a memory region based on the
address map passed by the iotlb argument. If we get successive calls, we
will destroy the current memory region and build another one based on
the new address mapping. We also need to setup the hardware resources
since they depend on the memory region.
If these calls happen before DRIVER_OK, It means that driver VQs may
also not been setup and we may not create them yet. In this case we want
to avoid setting up the other resources and defer this till we get
DRIVER OK.

An architecture may restrict host access to guest memory,
e.g. IBM s390 Secure Execution or AMD SEV.
Provide a new Kconfig entry the architecture can select,
CONFIG_ARCH_HAS_RESTRICTED_VIRTIO_MEMORY_ACCESS, when it provides
the arch_has_restricted_virtio_memory_access callback to advertise
to VIRTIO common code when the architecture restricts memory access
from the host.
The common code can then fail the probe for any device where
VIRTIO_F_ACCESS_PLATFORM is required, but not set.

This patch fixes the issue by setting discard_granularity as SECTOR_SIZE
instead of 0 when (card->pref_erase > max_discard) is true. Now no more
complain from __blkdev_issue_discard() for the improper value of discard
granularity.
This issue is exposed after commit b35fd7422c2f ("block: check queue's
limits.discard_granularity in __blkdev_issue_discard()"), a "Fixes:" tag
is also added for the commit to make sure people won't miss this patch

Looks like the I2C tunnel implementation from Chromebook's
embedded controller does not handle PEC correctly. Fix this
by disabling PEC for batteries behind those I2C tunnels as
a workaround.
Note, that some Chromebooks actually have been reported to
have working PEC support (with I2C tunnel). Since the problem
has not yet been fully understood this simply reverts all
Chromebooks to not use PEC for now.

SCL rate appears to be different than what is expected. For example,
We get 164kHz on i2c3 of the vim3 when 400kHz is expected. This is
partially due to the peripheral clock being disabled when the clock is
set.
Let's keep the peripheral clock on after probe to fix the problem. This
does not affect the SCL output which is still gated when i2c is idle.

The pca953x driver never checks the result of irq_find_mapping(),
which returns 0 when no mapping is found. When a spurious interrupt
is delivered (which can happen under obscure circumstances), the
kernel explodes as it still tries to handle the error code as
a real interrupt.
Handle this particular case and warn on spurious interrupts.

It appears that UML (arch/um) has no compat.h header defined and hence
can't compile a recently provided piece of code in GPIO library.
Disable compat ->read() code in UML case to avoid compilation errors.
While at it, use pattern which is already being used in the kernel elsewhere.

When try_module_get() fails in the nvme_dev_open() it returns without
releasing the ctrl reference which was taken earlier.
Put the ctrl reference which is taken before calling the
try_module_get() in the error return code path.

Previously the code relied on device->pri to be NULL and to fail probing
later. We really should just return an error inside nvkm_device_ctor for
unsupported GPUs.

Pull another x86 platform driver fix from Hans de Goede:
"One final pdx86 fix for Tablet Mode reporting regressions (which make
the keyboard and touchpad unusable) on various Asus notebooks.
These regressions were caused by the asus-nb-wmi and the intel-vbtn
drivers both receiving recent patches to start reporting Tablet Mode /
to report it on more models.
Due to a miscommunication between Andy and me, Andy's earlier pull-req
only contained the fix for the intel-vbtn driver and not the fix for
the asus-nb-wmi code.
This fix has been tested as a downstream patch in Fedora kernels for
approx two weeks with no problems being reported"

Pull drm fixes from Dave Airlie:
"Daniel queued these up last week and I took a long weekend so didn't
get them out, but fixing the OOB access on get font seems like
something we should land and it's cc'ed stable as well.
The other big change is a partial revert for a regression on android
on the clcd fbdev driver, and one other docs fix.

- Re-add FB_ARMCLCD for android
- Fix global-out-of-bounds read in fbcon_get_font()

- Small doc fix"
