Use 'devm_add_action_or_reset()' instead of open coding it.
This makes the error handling code look more consistent.
This also save a few LoC.

The wrappers in include/linux/pci-dma-compat.h should go away.
The patch has been generated with the coccinelle script below and has been
hand modified to replace GFP_ with a correct flag.
It has been compile tested.

We need to always set ->need_cache_sync_on_prepare and
->need_cache_sync_on_finish when we initialize vb2 buffer.
Currently these flags are set/adjusted only in V4L2's
vb2_queue_or_prepare_buf(), which means that for the code
paths that don't use V4L2 vb2 will always tell videobuf2

While the overhead of userfaultfd is usually reasonable, this overhead

Hi,
I tried to upgrade my OMAP1 OSK board to v5.9, but the rootfs cannot
be accessed anymore due to broken USB. It fails to probe with the
following logs:

Hello,
This patch series adds management physical function driver for Xilinx Alveo PCIe
accelerator cards, https://www.xilinx.com/products/boards-and-kits/alveo.html
This driver is part of Xilinx Runtime (XRT) open source stack.
The patch depends on the "PATCH Xilinx Alveo libfdt prep" which was
Hello Pavel,
I got the following lockdep splat while rebasing my work on 5.10-rc5 on the

I did not actually confirm that the problem is triggered without my changes,
as my iouring workload requires some kernel changes (not iouring changes),

Hello,
This patch series adds support for exporting limited set of libfdt symbols from
Linux kernel. It enables drivers and other kernel modules to use libfdt for
working with device trees. This may be used by platform vendors to describe HW
features inside a PCIe device to its driver in a data
From: Sonal Santan
Some drivers may want to use device tree as metadata format to discover HW
subsystems behind PCIe BAR. This is particularly useful for PCIe FPGA
devices.

Possible. pr-tracker-bot obviously is back, it just had a very long delay.
And yes, the delay might have been due to it not seeing the original

Hi Vishawanath,

The only usage of these structs is to assign their address to the
thermal_zone_attribute_groups array, which consists of pointers to
