Ok; and I take it
The functions get_online_cpus() and put_online_cpus() have been
deprecated during the CPU hotplug rework. They map directly to
cpus_read_lock() and cpus_read_unlock().
Replace deprecated CPU-hotplug functions with the official version.
The behavior remains unchanged.

This is a tree wide replacement of the deprecated CPU hotplug functions
which are only wrappers around the actual functions.

A framebuffer's offsets field might be non-zero to make the BO data
start at the specified offset within the BO's memory. Handle this
case in drm_gem_fb_vmap() and update all callers. So far, many drivers
ignore the offsets, which can lead to visual artifacts.
Patch 1 adds an optional argument to
Pass the data parameter to drm_gem_fb_vmap() to retrieve pointers
to the data. This address is different from the mapping addresses
for framebuffers with non-zero offsets. Replaces gud's internal
computation.

This patch adds IRQ support for the virtio GPIO driver. Note that this
uses the irq_bus_lock/unlock() callbacks, since those operations over
virtio may sleep. Also the notifications for the eventq are processed
using a work item to allow sleep-able operations.

This patch adds a new driver for Virtio based GPIO devices.
This allows a guest VM running Linux to access GPIO lines provided by
the host. It supports all basic operations, except interrupts for the
GPIO lines.
Based on the initial work posted by:
"Enrico Weigelt, metux IT consult" .
Hello,
This adds Virtio GPIO driver based on the proposed specification [1].
The specification for basic GPIO operations is already reviewed by Linus and
Arnd, while the IRQ stuff is still under discussion and not finalized.
I am sharing the code, so everyone gets more clarity on how it will

The device reset may fail in virtio-vdpa case now, so add checks to
its return value and fail the register_virtio_device().
So the reset() would be called by the driver during remove as well, or
is it sufficient to deal only with the reset during probe?
