Linus Torvalds 785d21ba2f VFIO updates for v6.2-rc1
- Replace deprecated git://github.com link in MAINTAINERS. (Palmer Dabbelt)
 
  - Simplify vfio/mlx5 with module_pci_driver() helper. (Shang XiaoJing)
 
  - Drop unnecessary buffer from ACPI call. (Rafael Mendonca)
 
  - Correct latent missing include issue in iova-bitmap and fix support
    for unaligned bitmaps.  Follow-up with better fix through refactor.
    (Joao Martins)
 
  - Rework ccw mdev driver to split private data from parent structure,
    better aligning with the mdev lifecycle and allowing us to remove
    a temporary workaround. (Eric Farman)
 
  - Add an interface to get an estimated migration data size for a device,
    allowing userspace to make informed decisions, ex. more accurately
    predicting VM downtime. (Yishai Hadas)
 
  - Fix minor typo in vfio/mlx5 array declaration. (Yishai Hadas)
 
  - Simplify module and Kconfig through consolidating SPAPR/EEH code and
    config options and folding virqfd module into main vfio module.
    (Jason Gunthorpe)
 
  - Fix error path from device_register() across all vfio mdev and sample
    drivers. (Alex Williamson)
 
  - Define migration pre-copy interface and implement for vfio/mlx5
    devices, allowing portions of the device state to be saved while the
    device continues operation, towards reducing the stop-copy state
    size. (Jason Gunthorpe, Yishai Hadas, Shay Drory)
 
  - Implement pre-copy for hisi_acc devices. (Shameer Kolothum)
 
  - Fixes to mdpy mdev driver remove path and error path on probe.
    (Shang XiaoJing)
 
  - vfio/mlx5 fixes for incorrect return after copy_to_user() fault and
    incorrect buffer freeing. (Dan Carpenter)

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
