Linus Torvalds ed4d6e9246 VFIO updates for v6.18-rc1 part 2
- Optimizations for DMA map and unmap opertions through the type1
    vfio IOMMU backend.  This uses various means of batching and hints
    from the mm structures to improve efficiency and therefore
    performance, resulting in a significant speedup for huge page
    use cases. (Li Zhe)
 
  - Expose supported device migration features through debugfs.

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 reStructuredText 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.
