Tina Zhang 705c1cdf1e iommu/vt-d: Introduce batched cache invalidation
Converts IOTLB and Dev-IOTLB invalidation to a batched model. Cache tag
invalidation requests for a domain are now accumulated in a qi_batch
structure before being flushed in bulk. It replaces the previous per-
request qi_flush approach with a more efficient batching mechanism.

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.
