Add several helpers to invalidate the caches after mappings in the affected domain are changed. - cache_tag_flush_range() invalidates a range of caches after mappings within this range are changed. It uses the page-selective cache invalidation methods. - cache_tag_flush_all() invalidates all caches tagged by a domain ID. It uses the domain-selective cache invalidation methods. - cache_tag_flush_range_np() invalidates a range of caches when new mappings are created in the domain and the corresponding page table entries change from non-present to present.

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.
