To permit batching of TLB flushes across multiple calls to the IOMMU driver's ->unmap() implementation, introduce a new structure for tracking the address range to be flushed and the granularity at which the flushing is required. This is hooked into the IOMMU API and its caller are updated to make use of the new structure. Subsequent patches will plumb this into the IOMMU drivers as well, but for now the gathering information is ignored. Signed-off-by: Will Deacon <will@kernel.org>
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.
