This commit adds prefetch support for SVM ranges, utilizing the
existing ioctl vm_bind functionality to achieve this.
v2: rebase
v3:
- use xa_for_each() instead of manual loop
- check range is valid and in preferred location before adding to
xarray
- Fix naming conventions
- Fix return condition as -ENODATA instead of -EAGAIN (Matthew Brost)
- Handle sparsely populated cpu vma range (Matthew Brost)
v4:
- fix end address to find next cpu vma in case of -ENOENT
v5:
- Move find next vma logic to drm gpusvm layer
- Avoid mixing declaration and logic
v6:
- Use new function names
- Move eviction logic to prefetch_ranges
v7:
- devmem_only assigned 0
- nit address
v8:
- initialize ctx with 0

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.
