Matthew Brost 3d420e9fa8 drm/xe: Rework GPU page fault handling
Add helper function to implement VMA (user binding) page faults, remove
unnecessary userptr.invalidate_link list del operation, retry on memory
pressure, remove unnecessary xe_vma_userptr_check_repin after rebinding,
remove unnecessary TLB invalidation, and always use vm->lock in write
mode. Changes help facilitate SVM page faults.

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.
