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.
