Rather than return an error to the user or ban the VM when userptr VMA
page pin fails with -EFAULT, invalidate VMA mappings. This supports the
UMD use case of freeing userptr while still having bindings.
Now that non-faulting VMs can invalidate VMAs, drop the usm prefix for
the tile_invalidated member.
v2:
- Fix build error (CI)
v3:
- Don't invalidate VMA if in fault mode, rather kill VM (Thomas)
- Update commit message with tile_invalidated name chagne (Thomas)
- Wait VM bookkeep slots with VM resv lock (Thomas)
v4:
- Move list_del_init(&userptr.repin_link) after error check (Thomas)
- Assert not in fault mode (Matthew)

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.
