Thomas Hellström 1a7b71805a drm/xe: Don't unnecessarily invoke the OOM killer on multiple binds
Multiple single-ioctl binds can be split up into multiple bind
ioctls, reducing the memory required to hold the bind array.

So rather than allowing the OOM killer to be invoked, return
-ENOMEM or -ENOBUFS to user-space to take corrective action.

v2:
- Add __GFP_NOWARN to __GFP_RETRY_MAYFAIL allocations to avoid
  spamming the kernel log if a recoverable allocation fails.

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.
