Linux kernel source tree

Mixing GPU and CPU atomics does not work unless a strict migration policy of GPU atomics must be device memory. Enforce a policy of must be in VRAM with a retry loop of 3 attempts, if retry loop fails abort fault. Removing always_migrate_to_vram modparam as we now have real migration policy. v2: - Only retry migration on atomics - Drop alway migrate modparam v3: - Only set vram_only on DGFX (Himal) - Bail on get_pages failure if vram_only and retry count exceeded (Himal) - s/vram_only/devmem_only - Update xe_svm_range_is_valid to accept devmem_only argument v4: - Fix logic bug get_pages failure v5: - Fix commit message (Himal) - Mention removing always_migrate_to_vram in commit message (Lucas) - Fix xe_svm_range_is_valid to check for devmem pages - Bail on devmem_only && !migrate_devmem (Thomas) v6: - Add READ_ONCE barriers for opportunistic checks (Thomas) - Pair READ_ONCE with WRITE_ONCE (Thomas) v7: - Adjust comments (Thomas) Fixes: |

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.
