The VF CCS save/restore series (patchwork #149108) has a dependency on the migration framework. A recent migration update in commitd65ff1ec85("drm/xe: Split xe_migrate allocation from initialization") caused a VM crash during XE driver release for iGPU devices. Oops: general protection fault, probably for non-canonical address 0x6b6b6b6b6b6b6b83: 0000 [#1] SMP NOPTI RIP: 0010:xe_lrc_ring_head+0x12/0xb0 [xe] Call Trace: xe_sriov_vf_ccs_fini+0x1e/0x40 [xe] devm_action_release+0x12/0x30 release_nodes+0x3a/0x120 devres_release_all+0x96/0xd0 device_unbind_cleanup+0x12/0x80 device_release_driver_internal+0x23a/0x280 device_release_driver+0x12/0x20 pci_stop_bus_device+0x69/0x90 pci_stop_and_remove_bus_device+0x12/0x30 pci_iov_remove_virtfn+0xbd/0x130 sriov_disable+0x42/0x100 pci_disable_sriov+0x34/0x50 xe_pci_sriov_configure+0xf71/0x1020 [xe] Update the VF CCS migration initialization sequence to align with the new migration framework changes, resolving the release-time crash.

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.
