Xe KMD doesn't work on Linux

[kode54]

Using the Xe KMD, with an updated xe_drm.h, synced between the latest linux-drm-xe-next kernel and this package, results in OpenCL tasks which cause my A770 LE 16GB to time out, but just for the OpenCL app. The result is that Blender live locks a single core until the process is terminated. Journal shows notices like this:

Mesa 23.2.0_devel.170325.5c287290d88 built with mesa-tkg-git, with PR 20418 and 22652 applied.

This package from 22.43.24558.r1615.g16db7cc890 using AUR package intel-compute-runtime-git, with makepkg -o and swapping in the xe_drm.h from above, and then makepkg -efi.
