[PATCH 0/1] Mark xe driver as BROKEN until fixed

[Simon Richter]

Hi,

until either of

 - https://patchwork.freedesktop.org/series/150230/

or the (same but rebased)

 - https://patchwork.freedesktop.org/series/151983/

goes in, the xe module will Oops on insmod when kernel page size is not 4kB.
This disables the module for the time being, and should be reverted for fixed
versions.

This should probably also be added to the stable kernel series which will
likely not receive the fix.

[PATCH 1/1] Mark xe driver as BROKEN if kernel page size is not 4kB

[Simon Richter]

This driver, for the time being, assumes that the kernel page size is 4kB,
so it fails on loong64 and aarch64 with 16kB pages, and ppc64el with 64kB
pages.

This is not the correct way to submit patches for inclusion in the
stable kernel tree.  Please read:
    https://www.kernel.org/doc/html/latest/process/stable-kernel-rules.html
for how to do this properly.
