It's not entirely clear to me why this patch is included in a patchset
for the ice driver.
And it's also not clear to me why, but allmodconfigs - fo4 at least x86_32
and x86_64 - fail with this patch applied to net-next [1].
ERROR: modpost: "__bitmap_weighted_or" [drivers/gpu/drm/xe/xe.ko] undefined!
