Subject: drm/xe: Make usm.asid_to_vm allocation use GFP_NOWAIT
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=444d78578e8a79537e527b50fda17d6aa2d30b79;p=thirdparty%2Flinux.git

drm/xe: Make usm.asid_to_vm allocation use GFP_NOWAIT

Ensure the asid_to_vm lookup is reclaim-safe so it can be performed
during TLB invalidations, which is necessary for context-based TLB
invalidation support.
