Marco ElverandGreg Kroah-Hartman 7753ef5ba2 kfence: skip __GFP_THISNODE allocations on NUMA systems ...

commit e64f81946a upstream.

On NUMA systems, __GFP_THISNODE indicates that an allocation _must_ be on
a particular node, and failure to allocate on the desired node will result
in a failed allocation.

Skip __GFP_THISNODE allocations if we are running on a NUMA system, since
KFENCE can't guarantee which node its pool pages are allocated on.

Fixes: 236e9f1538 ("kfence: skip all GFP_ZONEMASK allocations")
