+linux-6.1.76, 6.6.15, and 6.7.3 have modified the non-ARCH-specific
+pfn_valid() to use __rcu_read_lock/unlock[1] that is marked GPL and
+cannot be used here[2][3][4] unless use the open source variant.
+
+As a workaround, reuse the old implementation until NVIDIA makes
+a fixed release (due to no longer be using pfn_valid[5], likely
+with its own implementation similarly to this patch).
+
+Safe to use with kernel >=5.15 or so but older ones had a different
+pfn_valid implementation. However 5.15 and older branches are
+"currently" not affected, so simply limit to >=6.1.76.
