From: Ankit Agrawal <ankita@nvidia.com> The GHES code allows calling of memory_failure() on the PFNs that pass the pfn_valid() check. This contract is broken for the remapped PFNs which fails the check and ghes_do_memory_failure() returns without triggering memory_failure(). Update code to allow memory_failure() call on PFNs failing pfn_valid().
