[PATCH 2/2] s390/mm: enable fixup_user_fault retrying

By passing a non-null flag we allow fixup_user_fault to retry, which enables userfaultfd. As during these retries we might drop the mmap_sem we need to check if that happened and redo the complete chain of actions. Signed-off-by: Dominik Dingel --- arch/s390/mm/pgtable.c | 29 ++
