* emailed patches from Andrew Morton <akpm@linux-foundation.org>:
kernel/hung_task.c: make type annotations consistent
epoll: add a selftest for epoll timeout race
mm: always have io_remap_pfn_range() set pgprot_decrypted()
mm, oom: keep oom_adj under or at upper limit when printing
kthread_worker: prevent queuing delayed work from timer_fn when it is being canceled
mm/truncate.c: make __invalidate_mapping_pages() static
lib/crc32test: remove extra local_irq_disable/enable
ptrace: fix task_join_group_stop() for the case when current is traced
mm: mempolicy: fix potential pte_unmap_unlock pte error
kasan: adopt KUNIT tests to SW_TAGS mode
mm: memcg: link page counters to root if use_hierarchy is false
