Pull libnvdimm fix from Dan Williams:
 "A minor regression fix.

  The libnvdimm unit tests were expecting to mock calls to
  ioremap_nocache() which disappeared in v5.5-rc1. This fix has appeared
  in -next and collided with some cleanups that Christoph has planned
  for v5.6, but he will fix up his branch once this goes in.

  Summary:

   - Restore the operation of the libnvdimm unit tests after the removal
     of ioremap_nocache()"

There is no a_r3, a_r4 in the testing topology.
It should be b_r1, b_r2. Also b_r1 mtu is 1400 and b_r2 mtu is 1500.

Expand dummy prog generation such that we can easily check on return
codes and add few more test cases to make sure we keep on tracking
pruning behavior.

  # ./test_verifier
  [...]
  #1066/p XDP pkt read, pkt_data <= pkt_meta', bad access 1 OK
  #1067/p XDP pkt read, pkt_data <= pkt_meta', bad access 2 OK
  Summary: 1580 PASSED, 0 SKIPPED, 0 FAILED

Also verified that JIT dump of added test cases looks good.

  tpm/tpm_ftpm_tee: add shutdown call back
  tpm: selftest: cleanup after unseal with wrong auth/policy test

Unseal with wrong auth or wrong policy test affects DA lockout
and eventually causes the tests to fail with:
"ProtocolError: TPM_RC_LOCKOUT: rc=0x00000921"
when the tests run multiple times.
Send tpm clear command after the test to reset the DA counters.

This test only works when [1] is applied, which was rejected.

Basically, the errors are reported and cleared. In this particular case of
tls sockets, following reads will block.

The test case was originally submitted with the rejected patch, but, then,
was included as part of a different patchset, possibly by mistake.
