  s390/crypto: Enable CONTEXT_ANALYSIS (2026-09-08 15:53:41 +0200)

----------------------------------------------------------------
s390 updates for 7.3-rc3

- Fix NULL pointer dereferences in s390dbf when setting debug levels or
  resizing debug areas while logging events. Remove duplicate messages
  about kernel parameter overrides

- Fix PAI perf crashes when per task events move to newly onlined CPUs.
  Add CPU hotplug callbacks to allocate and free the per-CPU data

- Fix mutex use in atomic context in AES and PAES CTR code by using
  semaphore trylocks instead. Remove conditional locking and enable
  Clang CONTEXT_ANALYSIS for the crypto code

- Fix scatterlist walk error handling in AES and PAES and avoid freeing
  PAES walk resources twice

- Fix missing scrubbing of temporary AES and PAES buffers, including AES
  GCM error paths

- Set missing CRYPTO_ALG_ASYNC and CRYPTO_ALG_NO_FALLBACK flags for PAES

- Fix -EBUSY handling in PAES and PHMAC to avoid cleaning up requests
  already queued to the crypto engine

- Fix PAES and PHMAC requests being completed twice on errors

- Fix PAES and PHMAC hangs when key conversion keeps returning -EBUSY
  by returning -EIO after the last retry
