  crypto: sha512 - Implement export_core() and import_core() (2025-09-02 19:02:39 -0700)

----------------------------------------------------------------

Fix a regression caused by my commits that reimplemented the sha1,
sha256, and sha512 crypto_shash algorithms on top of the library API.
Specifically, the export_core and import_core methods stopped being
supported, which broke some hardware offload drivers (such as qat)
that recently started depending on these for fallback functionality.

Later I'd like to make these drivers just use the library API for
their fallback. Then these methods won't be needed anymore. But for
now, this fixes the regression for 6.17.

      crypto: sha1 - Implement export_core() and import_core()
      crypto: sha256 - Implement export_core() and import_core()
      crypto: sha512 - Implement export_core() and import_core()
