Subject: [PATCH v2 0/2] crypto: Fix memcpy_sglist()

This series rewrites memcpy_sglist() to fix the bug where it called
functions that could fail and ignored errors.

This series is targeting crypto/master.

Changed in v2:
    - Don't try to support arbitrary overlaps
    - Use memcpy_page()

Eric Biggers (2):
  crypto: scatterwalk - Fix memcpy_sglist() to always succeed
  Revert "crypto: scatterwalk - Move skcipher walk and use it for
    memcpy_sglist"
