Message

This series is the last set of fixes for the Talitos driver.

We now get a fully clean boot on both SEC1 (SEC1.2 on mpc885) and
SEC2 (SEC2.2 on mpc8321E) with CONFIG_CRYPTO_MANAGER_EXTRA_TESTS:

v2: dropped patch 1 which was irrelevant due to a rebase weirdness. Added Cc to stable on the 2 first patches.

v3:
 - removed stable reference in patch 1
 - reworded patch 1 to include name of patch 2 for the dependency.
 - mentionned this dependency in patch 2 as well.
 - corrected the Fixes: sha1 in patch 4
 
v4:
 - using scatterwalk_ffwd() instead of opencodying SG list forwarding.
 - Added a patch to fix sg_copy_to_buffer() when sg->offset() is greater than PAGE_SIZE,
 otherwise sg_copy_to_buffer() fails when the list has been forwarded with scatterwalk_ffwd().
 - taken the patch "crypto: talitos - eliminate unneeded 'done' functions at build time"
 out of the series because it is independent.
 - added a helper to find the header field associated to a request in flush_channe()

Christophe Leroy (4):
  lib/scatterlist: Fix mapping iterator when sg->offset is greater than
    PAGE_SIZE
  crypto: talitos - move struct talitos_edesc into talitos.h
  crypto: talitos - fix hash on SEC1.
  crypto: talitos - drop icv_ool
