 "This fixes the following issues:

   - oversize stack frames on mn10300 in sha3-generic

   - warning on old compilers in sha3-generic

   - API error in sun4i_ss_prng

   - potential dead-lock in sun4i_ss_prng

   - null-pointer dereference in sha512-mb

   - endless loop when DECO acquire fails in caam

   - kernel oops when hashing empty message in talitos"
