[PATCH 0/4] crypto: arm64 - use frame_push/pop macros

[Ard Biesheuvel]

We have a pair of macros on arm64 that can be used in asm code to set up
and tear down the stack frame when implementing a non-leaf function.

We will be adding support for shadow call stack and pointer
authentication to those macros, so that the code in question is less
likely to be abused for someone's ROP/JOP enjoyment. So let's fix the
existing crypto code to use those macros where they should be used.

Ard Biesheuvel (4):
  crypto: arm64/aes-neonbs - use frame_push/pop consistently
  crypto: arm64/aes-modes - use frame_push/pop macros consistently
  crypto: arm64/crct10dif - use frame_push/pop macros consistently
  crypto: arm64/ghash-ce - use frame_push/pop macros consistently
