[PATCH v2] crypto: arm/aes-ce - work around Cortex-A57/A72 silion errata

2020-11-25 Thread Ard Biesheuvel
ARM Cortex-A57 and Cortex-A72 cores running in 32-bit mode are affected by silicon errata #1742098 and #1655431, respectively, where the second instruction of a AES instruction pair may execute twice if an interrupt is taken right after the first instruction consumes an input register of which a si
