James Morse 8ddc58e0e3 arm64: errata: Remove AES hwcap for COMPAT tasks ... commit 44b3834b2e upstream. Cortex-A57 and Cortex-A72 have an erratum where an interrupt that occurs between a pair of AES instructions in aarch32 mode may corrupt the ELR. The task will subsequently produce the wrong AES result. The AES instructions are part of the cryptographic extensions, which are optional. User-space software will detect the support for these instructions from the hwcaps. If the platform doesn't support these instructions a software implementation should be used. Remove the hwcap bits on affected parts to indicate user-space should not use the AES instructions.
