The ARMv8.3 PAuth (pointer authentication) extension adds:
- Fields in register ID_AA64ISAR1 to report the presence of pointer
authentication functionality.
- Control bits in SCTLR_ELx to enable this functionality.
- New registers to hold the keys necessary for this
functionality.
- New ESR_ELx.EC codes used when the new instructions are affected by
configurable traps
These will be used in later patches as support for pointer
authentication is added.
