Mark Rutland aa6eece8ec arm64: add pointer authentication register bits ... The ARMv8.3 pointer authentication extension adds: * New fields in ID_AA64ISAR1 to report the presence of pointer authentication functionality. * New control bits in SCTLR_ELx to enable this functionality. * New system registers to hold the keys necessary for this functionality. * A new ESR_ELx.EC code used when the new instructions are affected by configurable traps This patch adds the relevant definitions to <asm/sysreg.h> and <asm/esr.h> for these, to be used by subsequent patches.
