Merge branch 'for-next/esr-elx-64-bit' into for-next/core

* for-next/esr-elx-64-bit:
  : Treat ESR_ELx as a 64-bit register.
  KVM: arm64: uapi: Add kvm_debug_exit_arch.hsr_high
  KVM: arm64: Treat ESR_EL2 as a 64-bit register
  arm64: Treat ESR_ELx as a 64-bit register
  arm64: compat: Do not treat syscall number as ESR_ELx for a bad syscall
  arm64: Make ESR_ELx_xVC_IMM_MASK compatible with assembly
