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
