Merge branches 'for-next/asm' and 'for-next/insn' into for-next/bti

Merge in dependencies for in-kernel Branch Target Identification support.

* for-next/asm:
  arm64: Disable old style assembly annotations
  arm64: kernel: Convert to modern annotations for assembly functions
  arm64: entry: Refactor and modernise annotation for ret_to_user
  x86/asm: Provide a Kconfig symbol for disabling old assembly annotations
  x86/32: Remove CONFIG_DOUBLEFAULT

* for-next/insn:
  arm64: insn: Report PAC and BTI instructions as skippable
  arm64: insn: Don't assume unrecognized HINTs are skippable
  arm64: insn: Provide a better name for aarch64_insn_is_nop()
  arm64: insn: Add constants for new HINT instruction decode
