Ard Biesheuvel 68c76ad4a9 arm64: unwind: add asynchronous unwind tables to kernel and modules ... Enable asynchronous unwind table generation for both the core kernel as well as modules, and emit the resulting .eh_frame sections as init code so we can use the unwind directives for code patching at boot or module load time. This will be used by dynamic shadow call stack support, which will rely on code patching rather than compiler codegen to emit the shadow call stack push and pop instructions.
