Reviewed-by: Daniel Thompson Signed-off-by: Douglas Anderson --- In v9 this is the only kgdb dependency. I'm assuming it could go through the arm64 tree? If that's not a good idea, we could always change the patch ("arm64: kgdb: Roundup cpus using IPI as NMI") not to depend on it by only calling kgdb_nmicallback() if CONFIG_KGDB is not defined.
