If everything uses the right accessors, then enabling GENERIC_HARDIRQS_NO_COMPAT should just work. If not it will tell you. Don't be lazy and use the trick which I use in the core code! git grep status_use_accessors will unearth it in a split second. Offenders are tracked down and not slapped with stinking trouts. This time we use frozen shark for a better educational value. Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
