H A DKconfig.preempta50a3f4b6a313dc76912bd4ad3b8b4f4b479c801 Wed Jul 17 15:01:49 CDT 2019 Thomas Gleixner <tglx@linutronix.de> sched/rt, Kconfig: Introduce CONFIG_PREEMPT_RT

Add a new entry to the preemption menu which enables the real-time support
for the kernel. The choice is only enabled when an architecture supports
it.

It selects PREEMPT as the RT features depend on it. To achieve that the
existing PREEMPT choice is renamed to PREEMPT_LL which select PREEMPT as
well.

No functional change.
