Subject: [PATCH 0/3] Lazy preemption leftovers

This is a followup to PeterZ'
	https://lore.kernel.org/20241007074609.447006177@infradead.org

in PREEMPT_RT we had initially "LAZY preempt" this then morphed into
PREEMPT_AUTO and is becoming "Lazy preemption". 
These are the tracing bits from that time that were used up to
PREEMPT_AUTO. With RT's RiscV support, they also contributed
PREEMPT_AUTO support which I just updated to current edition.

I used to have ARM* and POWERPC*, too support for the "LAZY preempt" but
this relied on assembly support and I dropped this during the switch to
PREEMPT_AUTO.
