Hello!
The first four patches of this series consolidate RCU's dyntick-idle
counter manipulations into a set of access functions. These are currently
queued for 4.12 (merge window after next). The last patch in this series
uses the bottom bit of RCU's dyntick-idle counter to track a CPU's state,
and has been proposed to track the need to flush the local CPU's TLB.
This last patch will not be pushed until it has a use.
The patches are as follows:
1. Abstract the dynticks momentary-idle operation.
2. Abstract the dynticks snapshot operation.
3. Abstract dynticks extended quiescent state enter/exit operations.
4. Abstract extended quiescent state determination.
5. Maintain special bits at bottom of ->dynticks counter, which
might be used to track a given CPU's need to flush TLBs.
Thanx, Paul
