Subject[PATCH smp 0/2] Provide CSD lock timeout diagnostics
Hello!

This is a sneak preview of a series providing diagnostics to help track
down problems that would result in excessive csd_unlock() latencies:

1. Add source and destination CPUs to __call_single_data.
I freely admit that I found the union declaration a
bit confusing!

2. Provide CSD lock timeout diagnostics.

Thanx, Paul
