Module Name:    src
Committed By:   ad

        src/sys/sys: selinfo.h

Log Message:
Minor improvements to select/poll:

- Increase the maximum number of clusters from 32 to 64 for large systems.
  kcpuset_t could potentially be used here but that's an excursion I don't
  want to go on right now.  uint32_t -> uint64_t is very simple.

- In the case of a non-blocking select/poll, or where we won't block
  because there are events ready to report, stop registering interest in
  the back-end objects early.

- Change the wmesg for poll back to "poll".
