[PATCH v3 0/2] Convert IB/mad to use an IDR for agent IDs

[Matthew Wilcox]

Thanks for the review / feedback / testing.  Here's v3.  Changes:

 - Split out the change to the IDR code into its own patch.
 - Dropped the "Agent registration is process context only" patch as
   Jason already merged it.
 - Added comment about why we're limiting the agent ID to 2^24.
 - Used a named constant instead of a bare '1 << 24'.
 - Updated the changelog to incorporate more of Hans' original message.
 - Added Tested-by, Acked-by and Reported-by to the second patch.
