FSF addresses used in PA sources are no longer valid and rpmlint
generates numerous warnings during packaging because of this.
This patch changes all FSF addresses to FSF web page according to
the GPL how-to: https://www.gnu.org/licenses/gpl-howto.en.html
Done automatically by sed-ing through sources.
The srbchannel is enabled if protocol version >= 30 and
SHM is available. There is also a module parameter
srbchannel=false that can be used for disabling the srbchannel.
The setup is done in these steps:
1) Server receives authentication (like today)
2) Server sends enable_srbchannel to client
3) Server sends memblock to client
4) Client receives enable_srbchannel
5) Client receives memblock
6) Client sends enable_srbchannel back to server
7) Client switches over
8) Server receives enable_srbchannel and switches over
