Test on gpu-dev03 (AMD Radeon HD7970)
Fix reading of Gaugefields from ILDG files
The internally allocated buffer into which the read gauge field was written was not
passed back to the caller. Not only was the memory lost, but the caller was reading
some random location in memory instead of the read gauge field.
refs #700: Had to fix this on the way…
Safer initialization of Gaugefield
Do not dereference an uninitialized PRNG pointer.
Christopher, I am just assigning this to you for review so you are informed about the change in 78f5b720.
In case you are observing any performance degradation or other issue will will have to look for a different workaround. Otherwise please close the ticket.

Thanks, Matthias. It`s quite unfortunate that the kernel has to be split like this, but of course the newer driver should be usable.
Regarding the performance, I did not do any benchmarks. Anyway, I guess that the new driver will enhance performance on newer cards.
Would you guess that there is an overhead due to the increased number of kernels. It should be similar to the dslash..
In case I would create a ticket, but I think it should not be an issue..
