This reverts commit 1addc1264852
This commit seems to cause crashes in gk104_fifo_intr_runlist() by returning 0xbad0da00 when register 0x2a00 is read. Since this commit was intended for GM20B which is not completely supported yet, let's revert it for the time being.

David, it would be great if this could be merged for 4.2 since lots of users could potentially experience this issue. Thanks!

Please help $subject reach mainline for 4.2, w/o this revert, the system here hangs most (>90%) of the time at boot time.
As an aside, yesterday after a marathon git bisect, came to the same solution (though I don't understand what that change means). Was about to report it and saw this one. Thanks Alexandre.
W/o the revert, in the rare case where it boots, below is observed in addition to as compared to w/ revert,
