This reverts commit 5a838e5d5825c85556011478abde708251cc0776.

Changes from commit 5a838e5d5825 ("drm/qxl: simplify qxl_fence_wait") would result in a '[TTM] Buffer eviction failed' exception whenever it reached a timeout.
Due to a dependency to DMA_FENCE_WARN this also restores some code deleted
by commit d72277b6c37d ("dma-buf: nuke DMA_FENCE_TRACE macros v2").

Hi,

This is the friendly patch-bot of Greg Kroah-Hartman. You have sent him
a patch that has triggered this response. He used to manually respond
to these common problems, but in order to save his sanity (he kept
writing the same thing over and over, yet to different people), I was
created. Hopefully you will not take offence and will fix the problem
in your patch and resubmit it so that it can be accepted into the Linux
kernel tree.

You are receiving this message because of the following common error(s)
as indicated below:

- You have marked a patch with a "Fixes:" tag for a commit that is in an
older released kernel, yet you do not have a cc: stable line in the
signed-off-by area at all, which means that the patch will not be
applied to any older kernel releases. To properly fix this, please
follow the documented rules in the
Documentation/process/stable-kernel-rules.rst file for how to resolve
this.

If you wish to discuss this problem further, or you have questions about
how to resolve this issue, please feel free to respond to this email and
Greg will reply once he has dug out from the pending patches received
from other developers.

thanks,

greg k-h's patch email bot
