bug#64369: Request for merging "mesa-updates" branch

[John Kehayias]

Hello all,

This is a request to merge the recently created "mesa-updates" branch. 
Currently there are just 2 patches on there, fixing/updating mesa only. The 
main thing to see is how substitute building goes in case anything breaks, but 
I'm hoping there isn't anything caused by this update.

I believe the "ruby-team" and "tex-team-next" [1] are ahead in the queue, not 
sure the timing of where those are. In addition/alternatively, would it make 
sense to have this branch as a separate build job on Cuirass directly as the 
"kernel-updates" branch? This would need a build roughly every month or so when 
mesa puts out a new update, we check for breakages, and then merge to master 
with substitutes available already.

I wasn't sure if this needs formal blockers in debbugs for the other branch 
merge requests, let me know!

Thanks,
John
