dmesg (up to last nouveau messages)

I have a gk106, current versions of libdrm, mesa, kernel (observed both with
-mainline and https://github.com/skeggsb/linux branch linux-4.15 as of a few
minutes ago), and there appears to be a memory leak with nouveau that eats up
about .5 GB every day. Killing X does nothing.

Attached is output of dmesg from the most recent boot of this machine. I've
also attached (in case it matters) dumps of /proc/meminfo and output of slabtop
after I ran X for about two weeks, then exited and killed all major daemons. 
More importantly, I've attached a few hundred lines of
/sys/kernel/debug/kmemleak (from the most recent boot). After the first few
entries, they all start looking the same (except for the address and age).
