Subject: [RFC v6 0/5] Implement full clockgating for Kepler1 and 2

Next version of my patchseries for adding clockgating support for
kepler1 and 2 on nouveau. The first version of this series can be found
here:

https://patchwork.freedesktop.org/series/36504/

Some small changes (shouldn't change anything functionally):
 - Made gf100_therm_new, gk104_clkgate_pack, and
   gk110_fb_clkgate_blcg_init_unk_0 static (re: kbuild test bot)
 - Making all three of these things static made it apparent that we
   create gf100_therm_new() and gf100_therm_func in
   nvkm/subdev/therm/gf100.c, but never actually use them anywhere. So,
   get rid of these two things entirely and also since we no longer need
   to, stop exporting gt215_therm_init
