Nothing major changed since the last version. I would be happy about

I was recently going over all users of PG_reserved. Short story: it is
difficult and sometimes not really clear if setting/checking for
PG_reserved is only a relict from the past. Easy to break things. I
guess I now have a pretty good idea wh things are like that
nowadays and how they evolved.

Any reason you skipped

drivers/gpu/drm/drm_pci.c:drm_pci_alloc()

and 

drivers/gpu/drm/drm_scatter.c:drm_legacy_sg_alloc()

which both look completely bogus as-is?

In fact we should probably just try to kill them off as they have
very few users left.
