The second one, i.e. [2/3], is something that hit my eye while browsing
the source and I verified that this is indeed an issue by printk'ing and
dumping the page tables.

The third one are excessive warnings from vmemmap_verify() due to Kasan's
NUMA_NO_NODE page populations.

urggggh.

That means these two series:

Yes, let's drop these and try again for 4.12. Thanks for the report
and the debug Nicolai!

Please don't lose track of

No, these are separate and are still valid for the merge window.

OK.  A bunch of rejects needed fixing.
