The only thing I will say on this matter is that the _only_ way this
problem will go away is if someone does the work necessary to get rid
of that implicit vmalloc.h include that happens on all x86 platform
builds.

So if you want this to stop happening, work on that.

I've applied the following to net-next, thanks for your report.

====================
[PATCH] treewide: Add missing vmalloc.h inclusion.

All of these files were only building on non-x86 because of
the indirect of inclusion of vmalloc.h by, of all things,
"net/inet_hashtables.h"

None of this got caught during build testing, because on x86
there is an implicit vmalloc.h include via on of the arch asm/
headers.

This fixes all of these
