Did you try x86_64 allmodconfig?  I'm getting a mess:

Presumably because we have memcontrol.h indirectly including mm.h which
includes vmstat.h (from a stupid place) and with this patch we have
vmstat.h including memcontrol.h.

Does the following fix the hexagon build?

vmstat.h depends on definitions in mm.h, but mm.h through the above
chain includes vmstat.h first. It worked in my x86 test because x86
pgtable.h doesn't include swap.h.

The headers are a bit of a mess. memcontrol.h is supposed to be a
lower level header than mm.h and vmstat.h, yet the new accounting
functions depend on mm.h definitions.

Let's move the lruvec accounting infra to vmstat.h and shuffle
memcontrol.h into the stack under mm.h and vmstat.h.

Does the following fix the hexagon build?
