[PATCH] ZVC: add __inc_zone_state for !SMP configuration
It turns out that there is a way to build a kernel with NUMA and no SMP.
In that case we are missing one definition __inc_zone_state.
Provide that missing __inc_zone_state.
(akpm: NUMA && !SMP sounds odd, but I am told "But there is the concept of
cpuless nodes. A NUMA system without SMP has a single processor but multiple
memory nodes. This used to work before on IA64 (wasn't aware of it, never seen
anyone with this kind of thing).")
