Subject: x86 align highmem zone boundaries with NUMA
From: Andy Whitcroft <apw@xxxxxxxxxxxx>
When in x86 NUMA mode we allocate struct pages's node local and map them into
the kernel virtual address space in the remap space. This space cuts into the
end of ZONE_NORMAL. When we round ZONE_NORMAL down we must ensure we maintain
the zone boundary constraint, we must round to MAX_ORDER.
