vmalloc: conditionalize build of pcpu_get_vm_areas()
No matching upstream commit as it was resolved differently there.
pcpu_get_vm_areas() is used only when dynamic percpu allocator is used
by the architecture. In 2.6.32, ia64 doesn't use dynamic percpu
allocator and has a macro which makes pcpu_get_vm_areas() buggy via
local/global variable aliasing and triggers compile warning.
The problem is fixed in upstream and ia64 uses dynamic percpu
allocators, so the only left issue is inclusion of unnecessary code
and compile warning on ia64 on 2.6.32.
Don't build pcpu_get_vm_areas() if legacy percpu allocator is in use.
