mm/vmalloc.c: change purge_ndoes as local static variable
Patch series "mm/vmalloc.c: code cleanup and improvements", v2.
These changes were made from code inspection in mm/vmalloc.c.
This patch (of 5):
Static variable 'purge_ndoes' is defined in global scope, while it's only
used in function __purge_vmap_area_lazy(). It mainly serves to avoid
memory allocation repeatedly, especially when NR_CPUS is big.
While a local static variable can also satisfy the demand, and can improve
code readibility. Hence move its definition into
__purge_vmap_area_lazy().
