[PATCH 1/1] vmalloc: Remove static declaration of va from __get_vm_area_node

[PATCH 1/1] vmalloc: Remove static declaration of va from __get_vm_area_node

[Kautuk Consul]

Static storage is not required for the struct vmap_area in
__get_vm_area_node.

Removing "static" to store this variable on the stack instead.
