[PATCH v5 3/3] ARM: mm: use static_vm for managing static mapped areas

2013-02-04 Thread Joonsoo Kim
A static mapped area is ARM-specific, so it is better not to use generic vmalloc data structure, that is, vmlist and vmlist_lock for managing static mapped area. And it causes some needless overhead and reducing this overhead is better idea. Now, we have newly introduced static_vm infrastructure.
