Hao Sun 0b7b8704dd mm: new primitive kvmemdup()
Similar to kmemdup(), but support large amount of bytes with kvmalloc()
and does *not* guarantee that the result will be physically contiguous. 
Use only in cases where kvmalloc() is needed and free it with kvfree(). 
Also adapt policy_unpack.c in case someone bisect into this.
