From 033e48fb82958053113178264ddb9d5038d5e38b Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Fri, 14 Aug 2009 15:00:51 +0900 Subject: percpu: move pcpu_lpage_build_unit_map() and pcpul_lpage_dump_cfg() upward Unit map handling will be generalized and extended and used for embedding sparse first chunk and other purposes. Relocate two unit_map related functions upward in preparation. This patch just moves the code without any actual change.
