mm: remove mm_init compilation dependency on CONFIG_DEBUG_MEMORY_INIT
Nishanth Aravamudan [Thu, 24 Jul 2008 04:27:39 +0000 (21:27 -0700)]
Towards the end of putting all core mm initialization in mm_init.c, I
plan on putting the creation of a mm kobject in a function in that file.
However, the file is currently only compiled if CONFIG_DEBUG_MEMORY_INIT
is set. Remove this dependency, but put the code under an #ifdef on the
same config option. This should result in no functional changes.
