[PATCH 44/49] x86, memblock: Use memblock_debug to control debug message print out

From: Yinghai Lu
Date: Tue Jul 06 2010 - 18:52:43 EST


Also let memblock_x86_reserve_range/memblock_x86_free_range could print out name if memblock=debug is
specified

will also print ther name when reserve_memblock_area/free_memblock_area are called.

-v2: according to Ingo, put " if (memblock_debug) " in one place
