Hi Andrew,

After merging the akpm-current tree, today's linux-next build (powerpc
ppc64_defconfig) failed like this:

lib/show_mem.c: In function 'show_mem':
lib/show_mem.c:43:45: error: 'totalcma_pages' undeclared (first use in this function)
  printk("%lu pages reserved\n", (reserved - totalcma_pages));
                                             ^

Caused by commit b4e3647bb59d ("lib/show_mem.c: adds cma reserved
information").  totalcma_pages exists nowhere except these added lines.

I have reverted that commit (and its following fix) for today.
