[Stephen Rothwell <sfr@xxxxxxxxxxxxxxxx>]

Hi all,

After merging the dma-mapping tree, today's linux-next build (powerpc
ppc64_defconfig) produced this warning:

kernel/dma/coherent.c:325:29: warning: 'dma_reserved_default_memory' defined but not used [-Wunused-variable]
  325 | static struct reserved_mem *dma_reserved_default_memory __initdata;
      |                             ^~~~~~~~~~~~~~~~~~~~~~~~~~~

Introduced by commit
