Kernel built for ppc64_defconfig, pseries_defconfig, iseries_defconfig,
cell_defconfig and pmac32_defconfig.  The latter failed because
check_media_bay is still undefined (i.e. for unrelated reasons).

This has been tested on a pseries_defconfig kernel using the posted test
program built for 64 and 32 bit.
