The flat_get_addr_from_rp() macro does not use the 'persistent' argument
on ARM, causing a harmless compiler warning. A cast to void removes
that warning.
Without this patch, building at91x40_defconfig results in:
fs/binfmt_flat.c: In function 'load_flat_file':
fs/binfmt_flat.c:746:17: warning: unused variable 'persistent'
[-Wunused-variable]

I can pick this one up to, and push to the arm-soc tree.
