From: Bart Van Assche <bart.vanassche@xxxxxxx>
Subject: ARM: fix rd_size declaration
The global variable 'rd_size' is declared as 'int' in source file
arch/arm/kernel/atags_parse.c and as 'unsigned long' in
drivers/block/brd.c. Fix this inconsistency. Additionally, remove the
declarations of rd_image_start, rd_prompt and rd_doload from
parse_tag_ramdisk() since these duplicate existing declarations in
<linux/initrd.h>.
