[PATCH 2/2] x86: add macro for_each_setup_data()

A common task for parsing setup_data is to iterate over setup_data's linked list, remap and do something and unmap. Now add macro for_each_setup_data() to do that. Signed-off-by: WANG Chao --- arch/x86/kernel/setup.c | 37 - 1 file changed, 12 insertions(+), 2
