[PATCH] x86-64: fix .init section reference warnings

["Jan Beulich" <jbeulich@novell.com>]

The change in head_64.S is needed because ld -r renames .init.data to
.init.data.<number> for all but the first instance due to mismatching
section attributes.
The change in init_64.c is necessary because find_early_table_space()
is called from a __meminit function, but calls itself an __init one.
