    Subject[PATCH 22/27] x86: fix section mismatch in head_64.S:initial_code
    Date
    Fix following warning:
    WARNING: vmlinux.o(.cpuinit.data+0x0): Section mismatch in reference from the variable initial_code to the function .init.text:x86_64_start_kernel()

    initial_code are initially used to hold a function pointer
    from __init and later from __cpuinit. This confuses modpost
    and changing initial_code to REFDATA silence the warning.
    (But now we do not discard the variable anymore).
