    Subject[PATCH 05/10] x86: add X86_64 dependency to x86_64 specific symbols in Kconig.x86_64
    Date
    To ease unification of Kconfig.i386 and Kconfig.x86_64
    add X86_64 dependencies to all x86_64 specific symbols.

    This patch introduce no functional changes but is one step
    towards unification. This smaller step is used to ease
    review of the patch set.
