    x86: Eliminate redundant/contradicting cache line size config options · 350f8f56

    Rather than having X86_L1_CACHE_BYTES and X86_L1_CACHE_SHIFT
    (with inconsistent defaults), just having the latter suffices as
    the former can be easily calculated from it.
    To be consistent, also change X86_INTERNODE_CACHE_BYTES to
    X86_INTERNODE_CACHE_SHIFT, and set it to 7 (128 bytes) for NUMA
    to account for last level cache line size (which here matters
    more than L1 cache line size).
    Finally, make sure the default value for X86_L1_CACHE_SHIFT,
    when X86_GENERIC is selected, is being seen before that for the
    individual CPU model options (other than on x86-64, where
    GENERIC_CPU is part of the choice construct, X86_GENERIC is a
    separate option on ix86).
