    Subject[PATCH] x86: make generic arch support NUMAQ - fix #2
    Date

    do not need reserve if it early scan smp table

    we are checking mptable early for numaq, so don't need to reserve_bootmem for
    it. bootmem is not there yet.

    do the samething like 64 bit.

    find it on 64g above system from 64 bit kernel kexec to 32 bit kernel with
    numaq support
