    157157Each core is supposed to have an unique hardware identifier, called '''gid''', hard-wired in a read-only register.
    158 From the kernel point of view a core is identified by a composite index (cxy,lid), where '''cxy''' is the cluster identifier, and ''lid'' is a local (continuous) index in the cluster. The association between the gid hardware index and the (cxy,lid) composite index is defined in the boot_info_t structure. In this first step, each core makes an associative search in the boot_info_t structure to obtain the ('''cxy,lid''') indexes from the '''gid''' index.
