    Subject[PATCH 2/2] x86: Increase MAXSMP CPU count to 8192
    The MAXSMP option is intended to enable silly large numbers of CPUs for
    testing purposes. The current value of 4096 isn't very silly any longer
    as there are actual machines that approach 6096 CPUs when taking HT into
    account. Increase the value to 8192 to account for this and short term
    future increases.
