Jun Kuriyama 9497adf974 - MFC r199067,199215,199253 
- Add hw.clflush_disable loader tunable to avoid panic (trap 9) at
    map_invalidate_cache_range() even if CPU is not Intel.

  - This tunable can be set to -1 (default), 0 and 1.  -1 is same as
    current behavior, which automatically disable CLFLUSH on Intel CPUs
    without CPUID_SS (should be occured on Xen only).  You can specify 1
    when this panic happened on non-Intel CPUs (such as AMD's).  Because
    disabling CLFLUSH may reduce performance, you can try with setting 0
    on Intel CPUs without SS to use CLFLUSH feature.

  - Amd64 init_secondary() calls initializecpu() while curthread is
    still not properly set up. r199067 added the call to
    TUNABLE_INT_FETCH() to initializecpu() that results in hang because
    AP are started when kernel environment is already dynamic and thus
    needs to acquire mutex, that is too early in AP start sequence to
    work.

    Extract the code that should be executed only once, because it sets
    up global variables, from initializecpu() to initializecpucache(),
    and call the later only from hammer_time() executed on BSP. Now,
    TUNABLE_INT_FETCH() is done only once at BSP at the early boot
    stage.
