    tcache/tswap: enable by default
    
    These subsystems has proven to be stable, so let's enable them by
    default. If anything goes wrong, they can always be disabled by writing
    'N' to /sys/module/{tcache,tswap}/parameters/active.
    
    Currently tcache/tswap are enabled by vcmmd, but I want to drop this
    code from there.
