system having over 4GB RAM. That's due to:
1) the limit being u_int instead of u_long like vm.kmem_size (the limit is
half of vm.kmem_size by default for amd64);
2) sysctl handler g_journal_cache_limit_sysctl() using u_int instead of u_long.
The fix is to replace u_int with u_long for the kern.geom.journal.cache.limit
sysctl variable.
