connected topology in mailbox 6 when you're done getting your loop id

FL-Port. Add in some connection mode async events.
amount of physical memory, divide it by 4, and then allow machine
dependent code to place upper and lower bounds on the size. Export
the computed value to userspace via the new "vm.nkmempages" sysctl.
NKMEMCLUSTERS is now deprecated and will generate an error if you
attempt to use it. The new option, should you choose to use it,
is called NKMEMPAGES, and two new options NKMEMPAGES_MIN and
NKMEMPAGES_MAX allow the user to configure the bounds in the kernel
config file.
increasing both of them will result in negative number on udp

of virtual address space, leaving userland with 3G, and update comments
to match the new reality.
We knew we were going to have to bite this bullet eventually, and there
are a couple of outstanding PRs related to this issue (9389 and 9313).
Complete solution to those PRs is going to involve some sort of run-time
decision on how large kmem_map should be, as well as changing some data
structure allocation strategies in UVM. However, this change will at
least allow the PR submitter to simply throw resources at the problem.

1) fix typo preventing compilation (missing comma).
2) in SLOCK_WHERE, display cpu number in the MP case.
3) the folowing race condition was observed in _simple_lock:
cpu 1 releases lock,
cpu 0 grabs lock
cpu 1 sees it's already locked.
cpu 1 sees that lock_holder== "cpu 1"
cpu 1 assumes that it already holds it and barfs.
cpu 0 sets lock_holder == "cpu 0"
Fix: set lock_holder to LK_NOCPU in _simple_unlock().
