- Have userspace pass a cpuset_t pointer and cpusetsize in the VM_RUN

The zone is used solely to provide KVA for mapping BIOs so that we can
pass mapped buffers to VOP_READ and VOP_WRITE. Currently we preallocate

The intent was to limit KVA usage on 32-bit systems, but the
preallocation means that we in fact consumed more KVA than needed unless
one has more than nswbuf/10 (typically 25) vnode-backed MD devices
in existence, which I would argue is the uncommon case.
Meanwhile, all I/O to an MD is handled by a dedicated thread, so we can
instead simply preallocate the KVA region at MD device creation time.

Modify when and how we perform parsing and reporting. Most notably,
everything now executes on CPU 0.
The de-facto standard way to enumerate CPU features (ISA extensions) on

information from the device tree, and in the future will be able to pull
it from ACPI tables.
Eliminate the SYSINIT from identcpu.c. We still need to walk the /cpus
list in the device tree, but now do this one CPU at a time, as a step in
the identify_cpu() procedure. This is slightly less error prone, and
allows us to parse ISA features for CPU 0 much earlier.
Make use of the SMP hooks cpu_mp_start() and cpu_mp_announce() to
identify and print secondary CPU info, respectively. This causes
secondary processor identification to be printed much earlier in boot;
everything is done by SI_SUB_CPU, SI_ORDER_THIRD. Adjust some other

Per the privileged specification, mvendorid contains the JEDEC vendor ID,

The marchid register denotes the CPU microarchitecture. This is either
one of the globally allocated open-source implementation IDs, or the
field has a custom encoding. Therefore, for known vendors (SiFive) we
can also maintain a list of known marchid values. If we can not give a
name to the CPU but marchid is non-zero, then just print its value in

The mimpid (implementation ID) could be used in the future to more

pw: do not move /home/$user to /usr/home
When adding a user, pw will create the path to the home directory
if needed. However, if creating a path with just one component,
i.e. that appears to be in the root directory, pw would create the
directory in /usr, and create a symlink from the root directory.
Most commonly, this meant that the default of /home/$user would turn
into /usr/home/$user. This was added in a self-described kludge 26
years ago. It made (some) sense when root was generally a small
partition, with most of the space in /usr. However, the default is
now one large partition. /home really doesn't belong under /usr,
and anyone who wants to use /usr/home can specify it explicitly.
Remove the kludge to move /home under /usr and create the symlink,
and just use the specified path. Note that this operation was
done only on the first invocation for a path, and this happened most
commonly when adding a user during the install.
Modify the test that checked for the creation of the symlink to
verify that the symlink is *not* made, but rather a directory.
